The reality of day-to-day work is a far cry from what is sold to you in the application process.
In many projects you are supporting the digital transformation of companies not as an agent of innovation but as an outsourced human resource. The real innovation tends to comes from the client. The reason the client hires Capgemini is to push their decision through in the company (due to highly complex organisational politics) or because the client lacks executional resources.
Even though there is pressure from the market to show initiatives for work-life balance, the high fees and tight deadlines mean that you must show total flexibility to client wishes. There can be no real discussion about work-life balance under these circumstances.
Graduates get no "individual" training. The Institute in Berlin functions as a backoffice and research support for understaffed projects (due to high client fees).
You have no say about which projects you'll be working on. You'll be staffed whatever client pays for. Don't be surprised if you'll be sold as expert on a particular topic, citing past projects that never happened. The pressure to sell new projects at all cost is very high, so the managers have no choice.
