I applied through an employee referral. I interviewed at Roscongress Foundation (Saint Petersburg, Sankt-Peterburg) in May 2015
Interview
It was very quick. The head of the department and senior manager were the "panel committee", but it was rather informal and easy-going especially when they see that you're really driven by the idea of the events the company is organizing.
Interview questions [1]
Question 1
