Payment is some of the lowest in Germany. Associates receive around 33k Euro before tax. They like to highlight that work is heavily commissions based, although the commission structure has been severely curtailed recently. In the past, some (those working on key accounts) were able to make a good supplement income through commissions, which has now been cut with a maximum ceiling so that management can get away cheaper.
Team structures are advantageous to some (those who are lucky to work on attractive key accounts) and a pain to others (those who work on small or international client projects that do not yield nearly as much).
No raise or promotion is given freely in recognition of hard or dedicated work. You either ask for it or remain disappointed. Chances are, you would still be disappointed, even if you ask for it.
This job has little to teach or offer to "boost your career" - in fact, it gives you next to nothing in transferrable skills that other employers might be holding out for. They highlight that the ad-hoc project work is "exciting", but it is always the same scheme of progression, no matter the topic.
The aforementioned amenities are a way to rope employees in to working overtime (some continue to stay in the office late, until midnight depending on workload). Apart from unpaid/unrecognised overtime, Guidepoint is very inflexible with work time - anytime you have an appointment for anything you will need to ask for permission to come in late or leave early.
