I met several members of the team, in different occasions. Being abroad, I did half of my interviews remotely. After the first 4 ones, they organized an onsite interview for me, taking care of transport and accomodation in a very professional way.
I probably didn't perform as they expected from the management point of view during the co-planning session onsite, but since I seemed a good tecnical/culture fit for the people that interviewed me until that point (about 10 of them), they had me talking with the mobility team to start planning about moving there.
Everybody seemed pretty happy/satisfied, and I had to do one last "standard, final fit" interviw with the CTO and one of the Principal Engineers.
People from the Talent team of the company gave me very useful advice about how should I have prepared for this final interview, and I really appreciated it. I followed the instructions but, in the end, it wasn't enough:
Since the beginning of the final fit interview, I had the feeling that the Principal engineer wanted to turn me down for no particular reason at all. He asked me about some decisions I made 7 years ago about starting my previous company, which I told I was going to leave in order to join Improbable, and basically wanted to force me to admit that "starting my own company instead of joining an existing one would've benefitted me more" (does it matter, 7 years after? I don't think so), because that is what he believes. Since that moment, he never felt satisfied about the answers I gave him about why I wanted to join Improbable, even though I clearly stated that what I wanted to do was helping them in succeeding by fully commiting years of my life to their company and main product, which is what I truly believe. The answer was something like "why don't you go and work for Unity then?", and my further replies were ignored.
5 days later, the people from the Talent team said that I wasn't going to get the job. I asked for
detailed feedback, because I wanted to understand what could've gone wrong after 10 interviews (5 remote, 5 onsite in the same day),
I'm really sorry about how it ended, especially because I was really going to commit to Improbable, and would still do it, and I think it's pretty sad that the whole process was sinked down by just one person, and for "personal opinions" rather than objective criterias.
