I applied through a referral in Pune. First interview was telephonic. They asked about my resume and projects that I've done. There were some basic concepts about pointers and c programming. What I liked about the interview is, the interviewer was more interested in what I want in that position, what type of work I like and tried to see if I fit in. Second round was on site round. They asked few data structure questions. Like LCA, tree based algos. Operating system and networking concepts. Third round was only focused on the work I did and design, architecture related. Interviewers were really friendly and professional. After the interviews i did not receive any result from them. Contacted them and they said applications is on hold. Fair enough. Few days later, it was still on hold. I interviewed in October and till February it was on hold. They did not inform me until when the application is on hold. Which seems unprofessional to me. Should I wait for a month / year / decade? I finally gave up. They have a very nice team and product to work on and I was really interested in working there. Sadly because of poor management, operations and bad communication, i could not join.

First round was Hackerearth MCQ and Coding test, with questions on OS, RTOS, CN. No aptitude questions. Followed by the qualification test there were 3 rounds of technical interviews and a HR round. I did not get shortlisted after the first interview.
