Applied in their website. Got a call from HR. Had a telephonic interview. Asked about projects, basic questions about time complexities. Given a array containing numbers from 1 to n, one number is missing, one number is repeating. Gave the answer in O(nlogN), satisfied. Next day, HR called me and sent a coding challeneg. Did that, later got an invitation for F2F in their office. First round is went fine. Later they gave me a problem of File Systems, didn't do it. All expenses reimbursed. Later got call from the person who interviewed me in the first round, asking my expected package, said 7.5, he said can't give that much, I said 7, there is no response from their side. But, overall I like their culture all are from BITS (everyone speaks telugu). Special Mention, Ashwin who interview me in F2F, he is a cool guy, I didn't felt it's an interview, a typical geek discussion. He helped me so much.
