Questions are very high level and most of them are of level of AWS solution architect certification exam which I don't think needed for this role.One of the devops Interviewer was quite rude and was difficult to understand his questions so candidate can try give expected answer. My interview was good not sure why not got selected for 2nd round but it seems they have very high expectations from candidate.You should check if candidate really has knowledge and worked on tools which he has mentioned in his resume and related to your JD. Don't judge candidate based on any unrelated random questions he may have never worked on.
