Air Space Intelligence Backend Engineer interview questions

Terrible interview process. I was scheduled for 3 interviews, one with the C-suite and then a coding and a systems design. I did the first round and it went well, I went into detail about my project experience and described the algorithm and they seemed impressed. However, after the round was done I just got an email saying that they are canceling the behavioral and coding rounds, with no explanation as to why. Terrible hiring process
