Took 4 rounds of interview. The first round was with direct manager. The second round was with 2 team members. The third round was with other teams that would work together. The last one was with HR

tl;dr absolute waste of time, pto, and effort for a clearly unorganized hiring process where no one spoke to one another 1st interview - Phone call with a VISA employee who shared the title I was applying for. Was more of a technical interview than a general call about experience, what I am looking for, etc. Wasn't terribly hard, but I got asked basic coding questions. I was told I was being considered for 3 jobs in this call. I informed them I was qualified for 2 of the 3 and would not like to be considered for the 3rd job. 2nd "interview" - Hackerrank test. The test did not directly pertain to the job I applied to. The title of the test was a dead giveaway that this was not a QA focused test but more of a Dev focused test. Anyway I had dev experience and completed the test, but it would have been difficult without that experience. No idea how I did, but got another interview. 3rd Interview - Onsite interview. This interview consisted of me speaking with 4 different employees over 4 hours. Every single interview here was white board questions. They all had different roles at Visa and were basically questioning me and seeing which role I'd fit best in. 1 of the interviews was for that role I previously stated I did not want nor was qualified for. Bombed that interview terribly because I had never done that work before. Other 3 were alright. Lots and lots of technical questions with a 5 minute break in between. Not easy even when you know the answers to their questions. Two days later, I got an email saying "Congratulations! Your final interview went extremely well, and we want to schedule a call between you and your future manager. Please respond with a time asap because we want to get an offer out asap!" I obviously was pretty happy that all my hardwork was rewarded. I emailed back giving a time, and I was told this was the time to ask HR related questions, and day to day questions. Manager doesn't call me at the scheduled time, but calls me 2 hours later while I was driving home. Manager tells me I was selected for the role I told them numerous times I did not want nor did I have experience. I was very confused but said sure might as well ask my Visa questions. Manager interrupts me and starts grilling me with technical questions while I am driving home. Was not expecting that at all. Numerous white board questions via phone about a subject I don't know. Manager ends the call after 2 questions. I never got to ask Visa questions. 7 days later I get a generic rejection saying I don't have enough experience for the role. WELL NO DUH. I told that to numerous interviewers, and I said I did not want the job. I email the recruiter and he tells me they were only hiring for that role that I said I did not want. I question that saying why was I told there were 2 other roles, and why was I interviewed for those? Tells me there are no other roles, so I got on Visa's career page and see those other roles there. Email him back and he ghosts me. I am livid with this interview process. I went from preparing my 2 week notice statement, to being rejected for a job I didn't apply to and now ghosted.
