I waited for about 30 mins after hr called me and asked to take seat, after that 2 person came in to take interview, they were such nice person, the first round went very well, they were helping me to tell the answer at some point where I was stuck. And in 2nd round some senior person took interview, he was also very calm and was asking conceptual question and some coding stuff. overall experience was good. Also learned some new things. I really wanted to work with them, but was unable to clear second round.
