DNEG R&D Programmer interview questions

Reached out to the recruiter directly and heard back from them 4 weeks later. They first set up a basic screen. I must have passed the screen because they told me they'd send through a technical test shortly. However I would not recieve it for another 3 weeks. I took the technical test within the week, but ( due to various schedualing conflicts on their side ) I didn't get an interview with my potential supervisor for another week. I thought that went well and was not asked any technical questions, but they would turn me down a week and a half later because I somehow "lacked technical depth". I taught PhD students at Stanford. So, yes, you can easily figure out who this is. So I conclude they just didn't like that I didn't tell them what they wanted in my interview.
