After I submitted the CV, it took a while to get the phone call from the HR. We then had about 30 min of phone interview, generally about my interest in the company. Then, I got a call to come to an onsite interview and prepare some presentation on my previous project. Basically, they asked me about the project I did in my university and some basic technical questions.
