Pros
The pay is on the low side, but descent, benefits are great. The people you work with are very supportive. Lot's of opportunity for a "go getter" in B2B. They like to hire and promote from within. Tons of promotions to make spiffs and extra bonus. You will get lot's of headhunters and HR people from other companies calling you with offers for more money. Once at T-Mobile you never want to leave. Most that leave come back after a year or two. B2B, It's just such a great place to work. If you are a slacker, you will be ousted and quickly promoted to customer. If you do the activities, get in front of the prospects, the sales are easy and fun.
Kontras
Training if sub-par in B2B, and it is a truly sink or swim, think fast and move fast position , as it should be, B2B product range is very limited on plans and pricing. Serious lack of direction and planning with slap shot approach to business product development. Sales Order process for B2B is still in the hard paper 13 page document stage from the 80's. Lack of coordination between Sales Reps and order filling coordinators seriously delays the process and crates huge man hour waste. You just spend more time writing, fixing and submitting orders than selling. However, they still make it fun to work there if, you don't get too uptight and just go with the flow and stay proactive. The major focus is still on Retail and you have to accept that as a B2B Rep. The cons are definitely not serious enough to be a deal breaker and you have to have hope that the "fix" is just around the corner to help you become that "super Sales Machine".
