First round started 1hr late and was related to architecture discussions. It was fun and we had a healthy discussion. I waited for 2.5 hrs after that for second round. But the guy in 2nd round was not so great. We discussed problem, I gave him a solution and he asked me to write down the code on a paper and then there was a tree based question which I could not answer because I was not prepared for it. They sent me back after that without giving a proper feedback. Overall it was a BAD experience with them and I am disappointed.
