I was short listed through HackWithInfy contest. It is double round contest followed by remote interview. In the second round you will be monitored through web cam. Interview was just only 15 - 20 min. If you have cleared the interview round there will be telephone interview to the selected candidates to confirm their choice of preference of work location. In telephonic interview there is no shortlisting. If you are invited to a telephonic interview, it is sure you are into the company as System Engineer Specialist (5 LPA). Even some people who are mot invited for telephonic interview are also offered with similar job(System Engineer) will another salary package (3.6 LPA).
