Interview
Worst.
Reis HR consultants invited me to TIAA office at 8.30. it was 20 kms away from where I live.
I reached at 8.15 and then they made us wait till 10.30 to give any update. At 10.30 they told me that interviews are being lined up and I might be called for interview any time. I got called for round 1 which was kind of screening round yet so much technical at 11.15 approx. Lasted for 15 mins. After half hr they told me I have cleared it and HR asked to have lunch before round 2.
Since it was a Saturday I was okay with round 2 being conducted after lunch. Post lunch , they made me wait for another 1 hr to have a interview online! Which was ridiculous. The main purpose of visiting office was to have interviews in person!!
That round 2 went exceptionally good for me and from experience of round 1 , I knew I am good fit for role they were looking for.
Interviewer was also impressed and told me frankly that they were having stack process and I was in top 3. I had got 2 tricky questions wrong.
2 days after REIS HR calls me and says I am not going ahead saying my interview was not so good.
2 weeks after another HR calls me and asks for round 2 scheduling. In the office. Again.I asked for my previous candidature and she got all awestruck and told me she would get back. Still hasn't.
Lesson learnt : Always opt for online interview.

Interview
Despite clearing the final round, there's been no proper feedback from HR. Repeated follow-ups are ignored, and it feels like fake interviews are being conducted without genuine intent to hire.
