CASTLE GLOBAL interview questions

This company shows no respect toward candidates whatsoever. they don't reimburse for hotel for onsite interviews, but I went anyway because I was a new grad desperate for a job. Phone interview: LC merge intervals First round: LC Find peak element. The interviewer seemed unengaged and gave no hints whatsoever. Solve the problem anyways. Second round: Something has to do with grouping labels... Not your typical algo question. Purposed union-find but the interviewer didn't seem to know what this is... In the end asked me to code on a laptop. Third round: The HR came in and claimed their CTO is "away" so my interview was over. As expected got my rejection letter a few days later... Definitely the worst interview experience I have ever had.
