A Software Engineer at UTHealth Houston serves as a vital bridge between complex healthcare data and the clinical and administrative systems that power one of the nation’s leading academic health centers. You will be responsible for designing, maintaining, and optimizing software solutions that support medical research, patient care, and operational efficiency. Whether you are working on MyChart EPIC integrations, revenue cycle management tools, or bioinformatics pipelines, your contributions directly impact the ability of healthcare professionals to provide high-quality care.
This role is unique because it requires more than just technical proficiency; it demands a high degree of empathy and communication. You will frequently interact with stakeholders who may not have a technical background, meaning you must be able to translate complex engineering concepts into actionable insights. Working at UTHealth Houston means operating within a mission-driven environment where the scale of data is vast and the stakes are high, making this an ideal position for engineers who are passionate about applying technology to improve human health.
Because UTHealth Houston is a research-heavy academic environment, emphasize your ability to document your work clearly and communicate across disciplines, as you will often work with PIs (Principal Investigators) and clinical staff.
Initial Screening
reportedThe title covers product work, platform work, infrastructure, mobile and frontend, and those are different jobs with different loops behind them. A screening call is the cheapest place to find out which one the seat is, and asking reads as experienced rather than fussy. The questions that separate them: what the team is on call for, what the last three projects were, and whether any round happens inside an existing repository instead of a blank file. Then say which of that you have done and which you have not. Claiming the whole posting is the fastest way to be found out one round later.
What to demonstrate
- Whether you can locate your experience inside one flavour of the role honestly instead of claiming the entire requirements list
- Whether you name what you have not done, which an experienced screener reads as a level signal and can plan the loop around
- Whether what you want next matches what the seat is: someone who wants greenfield work landing on a team that mostly operates an existing system is a hire that leaves within the year
How to prepare
- Mark every line of the posting as done, adjacent or new, and write one sentence for each adjacent line naming the closest thing you actually built
- Split your last two years into rough percentages across feature work, operating and debugging live systems, and design or review, so a question about scope gets numbers rather than adjectives
- Bring three questions that discriminate between seats: what the team is paged for, how much of the work is changing existing code versus standing up something new, and what shipped in the last quarter
Technical Discussions
reportedInput bounds are the part of the prompt most often skimmed, and they usually contain the answer. They tell you which complexity class is admissible, which narrows the search before you have thought about the problem itself. As a rough planning figure, a compiled language does on the order of 10^8 simple operations per second and an interpreted one roughly an order of magnitude less. So n up to about twenty admits enumerating subsets, a few thousand admits a quadratic pass, and a million admits neither: you need near-linear, or linear with a log factor. If the bounds are missing, ask for them.
What to demonstrate
- Whether the approach is justified by the stated input size rather than by whichever pattern you recognised first
- Whether you ask about the properties that change the algorithm: whether the input arrives sorted, whether duplicates occur, whether values are bounded integers, whether it all fits in memory
- Whether you can name the bottleneck in your own solution and what would remove it, even when you deliberately leave it in place
- Whether a claimed speedup is real, since memoising a recursion only helps when subproblems genuinely overlap and the state can be keyed cheaply
How to prepare
- For each algorithm you rely on, write down the largest n it handles in roughly a second, then check two of those figures by timing them in the language you will actually type in
- For two weeks, write one line naming your target complexity and the bound that justifies it before you write any code, then compare that line with what you ended up submitting
- Practise the conversion backwards: given a required O(n log n), list the mechanisms that get you there (sorting, a heap, an ordered map, divide and conquer) and choose by what the problem needs to query, not by what you used last
Behavioral Conversations
reportedMany of these questions are about something that went wrong, and the grading sits mostly in the hours after you knew. Who found out first, whether that was you or an alert or a user, how long it took you to say it out loud, and whether the people who needed the news got it while they could still act on it. Engineers under-tell this part because it feels like confessing. The pattern it is looking for is the opposite: the quiet fix, an incident absorbed without telling anyone, after which nothing changed and the same failure is still available.
What to demonstrate
- How the problem was found, and whether that route was one you had built or one that happened to you, since a user reporting it first means your instrumentation did not cover that failure
- Whether time-to-detect and time-to-tell are separate numbers in your account and whether you know both, because a fast fix that nobody heard about until the retro is a different answer from a slow one that was announced immediately
- Whether the resolution left something durable behind, a check that fires or a default that changed, rather than depending on people remembering to be careful
- Whether you can say what the failure cost without either inflating it or waving it away
How to prepare
- Reconstruct one incident you were part of as a timeline with clock times: first bad request, first signal, first person who knew, first message outside the team, mitigation, permanent fix. The gaps between those entries are what gets asked about
- Look up the configuration of the signal that caught it, including its evaluation window and threshold. An alert defined on a five-minute aggregate cannot fire until the condition holds across that window, which puts a floor under time-to-detect that has nothing to do with how severe the failure was. Be able to say what that floor was and whether anyone had chosen it deliberately
- Prepare one story where you escalated early and the severity turned out to be smaller than you thought, including what it cost the people you pulled in. Without it, every answer you give about raising alarms is unfalsifiable
Management-Level Discussions
reportedBecause the format is not fixed, the first job in the room is classification. Listen to the opening question and decide what it is: a probe into work you have already described, a fresh problem to solve now, or a conversation about how you operate. Each wants a different register, and the common failure is forcing a rehearsed structure onto a question that did not ask for it. Running a full design ritual on a ten-minute debugging question reads as not listening. When you cannot tell which it is, ask how long they want to spend and answer at that depth.
What to demonstrate
- Whether the shape of your answer matches the question, so a yes-or-no gets answered before it is justified and an open prompt gets a direction before a detour
- Whether you check how much depth is wanted instead of deciding for them, and whether you stop when the answer is complete rather than continuing until someone interrupts
- Whether you can be redirected in the middle of an answer without restarting it from the beginning
- Whether a question outside your experience gets an honest boundary followed by reasoning from what you do know, instead of a confident answer with nothing behind it
How to prepare
- Rehearse one project at three lengths, roughly thirty seconds, three minutes, and a full walkthrough at the depth of a design review, and practise switching between them when someone interrupts mid-telling
- Have someone ask you five questions of deliberately mixed type in one sitting without telling you the types, and score only whether you identified each one correctly before you started answering
- Draft the sentence you will use to check depth, along the lines of asking whether the short version is useful here or they want the detail, and use it in a real conversation this week so the day of the round is not its first outing
PracHub editorial advice for the preparation topics above.
Treating a medical record number or a member ID as a globally unique key and joining on it directly.
These identifiers are unique only within the authority that issued them. Two facilities in one network routinely have the same medical record number for different people, and member IDs get reissued when someone changes plans. Joining on the bare value merges two patients' records, which is the most damaging failure available in this domain, and it passes every test written against a single-facility fixture because the collision only appears once a second source is connected.
Storing monetary amounts as floating-point numbers.
Binary floating point cannot represent values like 0.10 exactly, so summing allowed and paid amounts across millions of claim lines accumulates representation and rounding error. Reconciliation against a remittance file is exact to the cent, so the drift surfaces as a balance that is off by a few cents with no identifiable cause, and engineers lose days looking for a logic bug in code that is correct apart from its numeric type. Integer minor units or an exact decimal type removes the class entirely.
Writing code before the input contract is pinned down
Before the first line, state the types, the size bounds, whether duplicates, negatives or an empty input are possible, whether the input is sorted, whether you may mutate it, and what the function returns when nothing matches. Every one of those answers changes the code, and discovering one at minute twenty costs a rewrite you no longer have time for.
Not asking what the system looks like if it dies halfway through
For any multi-step write, say what state remains if the process stops between step two and step three, and what brings it back: a single transaction, a saga with compensating actions, an outbox, or a reconciliation job. Partial failure is routine at any real call volume, so 'that shouldn't happen' is an answer with nothing behind it.

Group transfer-chained encounters into episodes with out-of-order arrival
You have up to 5 million encounter rows for a reporting month, in arbitrary order: encounter_id, enterprise_person_id, facility_id, encounter_class, admit_ts, discharge_ts (nullable), status, prior_encounter_id (nullable, set on transfer), source_event_ts. prior_encounter_id may reference a row that arrives later or never arrives. Group rows into episodes, one per maximal transfer chain, returning episode root, person, earliest admit_ts, latest discharge_ts (null if any member is still open) and member count. Report cycles instead of following them. Target O(N) expected time.
Approach
- Recognise the shape: every row has at most one prior_encounter_id, so this is a forest of parent pointers, not a general graph. A hash map from encounter_id to row is the whole index you need, and the work is O(N) expected rather than anything sort-shaped.
- Resolve roots by iterative pointer-following with write-back memoisation: from each node walk prior_encounter_id until you reach a node with no parent, a parent absent from the input, or a node whose root is already known, then stamp the discovered root onto every node on that path. Each node is finalised once, so total work stays O(N) even when one chain is very long.
- Do not recurse. A malformed feed can produce a chain tens of thousands deep, and a recursive resolver dies on stack depth taking the whole batch with it. An explicit loop with write-back is both faster and bounded.
- Detect cycles with three-state marking: unvisited, on the current path, finalised. On reaching a node that is on the current path, emit a data-quality record naming every encounter_id in the cycle and exclude that component from the episode output. Choosing an arbitrary root instead would produce an episode that looks plausible and will be believed.
- Keep a dangling prior_encounter_id distinct from a genuine root. It means the chain starts outside the window or has not arrived, so flag the episode left-truncated and carry that flag into the output: an episode with an unknown start cannot be used for length of stay or readmission counting without biasing both downward.
- Compute aggregates during the same pass that assigns roots: minimum admit_ts, maximum discharge_ts with null propagation so any open member leaves the episode open, and exclude cancelled and entered_in_error members from the aggregates while keeping them retrievable.
Worked solution 25 min
- Load all rows into a hash map keyed by encounter_id, with a colour array alongside.
- For each unfinalised node, walk parents onto an explicit path stack until you hit a root, a dangling reference, a finalised node or an on-path node.
- Stamp the resolved root, or the cycle marker, back onto every node on the path.
- Fold each node into its root's aggregate: min admit_ts, max discharge_ts with null propagation, member count, left-truncated flag.
- Emit episodes and the cycle records as two separate outputs.
Follow-up
- Two encounters name each other as prior_encounter_id. What does your detector emit, and who needs to see it?
- One episode spans two facilities whose clocks differ by four seconds. Do you order on source_event_ts or admit_ts, and what does the choice cost?
- A chain is cut in half by the month boundary. What does this month's report say, and how do you make next month's agree with it?
Denormalise consent into a decision table with a stated staleness bound
Access governance answers 'may this requester read this person's data for this purpose' on every identified read — tens of thousands per second at a 5ms p99 — from consent_directive: consent_id, enterprise_person_id, version, scope, purpose_of_use text[], grantee_org_id (NULL meaning all organisations), permit boolean, effective_ts, expires_ts, revoked_ts, status. Evaluating the normalised version history per read misses the budget. Design the denormalised decision store and its key, state the revocation staleness bound in seconds and the mechanism that actually enforces it, and say which normalised rows remain the system of record and why.
Approach
- Derive the shape from the read, not from the source table. The read is a point lookup on (person, grantee organisation, purpose), so fan the purpose_of_use array out into one row per purpose and make those three columns the primary key. A GIN index on the array would serve containment queries nobody issues.
- Handle the wildcard concretely. grantee_org_id NULL means 'all organisations', and NULL never equals anything, so a nullable column in the key breaks both the primary key and the equality lookup. Store a sentinel org id of 0 for the wildcard and resolve specific-before-wildcard in the lookup, or the wildcard row is silently unreachable.
- Make refusal a row, not an absence. An explicit permit = false must outrank a permit for the same key, so carry a precedence rank (specific grantee beats wildcard, refusal beats permit at equal specificity) and resolve with ORDER BY rank LIMIT 1. Default deny when nothing matches, so a rebuild failure fails closed.
- Separate the two staleness mechanisms and be precise about which one is the bound. The in-process decision cache has a TTL; a revocation also publishes an invalidation. The publish shortens the typical case to milliseconds, but it can be lost, so the guaranteed bound is the TTL alone — quote that number, for example 30 seconds, and justify it against the cache hit rate you need to hold 5ms p99.
- Evaluate expires_ts at read time against the request clock rather than baking the decision. A cached permit whose expires_ts has passed is wrong regardless of invalidation, because no event fires when a timestamp simply goes by.
- Keep consent_directive as the system of record: audit must reconstruct the directive in force at any past instant, the decision table holds only current state, and a corrupted decision table must be rebuildable by replaying the directives. Bound the write amplification by keeping grantees at organisation granularity and purposes a closed code set, so one directive expands to a known small number of rows rather than an unbounded cross product.
Worked solution 40 min
- Write the decision table DDL with the three-column primary key, the sentinel wildcard, the precedence rank and a monotonic decision_version.
- Write the lookup query: equality on the key with the wildcard row unioned in, ORDER BY rank, LIMIT 1, and an expires_ts predicate evaluated against the request timestamp.
- Write the projection that turns one consent_directive version into its decision rows, and compute the expansion factor for a directive covering four purposes and one organisation.
- State the TTL, then justify it: at N reads per second and M people, compute the cache hit rate the TTL yields and check it against the 5ms p99 budget.
- Write the failure narrative for a lost invalidation and confirm the TTL, not the bus, is what caps exposure.
- Write the rebuild procedure from consent_directive and the assertion that proves the rebuild is complete before it is swapped in.
Follow-up
- Break-glass must always succeed and must be unmistakably marked. Where does it sit relative to this lookup, and what stops it from becoming the quiet default path?
- The invalidation bus is down for thirty minutes. Walk through what a revoked person's data exposure looks like minute by minute, and what the backlog does when the bus returns.
- Where does the access audit record get written so that an audit-store outage degrades neither the log's completeness nor the read's availability?
Return the displayable version of each analyte with a window function
observation_result is append-only: observation_id, enterprise_person_id, encounter_id, accession_id, placer_order_id, filler_order_id, loinc_code, value_numeric, unit_ucum, result_status in ('registered','preliminary','final','amended','corrected','entered_in_error'), collected_ts, issued_ts, version, supersedes_observation_id. A chart view needs the currently displayable value for each (accession_id, loinc_code) for one person over the last 90 days, excluding analytes whose newest version is entered_in_error but keeping analytes whose older versions were. Write the query, give the index that serves it, and say honestly which part of the plan the index cannot remove.
Approach
- Recognise the shape: this is a top-1-per-group over a version chain, not a filter. Pick the newest version first, then apply the status predicate to the winner — the order is the whole exercise.
- Use DISTINCT ON (accession_id, loinc_code) with ORDER BY accession_id, loinc_code, version DESC, observation_id DESC on PostgreSQL; the ORDER BY must start with the DISTINCT ON expressions or it is a syntax error. Use ROW_NUMBER() OVER (PARTITION BY ... ORDER BY version DESC, observation_id DESC) with an outer WHERE rn = 1 if you need portability, since a window function cannot be referenced in the WHERE of its own query level.
- Push only person and time into the inner WHERE. Pushing result_status <> 'entered_in_error' inside promotes a retracted result's predecessor back onto the chart, which is the bug the prompt is testing for.
- Index (enterprise_person_id, collected_ts DESC) so the 90-day slice is an index range scan rather than a scan of the person's whole history.
- Be straight about the limit: because collected_ts carries a range predicate, no b-tree index can also deliver rows pre-ordered by (accession_id, loinc_code, version DESC), so the sort stays in the plan. That is acceptable because one person's 90-day slice is hundreds to low thousands of rows, and it is a quicksort in work_mem rather than an external merge — verify that rather than assume it.
Follow-up
- A correction arrives carrying the same filler_order_id and the same version number as the row it corrects. What breaks, and what do you add to the sort key?
- The same query for a cohort of 50,000 people instead of one person: does DISTINCT ON still hold up, and at what point do you materialise a latest-version table with a partial index?
- How would you show the clinician that the displayed value was amended, given the chart query returns only the winner?

Enrolment loading, bitemporal writes and retroactive fan-out
A weekly X12 enrolment file carries between tens of thousands and two million member rows and routinely terminates coverage retroactively — received on the fifth, effective the first. It writes coverage_span, whose effective_date and termination_date are business time and whose valid_from and valid_to are system time, alongside status and source_file_id. Two files covering overlapping populations can be in flight at once. Design the loader's backpressure, the bitemporal write, and the invalidation fan-out to the eligibility cache and to claims already adjudicated against the now-terminated coverage.
Approach
- Never update a coverage_span row. A retroactive termination closes the current row by setting valid_to to now and inserts a new row with the same effective_date, the new termination_date, and valid_from set to now. Both questions then stay answerable: current truth for a past service date filters valid_to = 'infinity' and ranges on business time, while what the system believed on a past date filters valid_from <= that instant < valid_to.
- Index for the two axes separately rather than hoping one structure serves both. A btree on (enterprise_person_id, effective_date DESC) partial on valid_to = 'infinity' serves the hot current-truth path; the as-of-system-time path is rare and analytical and can afford a wider scan. A single range index covering both usually makes the common query worse to make the rare one tidier.
- Bound the loader instead of running it flat out: chunk into batches of a few thousand rows with a committed checkpoint offset per file, and pace on a downstream signal — replication lag or invalidation queue depth — rather than a fixed sleep. Two million rows written as fast as the database accepts them is how a weekly file becomes a replica-lag incident at 03:00, and the checkpoint is what makes a mid-file crash resumable instead of a full re-run.
- Serialise per person rather than per file. Two overlapping files must not interleave versions for one member, so key the work queue on enterprise_person_id and let files proceed concurrently across different members; order within a person's partition by the file's assertion time, and keep source_file_id so a bad file is attributable and reversible as a set.
- Fan the consequences out as work, not as a cache flush. Publish the changed enterprise_person_ids so the eligibility cache drops exactly those keys, and enqueue the claim identifiers whose service dates now fall outside coverage. Those claims need reversal and re-adjudication, which touches accumulators, so this is a throttled backlog with its own ordering rather than a synchronous cascade at load time.
- Measure the blast radius before it lands: a dry-run pass counting rows whose termination precedes the file's receipt date, and the claims each would affect, turns 'we loaded the file' into a reviewed number. A file retroactively terminating forty thousand members is either a real event or a sender bug, and you want to know which before the reversals run.
Worked solution 45 min
- Write the close-and-insert pair for a retroactive termination, then write the two queries — current truth for a past service date, and belief as of a past instant — and run both against the result.
- Write the chunked loader loop with its checkpoint and the downstream signal it paces on, and state the batch size and what it is derived from.
- Define the per-person work queue key and show what happens when two overlapping files touch the same member.
- Write the fan-out payload and the two consumers, and state the throttle on the claims reprocessing backlog.
- Write the dry-run query that counts retroactively terminated members and the claims they affect.
Follow-up
- The sender resends last week's file unchanged. What does the loader write, and how do you prove nothing changed?
- One file terminates a coverage that a later file reinstates with the same effective date. What does the current-truth query return while both are mid-load?
Gateway instances OOM every five days with flat traffic
Interoperability gateway instances are OOM-killed with exit 137 every five to six days. Resident memory grows about 400MB a day per instance and never falls; restarting resets it. Message throughput, connection count and partner mix are unchanged over that period. The gateway keeps an in-process set of recently seen idempotency keys — (sending facility, sending application, message control ID, event timestamp) — in front of the durable ledger. Give the ordered investigation and say what evidence would rule the idempotency cache out.
Approach
- Establish that this is a retained-object leak before profiling. Compare resident memory with live heap measured immediately after a forced collection, sampled daily. Resident memory rising while post-collection live heap stays flat points at allocator fragmentation, off-heap or native buffers, or thread stacks, and a heap dump will implicate the wrong object. Rising post-collection live heap is a genuine leak.
- Find what the growth is linear in. Plot daily growth against messages processed, connections accepted and wall-clock hours across instances carrying different traffic. Proportional to messages means something is retained per message; proportional to connections means per-connection state is not released on abnormal close, such as a half-open socket whose FIN never arrives.
- Diff two heap dumps taken six hours apart on the same instance, sorted by retained size, and identify the dominator. An unbounded set or map shows up as one root holding millions of small entries. This is a five-minute answer once you have the dumps, which is precisely why the first two steps exist: they tell you whether the dump can answer the question at all.
- Check the idempotency cache directly against arithmetic rather than suspicion. At single-digit millions of messages a day and a key of roughly 80 bytes plus per-entry overhead, an unevicted set grows by hundreds of megabytes a day, which matches the observed 400MB. A live gauge of its entry count that stays flat is the evidence that rules it out; a gauge tracking messages processed convicts it.
- Fix and restore the invariant: bound the cache by size or by a time window, and keep the durable unique constraint as the authority. An in-process set is a latency optimisation and cannot be the correctness mechanism, because it does not survive a restart and is not shared across instances — so a replay right after a deploy would bypass it entirely.
- Verify over 48 hours that post-collection live heap is flat, and alert on the cache's entry-count gauge rather than on resident memory, which only tells you after the growth has already happened.
Follow-up
- How long must the time window be? Tie the number to the sender's replay behaviour after an interface restart and to how far back the broker redelivers.
- If growth had tracked connections instead of messages, what would you look at first, and how would a half-open MLLP connection show up in the socket table?
Day one measures instead of guessing, under a fixed rubric, and the remaining hours are allocated in proportion to the gaps before any studying begins. The allocation is deliberately not renegotiated midweek, because the area that feels worst on day three is usually the one that is moving.
Prepare, practise & reflect
One practical outcome each day. Spend longer where you need it.
0 / 7 done01Diagnostic, scored before you study anything
- Sit a 110-minute diagnostic in four blocks: forty-five minutes on two coding problems, twenty-five on one design prompt taken to interface and data model, twenty of short-answer fundamentals, and twenty delivering two behavioural answers aloud.
- Score each block from 0 to 3 on a fixed rubric where 3 is correct and fluent, 2 is correct but slow or prompted, 1 is partially correct and 0 is stuck, grading the artifact rather than how the attempt felt.
- Allocate days two to five in proportion to 3 minus each block's score, write the allocation down, and commit to leaving it alone.
Deliverable: A scored rubric and a fixed hour allocation for the rest of the week.
Practice prompt ↗Practice prompt ↗Worked solution ↗02Largest gap: find the boundary rather than the subject
- Split the weakest area into named sub-skills and rate each separately. For coding those are restating the problem, choosing the structure, stating the invariant, turning the invariant into loop bounds, handling empty and single-element input, and accounting for complexity out loud.
- Attempt three items positioned just above where the rating drops off, and for each write the first move you failed to make.
- Re-attempt one of them from blank four hours later with nothing open.
Deliverable: A sub-skill map with the two blocking sub-skills circled.
Practice prompt ↗Practice prompt ↗03Drill the blocking sub-skill by repeating the shape
- Do eight short repetitions of the same shape rather than eight different problems, so what gets practised is the pattern and not the puzzle.
- State the rule you now hold in one sentence, then test it against a case built to break it, a sliding window over an array containing negative values, or a cache-aside read path whose invalidation message is dropped.
- Have someone else read your one-sentence rule and find the precondition you left out.
Deliverable: One rule statement with its preconditions attached and one counterexample that would have caught the incomplete version.
Practice prompt ↗Practice prompt ↗04Second gap, plus maintenance on the strongest area
- Run the same sub-skill decomposition on the second-largest gap in half the time.
- Spend twenty-five timed minutes on the block you scored highest, choosing the hardest item you can still finish rather than a warm-up.
- Write whether each area fails you on recall, on setup, or on execution, and set the fix accordingly: repetition for recall, a written checklist for setup, timed work for execution.
Deliverable: A second sub-skill map plus a one-line failure diagnosis for each area.
Practice prompt ↗Practice prompt ↗Worked solution ↗05The gap that is not a skill
- Record one technical and one behavioural answer, then count two things in the playback: seconds before your first clarifying question, and sentences you began without knowing where they would end.
- Practise saying that you do not know, followed by how you would find out, without letting it soften into a guess, and practise stating a complexity or an estimate before being asked for it.
- Redeliver one answer under a hard ninety-second cap, which forces structure ahead of detail.
Deliverable: Two recordings with a counted reduction in time-to-first-question.
Practice prompt ↗Practice prompt ↗06Retest under day-one conditions
- Sit the same 110-minute structure with new prompts of comparable difficulty and score it on the identical rubric.
- For any block that did not move, change the method rather than adding hours: a block stuck at 1 usually means the practice was too varied, not too short.
- Write down which single block you would still lose the offer on.
Deliverable: A second scored rubric placed beside the first, with one named remaining risk.
Practice prompt ↗07Full loop under interview conditions
- Run a sixty-minute mock over the two blocks that moved least, with an interviewer briefed to interrupt and change direction mid-answer.
- Write the recovery script for going blank: restate the question, state your assumption, name the first thing you would check.
- Say every rule from the week aloud without reading it, and cut any you cannot state in a single sentence, since a rule you have to reconstruct mid-answer will not survive an interruption.
Deliverable: A one-page card holding the recovery script and only the rules you could state from memory.
