First of all, there was an online test to check my technical skills. No coding task, but only theory and calculating the program output. A few days after that, there was a quick mobile call out of nowhere from an HR, asking a few very basic theory questions and a small talk to check level of my English. After that I was invited to a technical interview. Since it was an interview only for internship, it was pretty easy. There were 2 tech specialists, who was asking theory questions. Whole interview took about 30 minutes.
