As a Software Engineer at Paramount, you will build and scale the digital infrastructure that powers world-class entertainment, streaming, and media products consumed by millions globally. You will contribute to high-visibility initiatives spanning Connected TV (CTV) platforms, web and mobile applications, and robust backend microservices. Your code directly impacts how users stream live sports, blockbuster movies, and hit television series across a massive distributed ecosystem. The role demands a balance of creative problem-solving and rigorous engineering discipline. You will collaborate closely with product managers, designers, and fellow engineers to architect systems capable of handling massive peak traffic loads with low latency and high reliability. Whether you are optimizing video delivery pipelines, integrating modern frontend frameworks, or designing scalable cloud-native architectures, your work drives the core digital business of Paramount. Expect a fast-paced, collaborative environment where technical excellence meets media innovation. While the technical stacks vary across teams—ranging from modern web frameworks to specialized media streaming technologies—the core mission remains consistent: delivering seamless, engaging entertainment experiences. Success in this role requires both deep technical proficiency and the ability to navigate cross-functional projects across multiple time zones.

PracHub editorial advice for the preparation topics above.
Communicate your thought process aloud
Never code in silence. Interviewers want to understand how you reason through edge cases, debug errors, and pivot when your initial approach hits a roadblock.
Brush up on computer science fundamentals
Do not skip core concepts like Big O notation, basic data structures, and object-oriented design principles, as theoretical questions frequently appear in technical rounds.
Be ready to discuss your resume deeply
Expect interviewers to pick specific projects from your history and ask probing questions about your architectural choices, challenges faced, and measurable outcomes.
Prepare thoughtful questions for your interviewers
Use the time at the end of your sessions to ask about team tech stacks, deployment pipelines, and how engineering priorities are balanced with product roadmaps.

Explain why the owner filter ignores the listing index
The only index on resource is (tenant_id, status, updated_at DESC, resource_id DESC). A new endpoint returns one user's resources across all statuses, newest created first: WHERE tenant_id = $1 AND owner_user_id = $2 ORDER BY created_at DESC LIMIT 20. On a tenant with 2M rows it takes 900 ms and EXPLAIN shows a sort above a large scan. Explain precisely why the existing index cannot serve it, give the index that can, and state which of these the new index still will not help: owner_user_id alone across tenants; the same query ordered by updated_at. PostgreSQL 16.
Approach
- Separate the two jobs an index does. For filtering, a composite btree is seekable only on a left prefix, so with no predicate on status the scan can at best range over tenant_id and test owner_user_id per row; PostgreSQL 16 has no btree skip scan to jump the unconstrained column.
- For ordering, the index is sorted by (status, updated_at) within a tenant and not by created_at, so the LIMIT cannot stop early: every matching row is read and then sorted. That is the 'Sort Method: top-N heapsort' line, and it is why the plan reads 2M rows to answer with 20.
- Derive the replacement from the access path — equality, equality, then the ordering column: CREATE INDEX CONCURRENTLY ON resource (tenant_id, owner_user_id, created_at DESC). The scan seeks to the (tenant, owner) range and walks 20 entries in order, so the Sort node disappears along with the row-read.
- Treat INCLUDE (title, status) as conditional, not free. An index-only scan still visits the heap for any row whose page is not marked all-visible, so on a table taking 1.2k writes/second the win depends on autovacuum keeping the visibility map current, and the wider index costs more on every insert.
Follow-up
- 90% of rows are status='active'. Would a partial index WHERE status = 'active' change your answer, and for which of the three queries?
- A dashboard runs this for 40 owners in one page load. What changes about the design?
Hold a per-tenant active cap against concurrent creates
A tenant on the standard plan may hold at most 50 resources with status='active'. The create handler runs SELECT count(*) FROM resource WHERE tenant_id = $1 AND status = 'active', compares to 50, then inserts. Two creates arrive 3 ms apart on different instances and the tenant lands at 51. Name the anomaly, say whether PostgreSQL 16 READ COMMITTED or REPEATABLE READ prevents it and why, then give an implementation that holds the cap at READ COMMITTED with the exact statements. Finally, say what changes when the cap is 'at most one running export per tenant' on job_run.
Approach
- Name it: write skew. The two transactions read an overlapping set and write disjoint rows, so there is no row-level conflict for the engine to detect and each commit is individually legal.
- Rule out the levels precisely. READ COMMITTED takes a fresh snapshot per statement and takes no lock on the counted rows, so both see 49. PostgreSQL's REPEATABLE READ is snapshot isolation: it removes non-repeatable reads and phantoms within the snapshot but still admits write skew, because the anomaly is not a re-read of a changed row, it is a read of a set that a concurrent transaction invalidates. Only SERIALIZABLE closes it, by tracking the read dependency and aborting one transaction with SQLSTATE 40001 — a guarantee that exists only if the application re-runs the whole transaction from the read.
- Convert the set predicate into a single-row conflict: keep tenant.active_resource_count and run UPDATE tenant SET active_resource_count = active_resource_count + 1 WHERE tenant_id = $1 AND active_resource_count < 50 in the same transaction as the INSERT. Zero affected rows is the cap, returned as 409. The row lock serialises the decision at any isolation level, and contention is bounded to one tenant's row — which is also the fair-scheduling unit, unlike a global counter that would convoy every tenant behind one row.
- State the cost you just took on: a counter is a second source of truth that can drift, so every path that changes status must adjust it inside the same transaction, and a periodic reconciliation has to exist, with resource_revision as the authority for what the count should have been.
Follow-up
- A resource moves from archived back to active. Which statements change, and what breaks if the counter update and the status change land in different transactions?
- The cap becomes plan-dependent and a plan can change mid-month. Where does the number 50 live, and who reads it?
