The assessment day consists of several hour long exams, an aptitude test and three short interviews. For the tests revise gcse level mathematics and basic set theory and you will be fine. The interviews are 'strength based' so they will focus on your personality rather than competencies. you can't thoroughly prepare for this but as examples are always helpful i would suggest thinking of some specific experiences you may want to talk about which you think demonstrate the qualities they are looking for.
Interview questions [1]
Question 1
What the thing you have done which you are most proud of?
I applied online. The process took 2 weeks. I interviewed at FDM Group (Frankfurt am Main) in Jun 2017
Interview
1. Telefoninterview
2. Ganztägiges AC
Im Telefoninterview wurden Fragen zum Lebenslauf gestellt und wie bereits weiter unten beschrieben kurz ins Englische gewechselt.
Das AC besteht aus einem 1stündigen Interview, bei dem es hauptsächlich um die Lernbereitschaft und Selbstreflexion geht; DESIGMA Test und Case Study (Flow-Chart).
Das AC war gut organisiert, das Geschäftsmodell wird etwas beschönigt.
I applied through college or university. I interviewed at FDM Group (New York, NY) in Jun 2017
Interview
Had a screening phone call where they ask if you're willing to relocate and to schedule a phone interview. Phone interview was fairly simple and quick, they asked very basic questions about Java, C++, and SQL. During assessment day, you have to take 3 exams. Two of the exams are just to assess your math and logic abilities. They give you material to prep for the third exam.
