Relativity Software Developer Intern interview questions

I have gone through 2 interview stages: phone screening and a short live coding. The first round is very chill, behavioral questions and 2 questions in English. Immediately was invited to the next stage. Then, there was a coding interview, a few tasks involving class implementation and basic searching. They hinted I will be taking the next steps, but then ghosted completely, and I got an automatic sad email after a month. I do acknowledge I did not do well during the interview, but at this stage, I think they could at least remember about informing me about the decision earlier than a month later. An automatic email during the interview process past resume screening is also very out of line for me. During those 2 rounds, the interviewers vere nice and sounded helpful (with round 2 being a bit messy, but might have also been my fault).
