From my experiences in interviews and interviewing candidates, at this level you need to be able to answer a good majority of technical questions about RHEL. If you are familiar with any flavor of Linux, including Debian, you can rest assured other than config files, the filesystems and binaries are very similar. I would go over the RHCSA exam objectives and focus on the ones you are least familiar with.
