Native Instruments Developer interview questions

It starts with a half an hour discussion with an engineering manager about the candidate's past experience and current expectations. It is also an opportunity to find out about the role and the company. If all goes well this is followed by an offline coding challenge (i.e. to be made home and sent to them when finished).

The process consisted of an initial interview followed by a simple technical test and then three additional interviews each with a different focus (Technical, teamwork, and business). The technical test was a classic and straightforward linked list test in C++. They encourage the use of any C++ library if required. You can complete the test with no time limit and without anyone watching. Overall the interviews were casual and well structured. All team members that I spoke to (8+) seemed nice and most questions were easy to understand. The reason my experience being rated negative is due to the rather ironic feedback that I received. In the final interview, it was stressed that I'd hear back within two days with either an offer or a rejection with detailed feedback. I never heard back from them directly but instead needed to call the recruiter after not hearing back for over a week. The received feedback only said that they felt my answers were "too vague". After four hours in interviews and over three hours completing a technical test, I find this feedback not only useless but insulting.
