The interview process showed that the local teams have zero autonomy from the headquarters in Copenhagen, as well as zero respect for my time.
To begin with, I was contacted by a recruiter out of the blue for an application I had submitted weeks before, with no email beforehand or anything. I was told that he was delayed in contacting me because there had been multiple candidates who had reached advanced stages of the interview process, but had failed. That's important to remember.
I was told I would be sent a take home coding test that afternoon to work on over the weekend. I received it 5 days later, while I was on vacation. When I got back, I put the time and effort in to writing highly optimized code, which the recruiter stressed. After I submitted it, the recruiter contacted me to tell me that he was informed by the manager in Austin that it was the best submission he had seen for that position. All of the other candidates (who had reached advanced stages) had had to resubmit with corrections multiple times, whereas the manager thought mine was exceptionally well done. It still had to go to Copenhagen for review (Yes, Copenhagen. Not the team that was looking to make the hire, or even the location, or country), but he was sure I could be onsite within a few days.
Cut to a few days later, and the recruiter calls me back to tell me that Copenhagen had decided my code was so riddled with mistakes that I couldn't possibly have the seniority required for the position.
Which amounts to this: I applied for a senior level position. I had discussed with the recruiter that I didn't have X years of experience yet, and he said that it was perfectly fine, if they liked me they would just hire me as a non-senior developer for that position. I did, however, have a tremendous amount of experience doing the incredibly specific thing this position was for (I wish them luck finding somebody else...). So essentially, the team here liked my application, but Copenhagen looked at my resume first and decided that I didn't have enough years and that was that. Then this recruiter didn't have enough spine to confess that he had wasted an inordinate amount of my time, and made up something about mistakes in my submission.
Everything about the process wound up leaving a rancid taste in my mouth, to the extant that I don't mind burning bridges here at all. So, thanks, recruiter dude, but I don't think I'll be wasting any more of my time connecting with you on LinkedIn, I can't say I'm interested in any other opportunities Unity has to offer. If you value autonomy in your workplace and your time in general, I'd stay away.
