Not sure I can speak to this question since I'm not affiliated with admissions at all, but I can tell you the makeup of my cohort.
Most (I'm guessing 75%, possibly higher) have some work experience. Most have either strong math background or strong software background but there are exceptions. Lots of former engineers of all kinds, chemical, mechanical, software, etc.
