ZeMoSo Backend Engineer (Java) interview questions

4 rounds 1) L1 technical round - Java basic, spring boot, concurrency and J8 programming 2) L2 tech stack knowledge with System Design 3) L3 DSA and System Design Round 4) HR Round on Salary Negotiation

The interview happened through an Third party application. The person who interviewed was sitting in some hotel and taking an interview for me. And the place was too noisy. Most of the time not able to get what he is trying to ask. Also his internet was soo unstable, once the interviewer goes out of the application. I was also pushed out of it. Again I have to connect to the application. If the interviewer is not available, interview can be rescheduled. But should not waste the time doing like this. One of the worst interview experience.
