After applying online I got an email from the HR to schedule an online (Skype) interview for the next days with herself. On the interview she made very clear how the whole process works and asked some basic questions. It took around 30 minutes. On the same week was scheduled an interview with someone from the technical team, which took 1 hour. After passing that one was schedule for the next week the last interview with the CTO, and this one took 1 hour and a half. He told me that I would expect an email the next days with the result. Some days after that I got an email asking to schedule a final call to discuss my expectations. The whole process was very clear and organized.
