Pros
This is a great first job out of college for someone who doesn't quite know what they want to specify in career-wise. Apex offers great real-world experience, trains its employees to be comfortable on the phone and in front of clients, and give them sales exposure that they can use in any future job. The people are fun and young (my boss was barely over 30) and Apex touts its "work hard, play hard" mentality.
Kontras
The base salary is very low and it takes a good 6-12 months to build up your commission. As a recruiter, the job is very repeptitve and mundane. Employee and contractor turnover is relatively high and there is not much loyalty between Apex and it's contractors (both ways). These jobs aren't mentally stimulating and even though I was the youngest person in my office, I felt as if I was the most intelligent person there. I left because I did not feel challenged, was bored by the position, and I didn't like the type of contractors I had to deal with on a daily basis.
