Native Instruments Mechanical Engineering interview questions

After applying i got an invitation for a telephone interview with the human resource and mechanical engineering department. The interview took around 45-60min. Two weeks later Native Instruments called me for a verbal agreement. For a first check i got the employment contract via email. A few days before my job started i was invited to sign the contract and clarify organizational things. In addition to that i had a meeting with my chief to talk about the exact content and termination of my work.
