There were three stages of the selection process. The initial interview was done over skype with two HR representatives. It lasted around 40 minutes, the questions were standard job interview stuff. They also explained job details like salary and work hours. After that, I was invited to do a test which consisted of editing a text based on the directions they gave you. The test is an hour long and not too difficult. The last stage was a very brief interview with a group leader. The whole process was pleasant and easy, all my questions were answered and the interviewers were friendly and polite. It took around two months from the initial interview invitation to receiving an offer, so the whole selection process is a little long.
