Tapad Senior Software Engineer interview questions

Started nice but ended unprofessionally I had a call with a recruiter about the company, the position and the process. We also talked about my career and my interests. I was informed there would be a live programming interview on video conference. The live coding part was fairly standard, I solved it and then we had a small conversation about the interviewers' role and the projects. I was told that next would be a take home assignment. It was again a fairly standard assignment building a rest api for high scale. I was told only the main coding part matters. I did a fully working micro-service tested with high throughput along with multiple persistence for both scale and durability. There was supposed to be a review of the assignment with an engineer from Tapad. However, I didn't hear from them for about 2 weeks and after which I got a canned response about how there were other candidates they chose to proceed with. It is a bit frustrating that I wasted my time on a take home assignment and they didn't even bother having a short call to discuss it, even if they found another candidate (probably cheaper) for their need.

Mostly easy standandar interview. Except in the second session of the in site interview, the HR comes to me and says they are not moving forward because they don't do functional programming and my solution was "too hardcore functional".
