Informal interview, professional but friendly atmosphere. Communication was smooth, invitation via email, prompt responses, flexibility in setting the interview date. The process included a test and three rounds of interviews.

I've applied via their website and did two rounds of interviews. The first one was with someone from the HR and then the second one with a stakeholder. The first one, HR was late 15 minutes and started the meeting telling me the vacancy was not available anymore - they decided not to hire someone. But them they suggested I applied to a senior position... and I agreed. They schedule the call in the middle of my vacations, and I connected from my phone. Had an okay interaction with the stakeholder for 1h or more, simple questions, nothing complex. I understood this was a behaviour interview, as the person was not from my field. They wrote me a couple of days later saying they wouldn't follow with my process, although I was a cultural fit - they wanted someone with "more experience in complex projects" with sounded absurd at that point, when they didn't evaluate it. This plus the sloppiness of the whole process let me quite disappointed.
