Pluspunten
Interview process is similar to most silicon valley/tech companies, with all common stages where they evaluate your technical skills and behavioral aptitude. The process is well documented inside Unity Careers site and the good thing is that they stick to it. Very well organized at every stage with clear communication of what to expect at each interview round, so no surprises. HR partners are there to assist you all the way in case of doubts with very prompt answers. Interviewers are not improvised and know how to extract the needed information from you without making the interview process more stressful than necessary. This makes a much, much smoother experience than other tech companies. We all know how stressful the interviewing process can be, not need to make it more stressful than what it should be with improvised, inexperienced interviewers or surprise tests.
Minpunten
No cons, I believe that this is how it should be.
