After a couple of weeks from applying, I received an email about scheduling a phone/Skype interview. Couple days after the interview they requested a 1:1 interview at their HQ in Cambridge. There was only one test, where I had to play a really old game on the Playstation 2 and find and submit bugs. This process lasted an 1 hour. Afterwards, the recruiter and QA Lead and I had a chat about the process and my skills.
