One recruiter phone screen. Two phone interviews. One to sometimes two onsite interviews, and each onsite has around 6 rounds of mixed behavioral and technical questions. The overall experience was very positive. Recruiters were very professional and stayed on top of things. There was literally no gap at all during the whole process, even though it took nearly a month to finish everything. All of the interviewers were very friendly and they were the expert in the field. The interview questions were fair, for both the technical ones and behavioral/management ones. Had the chance to chat with engineering leadership in the company, and was very impressed with the caliber of the top level team. They are thoughtful, aware and methodical. And that's probably one reason why Unity is thriving today.

Initial talk with recruiter who guides you through their process. Transparent description of the process: 3 interviews and offline technical interview. Initial interview covering 2 software technical problems and some behavioral questions. 3 hour non-interactive technical challenge run through Codility consisting of 2 relatively easy code challenges. 2 interviews, each with 2 interviewers that are at the same level or above covering some unity specific technologies, general programming questions, and behavioral question.
