First round: Technical, I cleared
Second round: Aptitude, I cleared
Technical interview: cleared
HR interview: cleared
and last interview with the vc of the company in which I thought only salary and some basic questions will be asked but she started asking me technical, numerical and logical questions, some questions from B.E. apart from Piping and Equipment. At last, she took another test of me and after the test, they simply told me to go without giving any information about whether I'm selected or not.
