The interview process is extremely weird and complete rubbish.

The interview was of 3 stages:

1. Stage 1 coding round (No technical questions asked)
2. Stage 2 coding round (No technical questions asked)
3. Stage 3, a 3 hr round interview with two interviewers and again 2 coding rounds in that and hardly a technical question. You also do a presentation.

No questions asked on design, no algorithm-based questions, no questions on performance tuning, no questions on frameworks. This is extremely weird – just coding rounds, and that too some concurrency which you solve through with basic constructs like synchronized, wait, and notify.

In the last coding round, this developer asks you to write a lexer with too many ifs and buts, because he might have encountered it in production, and he expects you to write it down in 1 hr and has a serious communication problem. His question also took me by surprise. Eventually, in the rejection, they cited coding issues, and I am wondering how they approved the first two rounds of my coding.

No HR rounds, nothing, and the 3rd stage is the final one. It's an extremely unbalanced interview process.

1. Implement a lexer.
2. Threads (Producer-consumer type problems mainly).
