EPAM Systems Tech Lead interview questions

There were total 3 rounds. First one was about 1.5 hours and the next 2 we're about 1 hour. They asked me a lot of questions and I described them pretty well. All 3 were technical rounds with a lot of coding problems. After that the recruiter said my score is very good but they didn't hear from the upper management for my status. It's still put on hold. So I suggest if you are asking higher salary don't waste your time in the interview process with epam. If you can't pay what I am asking then why do you even call for interview?
