I applied online. The process took 2 weeks. I interviewed at Moscow Consulting Group (Moscow, Moskva) in Nov 2016
Interview
First, you should apply online and find a person from your network who knows people from the firm to put a word for you to pass the screening.
Second, they invite you to problem solving test (PST) in their office. It is similar to McKinsey tests. 60 minutes, 3 cases, 26 questions.
Third, if you pass, the do background check and contact your former colleagues and employer to get a feedback on you.
Then, you will be invited for in-person interview with one or two partners. I had one 2 hours interview, 2 cases (45 min) each and fit interview.
They told me feedback straight after the final case interview.
