It was a very well-organized and difficult interview. The interview process had 3 rounds: 2 technical and then 1 followed by a managerial round. After the managerial round, I directly got a call from HR stating that I have been shortlisted and they will be sharing the salary number really soon.

• Method overriding: why, when, how?
