Vertigo Games BV interview questions

I was asked to complete a code assignment. The task description was pretty clear, except that the form of delivery was not stated. The challenge implied lots of abstractions in the system to be made, so for the team's convenience I decided to use three different forms of delivery that could be evaluated (out-of-the-box Unity project, Unity package with scene samples, and just the code). All of them contained the same code base and documentation files which I carefully attached in order to give a clear understanding of the API and the system overall, implementation examples etc. Soon I've got a feedback of that the solution was good but not enough to proceed. I've requested technical details on what did they like in my solution and what they didn't. Got the following back: "the code is duped 3 times" and "0 comments in the entire code-base". Was expecting everything but not such a frustrating way to filter the candidates.

The interview consists of 2 phases, first of all, that is a 30 min call just to get to know the company better and you as an applicant. Your reason for joining the company matters. Second interview is with an HR manager, which is asking about your experience and what are you looking for to gain/learn during your internship.
