Not too hard. No leetcode. More about testing my conversation skills and my past experience/projects. Had 4 rounds with one take-home test. Between the 2nd and 3rd round. Take home test was using unity to build a VERY simple project. There was an interview on this test asking me to describe my solution and make some live coded changes.

First interview was a virtual interview with a recruiter. She was very friendly and was very straightforward about the position, what the hiring manager was expecting, etc. She was blunt in that I was likely not going to qualify as I was in software for too long and didn't have much experience with networking, hardware, etc. and let me know pretty quickly. Although I wish the decision with the HM was made prior to an interview, the interview itself was pleasant so can't complain other than that.

Mess of an interview, they ran late, had to re schedule the meeting and they were late again and at the end they said that specific position was not available, but wanted me for another similar one
