Pros
CDW is not all sales. A large part of the company is focused on backend support - sales operations, shipping/receiving, marketing, product, hr, etc. I can't speak to Sales roles. But on the corporate side, there is much to enjoy about working for CDW. Work/Life Balance - Never had an issue if it was needed that I leave early due to emergency. I generally work about 40-45 hours per week. I come in between 7:30 and 9 and then leave 9 hours later (with an hour-ish lunch). Salary - Salary is competitive with industry. I will say that it seems outside hires will generally be compensated greater for a role than an internal transfer/promotion would receive. Benefits - Benefits won't blow you away, but nothing where you feel the need to purchase supplemental insurance or anything like that. Perks - Perks are all right. Company outing once a year, team outings a couple times a year, vendor lunches, etc. These are nice, but they're as I've described - perks. You don't select a job over a perk.
Cons
The biggest drawback for me is the lack of training/career growth assistance. I believe in making my own way, but at the same time it would be nice to have some direction with regard to trainings/classes/etc. I'll never understand why a company would not be interested in improving it's own employees' skill sets.
