Optiv Sr cloud engineer interview questions

Went through 3 rounds of interviews, They seemed really impressed with my knowledge, hence the promotion through rounds. On the last phase where in interviewed with team members for a senior role, one interviewer kept asking "trick" certification questions. How those transcend to a job role seems puzzling. All the role related function questions I was asked, I answered as confirmed by the other team member. I did get a generic rejection letter after 3 rounds of interviews.
