Had a meeting with chairmen director. Pleasant conversation and he was open about which division I should work at. They are super flexible about interns, and offer internship position, though internship is not paid it is a valuable experience anyways.
I applied through a recruiter. The process took 1 week. I interviewed at Sberbank
Interview

Discuss your experience and technologies. Interviewer describes the projects and team where you will be working. Then you will discuss the format of the internship and the hourly load.
