FIS UI Developer interview questions

There was telephonic round where we had a discussion about the role and responsibility, then technical round where all the technical question asked. And then final round was the manager round where again the role and responsibility and some personal question asked.

I applied through a referral in May 2020. The interview process took hardly a month. I received a call saying that my telephonic interview has been scheduled at 4.00 but till 4.15 i dint receive any call. Later, I received a call saying i will join for interview along with my associate. Then i received call at 4.30 and then interview lasted for 45 minutes. I received a mail after 2 weeks saying i have been cleared round 1 and asked to fill candidate information sheet. Then i got a call for managerial discussion after a week and zoom interview has been scheduled for the next day afternoon 2.30 but till 3 none connected. So i called the same person who scheduled this interview. I got to know that interview is not available so he will reschedule it for the next day. Next day just two formality question was asked. Again i dint get any update unless i called after a week. Then only i came to know that i have been rejected. They are just wasting our time.
