Technical knowledge is must needed,as the company works for Banks and Finance. The Interview is little tough they ask everything about you mentioned in resume. So you must know about it.

I was referred by a friend, Interview process was easy, after 2 technical and manager rounds, manager discussed the salary if it is negotiable, when I had quoted the same salary in the beginning of the interview, I had to go in person to office for the interview and the manager says we don’t have budget. They just played around and wasted my time
