Nagarro Product Owner interview questions

Very bad experience with me Garu I got a call that there will be an IQ test then after two days I got another call saying that I have cleared the interview post that I have for after waiting for two weeks I got another call saying that the requirements for the position that I was being interviewed for have change and hence the second round might not even happen what was the point of wasting my time if the requirements that Nagada has our such fickle requirements not recommended very very bad interview process
