Unity Senior Backend Engineer interview questions

I didn’t apply for any position at Unity, a recruiter contacted me saying my profile was a good match for the positon. The position looked interesting so I proceeded and schedules a Telephonic interview. 1, The interviewer was 1 hour late from the scheduled time. 2, No Questions were asked related to technical tools/programming, it was all generic and etc. Next day, I got a message saying I do not have enough years of industry experience. My years of experience was already mentioned in my CV, not sure why the recruiter contacted me in the first place. Waste of time and not recommended.
