1. Misleading pay structure- They claim that they pay *per hour, but they actually pay based on what they perceive as an hour worth of work. For example, the work may even take you 4-5 hours, but they will only pay for one hour because that's what they claim is the average time their "Experts/experienced employees" take to finish. Also, any time used in prep is unpaid. The structure is clear though. But if you expect to earn money for all 20 hours/week in your part-time engagement, that's almost impossible unless you work full time towards this job.
2. Part-timers are not earning anything during training, and after training when their billable hours start, they have to pay back with work for training. So, effectively, you aren't earning anything for the first one to one and a half months, while working a lot.
3. Be very cautious before signing the contract, it's quite shady and doesn't have much for employee protection. They can abruptly fire you without any notice/warning and you will be stuck with a non-competition agreement for many years, i.e you can't do similar work. So if admissions consulting is your main job, reconsider joining.
4. Their hiring process is pretty much trial and error, they have a very simple interview process and most probably they will hire you if you're good at their functional test. And after joining, if they do not find your performance good enough after minimal training, they will simply fire you as soon as one-two months after joining. That's how they maintain a pool of good consultants.
