If they offer you a position in USA for a contract better get away from the offer. They come to you only to satisfy their clients and once your h1b meets an RFE they don't even care for it. the management is done by under rated programme managers. They won't pick your calls and don't respond to your emails. In my 10 years of experience i heard about so many companies none of them competes with this company in its stupidity

It had 2 round of technical interview mainly focusing on your core to assess your knowledge and understanding of work. Overall it was normal interview as difficulty level it was moderate.
