One of the two biggest red flags in a logbook is sim time that has been logged as anything other than sim time. Read FAR 61.159 and see what sim time can actually be used for. It may seem irrelevant, but it is a quick way to get yourself into an unpleasant conversation in an interview. Also, every simulator or FTD has a Letter of Authorization from the FAA that tells you what that simulator is authorized to count for in your logbook. Get that LOA from your flight school now, because many schools have closed their doors and you may not be able to get the LOA if you wait.
