I got contacted by the person in charge for building the local team ("I need to hire 100 people in 3 years"). Even though it was clear that I did not have experience in their specific tech stack, he wrote that at the end of the day a developer is a developer and that would not be a problem. At the on-site interview, I talked to him - a very nice and friendly person, and to a HR representative from the headquarters, who candidly admitted that they not only want to have employees from different countries for a diversified environment - which is good - but also often relocate them from abroad, so "they have to leave their families and friends, and we can become their family, and they will spend with us their free time" - which sounds much creepier and manipulative than she probably intended. A couple of hours after the interview, I got an email saying that they preferred other candidates with more relevant experience. So much for a developer is a developer, but fair enough.

It started with a one-on-one, followed by a challenge and after some time I had the most strange interview questions. They may be a great company but aren't NASA. It seems that don't give any value to good code, design patterns etc... They just have interest in dev-ops and technical stuff.
