Altair Engineering Software Development Engineer interview questions

First there is a technical written exam if qualified then Group-Discussion if qualified then it is followed by personal-interview. The technical exam is relatively easy, it consists of mostly physics and dynamics based questions. The GD is mostly related to new and innovative ideas

I applied on job portal and then HR shortlisted my profile for interview. It included Technical + HR round altogether. Interview was easy. They asked simple c++ questions. It took only 20 mins.
