I applied online. The process took 3 weeks. I interviewed at Yandex (Saint Petersburg, Sankt-Peterburg) in Feb 2017
Interview
One week after online task submission I was invited to on-board interview. Pleasant overall but 3 hours of technical interviews in a row is not the best experience I had. In my opinion 5 minute breaks are too small, 15 would be sufficient.
