Otsimo interview questions

I did a take home code challenge and then an interview with a difficult algorithm question that was completely unrelated to the internship profession. Then I have received an auto generated rejection email.

There was no interview and they asked me to complete a difficult case for this internship. Although they did not make this case mandatory, which was quite difficult for an internship, it was mandatory because since there was no interview, this was the only subject they could evaluate us on. Even though I made the case, I did not get any feedback.
