A rigorous hiring process. First round was a written test. There was a choice between Java/C paper. The questions were of average difficulty. The paper consisted of C/Java questions along with some aptitude questions. Nearly 50 candidates appeared for it at their Gurgaon office. About 5-10 candidates were shortlisted after the first round and were called in the following week for interviews on different dates. There were a number of rounds that were completed in one day. So, the Second round was a written test of C (since I had appeared for C in the first round). It contained some common coding questions, output questions and more of theoretical questions. Third round was technical interview by two people. They asked questions over the answers that I had written in the test paper. Fourth,Fifth and Sixth rounds were also technical interviews, one on one. Seventh round was more of an HR round. Thereafter I left, and later got a call from the HR saying that I was selected, with immediate joining.
