HR interview and phone interview There was going to be a 3rd interview in person in the company but they decided to close the position because there was a problem in the team.

First stage was a numerical test done online within a short period of time. Mostly simply math questions, and only the last couple of questions were more challenging. After 2 weeks approximately, they got back, and second stage was an interview with the HR personnel over skype with the usual interview questions.
