Madison Black interview questions

I was interviewed by 3 middles aged white men, poorly dressed claiming that their company is diverse. I got the approval to move forward with my application to the final stage on the Friday afternoon and asked to prepare during the weekend a presentation about "myself" and present it on the last interview which will be held on the following Monday at 9.30 am which I did. Despite that all the information in the presentation was already mentioned in the early stage of the process, the lining of questions was irrelevant, questioned my honesty and felt like an interrogation.
