I applied through an employee referral. The process took 1 week. I interviewed at Wargaming (Kyiv, Kyiv) in Sept 2017
Interview
It was two-step interview. The first one: a phone call with an HR person. The scond step: on-sight interview with a lead and an HR. No home task was given, but the interview did list for quite a while.
