I applied through other source. The process took 3 weeks. I interviewed at Gazprom Neft (Saint Petersburg, Sankt-Peterburg) in Mar 2017
Interview
It was a lovely meeting at the office. They asked me about my CV, how many hours I can work. Since the internship was unpaid, they didn't have too many applications, so it was not hard interview at all
