Pros
Good pay, benefits; co-workers were friendly; opportunities to fit niche needs if you're fast enough on the ball; flexible with scheduling.
Cons
Boring, tedious days; only a step up from telemarketing because the product has already been sold and now you're just responsible for getting participants on board; QA was ridiculously subjective; quotas made working with clients feel impersonal and rushed (had to talk to X number of people per shift and not supposed to talk with anybody for longer than about 10 minutes at the most); overtime MANDATORY (generally not less than an additional 5 hours/week) for the majority of the 15 months I worked there due to not having enough coaching staff to cover the growth of the company (turnover rate is phenomenally high, with an average of half of every new hire cohort - about 20-30 people - gone by the 6-month mark); extremely limited opportunity for advancement; many people who advanced to specialty positions weren't qualified for their new jobs, but were advanced because they were "interested"; rapidly changing demands on coaches (workload, QA); most definitely a poor fit for anyone with a public health background, as the knowledge I used was basic nutrition/weight management/exercise/stress management type information rather than program planning/implementation, and therefore did nothing to build my skills or advance my career.
