OLX Group Performance Engineer interview questions

They started interviewing me for one position. Then I talked with the CTO and he told me I was better suited for a "much better position"; however, when I talked to HR again they told me that it was just because the original position had been filled. They made me work with a different recruiter because the position had changed... They wasted another 3 hours of my time doing the same interviews again, with different people. Then when they brought me onsite, they asked a bunch of questions that had NOTHING to do with the position and was in fact just a way for the engineers to wave their genitals in the air to show how cool they were for knowing the most pointless things that don't make them good engineers. A few of the interviewers were even very rude during the process. Completely ignoring me, answering personal phone calls, and even getting up and leaving the interview to do non-work related stuff
