I applied through a recruiter. The process took 5+ weeks. I interviewed at Unity Technologies (London) in June 2019. The process in general was slower than expected, however, I was kept informed throughout and my personal recruiter was excellent in prepping me, suggesting appropriate reading and videos to watch before interviewing, which was very useful. I met with my 2 unity mangers, including the hiring manager in London, and did a 15-minute presentation to start followed by a 45 minute question and answer session. They insured a relaxed but professional environment which allowed me to be ease and therefore felt I performed well. They were both very engaging and made the overall process rather enjoyable.
