Honestly, don't go too hard on the "power day" preparation. I was so focused on complicated concepts, while they asked me basic questions.

On the job description, there were tech skills that you were supposed to have, which I did. However, I was surprised that during the interview, they told me I was being interviewed for a Site Reliability Engineer position, which, in my opinion, is totally different from a Platform Engineer.

Most of the time, I was talking about myself and describing my past experience. All the questions I received, especially during the "fit" interviews, were related to SRE. At one point, the interviewer asked me if I knew what SRE was. I knew the position, but that was not what I was supposed to be interviewed for.

My piece of advice: Don't trust their facial expressions. They will laugh and make you believe that everything is going well, making you believe you are giving the right answers to the questions. However, don't expect anything until you hear back about the final decision.

Behavioral: Tell me about a time you had a disagreement with your manager.

Case Interview: Discuss different types of software testing and perform a math calculation to determine if a team's budget is sufficient to meet their testing expectations.

Two Fit Interviews: Primarily discussing your past experience. What are Recovery Point Objective (RPO) and Recovery Time Objective (RTO)?
