PracHub editorial advice for the preparation topics above.
Clarify Expectations Early
Ask your recruiter for a detailed outline of each interview stage, including the format of the technical rounds and the specific technologies you will be evaluated on.
Master Your Resume
Be prepared to discuss every project, technology, and methodology listed on your resume in detail. Interviewers frequently ask deep-dive questions about your past hands-on experiences.
Practice Live Debugging
Since some teams evaluate candidates by presenting a buggy code snippet, practice reading and troubleshooting code quickly. Focus on identifying logical errors, edge cases, and performance bottlenecks.
Showcase Healthcare Awareness
While deep healthcare domain knowledge is not always required, demonstrating an understanding of data security, compliance, and the importance of user-centric digital health solutions will highly impress your interviewers.
Turn Your Camera On
For virtual interviews, ensure your camera is on, your workspace is professional, and your audio is clear. Showing engagement and maintaining good virtual eye contact helps build rapport with the panel.

Every query on one table stalls for forty seconds mid-deploy
During a release on PostgreSQL, every query touching resource times out for about 40 seconds and then recovers with no intervention. The release ran one migration, ALTER TABLE resource ADD COLUMN archived_reason TEXT, and the migration log shows it completing in 6 ms. Unrelated tables showed no change in error rate. Explain how a 6 ms statement caused a 40-second stall, give the ordered checks you would run on a live system to confirm it, and give the migration procedure that prevents a repeat.
Approach
- Separate the statement's duration from the lock's duration. ADD COLUMN with no default is a catalogue-only change and genuinely runs in milliseconds, but it requires ACCESS EXCLUSIVE, and it cannot acquire that until every transaction already touching the table has finished.
- Account for the queueing, which is the part that surprises people. A lock request that is waiting blocks later requests for conflicting modes behind it rather than letting them overtake, so one long-open transaction holds the DDL and the DDL holds all the traffic. The stall length is set by the longest open transaction, not by the size of the change.
- Confirm on a live system in this order: pg_stat_activity for that table ordered by xact_start, looking for the oldest transaction and specifically for state = idle in transaction; then pg_locks where granted = false to find the waiter; then join them on pid to name blocker and blocked. pg_blocking_pids() does that join for you and is the fastest single call.
- Prevent rather than merely time it better. Set lock_timeout to a second or two on the migration session so the DDL abandons the queue after a bounded wait and is retried, instead of holding it for as long as the oldest transaction lives. Be exact about what that buys: queries arriving during the wait still queue behind the pending ACCESS EXCLUSIVE request, so each attempt costs them up to one lock_timeout of added latency. The outage goes from 40 seconds to about one second per attempt, not to zero. Also run migrations away from deploy-time peaks, and put a statement timeout and an idle-in-transaction timeout on the analytics role that opens the long transactions.
Follow-up
- The same release also wants NOT NULL on that column. What is the sequence that gets there without a long lock?
- Your lock_timeout retry fails ten times in a row because the analytics transaction is always open. What do you change?
