Pros
If you're right out of college it's a half way decent starting point; just one notch above an unpaid internship. Make sure you fluff up your resume since other companies in the area also view Tech Data as a entry level company. Other perks you can get from working in sales or marketing are some free products, event tickets and shirts. It is a paycheck albeit on the low end of a salary range for comparable positions at other companies.
Cons
There are many downsides to the company: low pay, unqualified management who have no sense of the industry or business in general for that matter. The only way Tech Data knows how to make money is to bilk their vendors out of marketing dollars by overcharging for activities, but then not following through with them. They embelish reports to make business look better than it is. I've been working in corporate America for over 20 years and this is the first company that I ever heard the phrase "throw you under the bus", and the only place I've ever experienced it. I think they pretty much coined the phrase. Mangement is so lacking in skills the only way they can make themselves seem taller is by cutting off the heads of their subordinates. They don't lead by example and many times there are feuds between director and director, manager and manager, etc. It sets the tone for the entire company. They are their own problem and it's keeping them from growing business.
