Pros
It looks good on your resume. If you are in a customer facing role, you will learn absolutely top notch demo and presentation techniques.
Kontras
Way too many managers across the company trying to prove they can "add value" by mandating you take training and certification tests on areas that have nothing to do with your job. Even if you have a written bonus plan, don't expect the company to honor it. If they think you've made enough money, they'll hold some back. Very German culture - there is a process for everything and if you think you'll be able to get something done quickly, you're wrong. The environment is extremely controlled in terms of time recording and expense processes. Very, very high pressure, high stress environment with a continuos focus on "flawless execution". Should you fail to execute flawlessly, expect to spend a lot of time with your manager discussing your deficiencies. Complete management focus on appearances, not results. Arrogance towards customers, and an attitude that it's completely ok to mislead a prospect about details as long as you "tell a good story".
