2 phone interviews with HackerRank. Data structures and algorithms questions. First interviewer was great, but the second was horrible. My second interviewer showed up 15 minutes late, but grew up in the same place I live, so we connected on that. Throughout the interview, there were technical difficulties on his side, and he was forcing me to use built-in class methods that seemed unnecessary. He was also making jokes and cursing. By the end of it, he just wanted to end it so he could go and get lunch, so he told me I did pretty good, and he was passing me. I was told they would contact me soon, and I got an email 4 days later rejecting me.
