Three stages of interview two tech round and one hr round mostly with technical only all the questions are relatively to position available for the company, each round conducted through phone in interview

Three interviews. The first interview was on the phone with HR to see if I was interested. The second interview was on the phone with a developer. This interview was a technical interview. The third interview was in-person and involved more hands-on technical questions. I was asked to write on the white board. Both Java-based and C questions. I don't know C though, so I struggled with those questions. Make sure you know data structures for the technical interviews.
