Summary
Interview consisted of two rounds focusing on system design and concurrency. The experience was negatively impacted by poor communication and time management.
How it went
Round 1: A detailed problem statement shared on hackerrank. It boiled down to writing code for a circuit breaker like system where there are plethora of microservices involved.
After the code completion, thread safety, http status codes and java concurrency solutions were discussed.
Round 2: Some shares selling event related question. System design.
Hard to decrypt the accent of the interviewers so had to ask them to repeat themselves frequently.
I was not informed of hard stop before 10 mins. of the interview. I wasn't allowed to complete my solution and was stopped in between and wasn't informed of this time check beforehand.
Waste of time!!
