Had a call with HR, then with another HR, after had a meeting with the boss. Overall it was very quick and not hard at all, simply asked me questions on the logic and how could I approach the project, got the offer at the end.

Interview was done via phone call and Skype. Interview process was pretty straightforward, the hiring manager was curious about my previous experiences, education and vision for the project that I was going to participate in (ideas on vertical market research). Overall, nothing too extreme, the process was not stressful, managers were supportive.
