I got contacted by Yota's HR directly, had a brief telephone interview, then agreed on scheduling a Skype call. The company was surveying the market in search of someone pro-active and enthusiastic (even at the cost of required experience).
The interview itself was quite ordinary - few questions about my experience, achievements, why I wanted to join the company,etc.
Then received an email the following day saying that I might not be the candidate they are looking for and that was it.
