The Newgen Software interview process

Newgen Software candidates report 3 rounds over 3-5 weeks. The stages below are what candidates describe, not a published process.

Online Screening Tests

Candidates undergo comprehensive online tests to assess their technical capabilities.

  • Behavioral and HR evaluations assess psychological fit and communication skills
  • Depth in Java

How to prepare

  • Prepare three examples from your own work, each with a decision you made and an outcome you can quantify.
  • Re-read the description of the behavioral evaluation above and write down what you would ask to confirm before it.

Where candidates lose points

Do Not Argue with the Panel

You may occasionally encounter an interviewer who is rigid or highly focused on bookish, theoretical definitions. If a disagreement arises regarding a coding solution or concept, remain polite, explain your logic calmly, and avoid getting into defensive arguments. Professionalism is heavily evaluated.

Be Consistent in the Personality Rounds

In both the written psychometric sheet and the verbal HR discussions, keep your answers aligned. The company looks for dependable, stable individuals, and conflicting answers across different rounds can lead to sudden rejections.

Draft Professional Emails Carefully

Some interview drives include a short email-writing or letter-writing test. Treat this seriously. Ensure your grammar is correct, your tone is professional, and you structure the email clearly, as this directly reflects your business communication skills.

One log partition stops advancing while the others drain

Easy · poison message · head-of-line blocking · consumer lag

Search results for a subset of tenants are hours stale; the rest are current. The projection consumer reports lag of zero on 15 of 16 partitions and 400,000 on one. Its error rate is flat and its CPU is idle. outbox_event has no pending rows older than a second, so the relay has published everything it holds. Identify the mechanism, give the ordered checks, and state what you do in the first ten minutes versus what you change permanently.

Approach

  1. Read the lag distribution first. A slow consumer lags everywhere; zero on fifteen partitions and 400,000 on one is not throughput. Idle CPU on the stuck partition means the consumer is not advancing its offset at all, which points at one message it cannot get past rather than at a rate problem.
  2. Exonerate the producer before touching the consumer. No pending outbox rows older than a second means the relay published, so the event exists in the log. This separates never sent from sent and never applied, which are different code paths and usually different owners.
  3. Read the message at the stuck offset and the handler's log lines for its event_id. A flat error rate with no progress has two explanations and you must distinguish them: the handler is throwing and the retry loop is swallowing it, or the handler is blocking on something and never returning. Idle CPU with no error lines favours the second.
  4. Mitigate before diagnosing further. Move the offending event to a dead-letter store and commit the offset past it. Adding consumers does nothing here, because a partition is consumed by exactly one member of the group, and the blast radius is every aggregate hashed to that partition, not only the aggregate that produced the bad event.

Follow-up

  • The dead-lettered event carried aggregate_version 7 and the projection had applied 6. What must the replay do differently if 8 and 9 landed in the meantime?
  • How do you show staleness to the user while the partition is behind, given the API already returns the projection's watermark?
