Interviewing process took a while, initially you'll deal with HR contractors. You'll typically have to pass a short technical questionnaire over the phone with somebody from HR who will make some questions, they actually don't understand the questions but they are easy and focused enough that they require a spot on answer. Easy. Then you'll have 2 or 3 interviews via skype with more coding and challenging questions. The face to face interview will take around half a day and you'll be interviewed by 3 or 5 people (depending on the team). lots of technical questions mainly algorithms and pseudo coding.
