Correct Group interview questions

I was contacted by a staffing agency. I first spoke with the agency and they introduced the role. After submitting my resume, I got a call a day later from the Meraki recruiter to set up an introductory call. That call lasted 20 minutes and he went over my career history, salary, and goals. The recruiter sent over a list of technical topics to prepare for during the next round. My first real discussion was with an engineer. They asked about routing, wireless, security and mobile questions. It sounded like the engineer was reading off a set list of questions. I passed and the recruiter set up a video webex with the hiring manager. With the manager, we went over career history again, education, and some technical topics. A day later I got an email saying I wasn't selected. I would have appreciated some feedback because I thought I did pretty well on all interviews. I'm not sure where I could have improved. Overall, average interview experience.

They will ask you to do an exam with some technical questions multiple choice (windows server, mac and office 365. They don't expect you to answer everything, especially the questions about mac if they not looking for a Mac engineer.
