> Why is this considered a red flag? Hiring people takes a lot of work. You have to recruit and interview a large number of people, interview them until you've settled on the best candidate for the job, get them to accept an offer, and then send polite rejection letters to everyone else. If the candidate you hire then quits within a few months, you have to start the process all over again. Even worse, you've also lost several months of progress that you were hoping to make on this project with the new hire, as well as another month while you try to re-fill the position. On top of that, you already rejected your 2nd and 3rd choice candidates, who probably have taken other jobs already or are otherwise not interested. Beyond that, a pattern of short jobs with large gaps in between can be a warning sign of behavioral or personal issues that make the person difficult to work with. This shouldn't be assumed from a few short jobs on a resume, but if someone has 9 different back-to-back jobs of less than 12 months each, the interview process should do a very deep investigation into why those jobs didn't last very long so you can decide if your company will stand a better chance at retaining this employee than the last jobs.
