Dropping out of grad school with F's: how will this affect job prospects?
Did you try seeing if you could formally withdraw, rather than do so "de facto"? A withdrawal means that you normally don't receive grades for courses (although some schools note a withdrawal while having a failing grade in a course).

The likelihood that a future employer will overlook this depends largely on who's doing the applicant screening. If your "direct boss" is handling the process, you have a chance of convincing them that the grades aren't reflective of your true abilities. On the other hand, if a human resources "specialist" is handling the screening process, a grade of F will unfortunately mean your application will probably end up in the "circular file."
