Tata Consultancy Services Devops Engineer interview questions

It is a good experience but I have attended interviews through Consultancy, So I have cleared the interview But it is overall a good experience, I always dreamed of Joining an MNC like TCS but I didn't get an opportunity this time but sooner or later I will get it.

First there was technical round and then HR.I cleared the technical round and the interviewer told me that you will be getting call from HR for salary discussion.I got a call from HR after 3 days and we had a discussion regarding salary.HR told me that they will contact me later and didn't even call me till now.When I am trying to reach them for the updates they are not even picking up the call. This is very unprofessional and disrespectful behaviour from TCS HR team.
