My experience was in the Hamburg as a Marketing Expert (Telefonberatung, Outband-Anrufe). This company is based on a culture of lies and deception, since the very day you are recruited - if they really want you, they will tell you lies only to have you sign the contract. Nothing is stable: responsibilities, working hours, bonus scheme, etc. Too many power games and internal politics. Their slogan is "we offer a stable workplace" - this is totally false. In the 6 months I worked there 2 projects were closed, and the employees were either sacked or re-positioned in inferior projects (mostly inbound telephony). When our project was canceled, they begged us to stay (including those who still hadn't taken their vacations) and work as hard as we could, which we did, promising us bonuses and retribution for having given up our vacations. The only thing we received a month later was a letter threatening us not to open our mouth. Terrible company, which does not comply with the minimal standards of decency, and probably neither with some of the local laws.
