The company seems to be pretty cavalier with candidates' time. The first step of the process (before ever talking to anyone) is to complete a case study that takes 8-10 hours minimum to do something of quality. The case study is actually a fun an interesting challenge, but it appears the company uses these case studies as their starting point of candidate assessment. If they don't like your case study, you get an automated rejection. So they never engage with you in any way, but expect a significant investment of your time. Effectively, if you are applying to this company, you should consider this first case study part of the application, not the interview process and then ask yourself if you are willing to invest 10 hours into an application to a company. To the company, a lot of your blog posts talk about wanting feedback and even after the rejection you ask for feedback and say how important it is to you, and yet I'm seeing pretty consistent feedback that you don't seem to be interested in addressing. Again, I think the case study is excellent, but if you are asking for such a significant investment from your candidates, you owe them a small fraction of that commitment in return.

Initial contact was having to do a difficult test and it was completely open it did not feel very personal at all. You essentially go on their site and read the problem and it felt irrelevant to the role
