OYO Senior/Mid Level (Technology) interview questions

The process was standard 2 rounds. However, the interviewers were not very clear with the questions / expectations. Was asked question(s) like why not use x database vs y. That too when you communicated that you've worked all your (work) years in x database. Additionally, it seemed the interviewers had no idea whatsoever for role they were interviewing a candidate. Was through with 2 rounds in about 1 hour or less. Kept waiting for next 1 hour and 15 minutes and finally was informed that I should leave for the day. No clarity / communication about the status. The commotion on the entire floor was a big let down in itself and everything seemed so random. Total waste of time.
