Pros
The people you work with are generally some of the best you'll encounter. Helpful, friendly, resourceful. Most departments work great with each other, which is awesome. Your boss and your coworkers are your friends. It's work-from-home, provided you're a full time employee. At least for IT/technology staff, this is a pretty good perk. Lack of commute is great. The balance of work/life is excellent. There's nothing to complain about, other than the cons listed below.
Cons
The pay is substandard for the experience someone has in the field. 2 years of experience is required for a tier 1 tech support position, however, the pay is anywhere from $12 to $14 per hour DOE. This does not pay the bills, unfortunately. This happens to be the case for most departments, from the people I've talked to. Morale can be low at times in regards to that... You'll be a generalist if you're tech support. Making marketing materials, etc. This would normally be a good thing, as you get to have your hands on all kinds of stuff, but in the case of eXp, it gives upper management the supposed authority to make you do things, such as cold calling employees and asking them why they haven't reserved a slot to the yearly conference. Thankfully, that idea was shot down promptly. No provided benefits. There are discounts, but it's pricey, and at $14 an hour, 1/3 of your pay goes to your benefits. This is understandable, as it's a small company.
