The interviewer is good. He asked some programming questions and gave an in-depth overview of what projects team recently work on. However, I passed the first round but I decide not to move forward. Because the HR (M...) in Unity is unexpectedly unprofessional. She didn't explain questions well, or didn't even want to reply in a more understandable sentences. And she also missed the call scheduling time without any apology. With a HR being so irresponsible, I will have concern about company's hiring quality, as well as any legal issues that needs HR to get involved
