Pocket interview questions

I applied and an interview was set up pretty quickly. they wanted very quick turnover of interviews and tasks but when it came down to waiting to hear from the recruiter on the last stage, nothing. I even contacted them and they've completely ignored me which is especially annoying after you've prepared and done a task for someone. I now see why they have 0% employee growth and barely any female employees as reviewed on TP/GD. Really unprofessional. it's quite annoying because the interview was quite hard, and I felt like I did a really good job - you could tell I put a lot of effort into my research and my task, and then nothing.
