I applied through a staffing agency.

First Round: HR Screening on - do you know spring, hibernate, why do you want to change your current company etc etc Round 2: Hackerrank test design to test your Java- Spring knowledge(set up and fix spring configuration issues ) with few subjective questions like Design a system etc simple queries. Round 3: Video interview on past experience + DSA + java live coding + LLD + HLD (they wanted to cover all of it in 60 minutes) The interviewer was not much experienced and did not understand complexity analysis well.

Probably a newbie in dsa who read thing and asked the same in the interview without understanding the underlying concept. Overall it was a very unorganised interview and waste of time.

Java

HLD

Spring

why Kafka and not kinesis etc etc
