Infinityn International Global Account Based Sales Developer Rockstar interview questions

We had the interview, and after that the assignment was supposed to be sent but it took 3 days which was fine, they gave me a really complex assignment to do in 3 days so imagine what they wanted and I did it, I sent it but the recruiter was on vacation for 2 weeks so I had to wait and after the 2 weeks I tried to contact her but she ignored my email, and 1 month later she just sent an email saying that I didn't meet the requirements which again, never said at the beginning... It is frustrating because I invested a lot of time and energy in that assignment and they acted like they didn't care my work.
