Karat round - very poorly organised and fast paced, The interviewer had list of questions, system design question- he did asked list on question on top of that system design(EV charging), Leetcode style thrilling teleporter to solve under 20 mintues, he said its very easy but it was hard hash maps +BFS problem. system design also he did not are much.

1st round was technical in-depth where they asked me questions about middleware, networking, TCP, TLS, Certificates and Big-IP F5 devices (device upgrades and configuration of F5 devices). I was able to answer most of the questions really well. 2nd round of technical interview was in fact a techno-managerial round, which happened with the director of that department, which went pretty well as well.

2 Technical, 1 Managerial, 1 bar raiser round. First round was coding round. I got the call as part of college placement process. The coding round was eliminatory round. I completed the coding round and after 2-3 days completed rest of rounds in single day

Screening Round: Only scenario-based questions were asked, mostly hypothetical. I was rejected in the screening round itself. The interviewer was friendly, professional, and maintained a positive attitude throughout the discussion.

The first round was technical screening round with the recruiter, then the second round was a technical one where I performed well and it was mainly related to AI and RAG.
