Rejection? I took that personally

So I did 5 interviews before I got ghosted...I personally feel they just used me for filling quota and get me stressed all time during that period...

So I went there in the company... look for the manager.. And eventually he came and met me And I asked him why not hiring me He said I fucked up the interviews... I then showed him the recordings of the interviews..and asked him where ? Did that happened? He said he will look into it . I forced them to give me an answer why I didn't get selected as I have all the proof that eventually I was the right candidates.

I then got an email saying I'm over qualified for this role later during the day
