Unity interview questions

There is a hr phone interview and it takes around 15 min asking my background. A week later get an interview with a team manger, we talked about 30 minutes around my background and team's work and spent another 15 mins on an algorithm problem. Got a second round interview in the next week, solved two medium algorithm problem and a follow up question.

Email, phone call, coding test, 5 - 1 hr interviews all online Very confusing and frustrating. Started out well and did not get the first job. The issue was that I did not get the job because of a lack of a certain skill. They knew this before I interviewed. So why interview? Then I was set up on another interview as they liked me as a candidate. Call went well, but I think we both knew it was not a good fit. Then I was supposed to interview again and although I appreciated them trying to find a place for me, it was frustrating because I didn't get job descriptions nor context and really did not understand what was going on. I pulled myself out before the third interview. I could not manufacture skills and it all seemed a waste of time. Although everyone said that they did not need certain skills, that's the reason I was given. Recruiter was nice, but tough to work with. I wrote them my concerns and left the process after a month in the system.
