Tata Consultancy Services Senior Developer - UI interview questions

I went to TCS, noida sector 62 for the interview. First round was a telephonic interview. Interviewer asked many questions on javascript and ES6 and on cross browser compatibility to check the basic concepts. I got rejected in the first round.

Two technical rounds and the HR calls to ask about salary. After clearing technical round HR called me, I will send you offer letter if you can come on the same salary what it was in your previous company.
