Respondology Backend Software Engineer interview questions

They sent me an automated 2-hour HackerRank assessment without any prior communication. I decided to just spend the time anyways and completed it with a perfect score. Respondology reached out the next day and scheduled an interview with me. The day before the interview was scheduled to occur, Respondology deleted my interview invite without explanation and ignored my emails seeking clarification. Don’t waste your time here. Clearly they don’t care about treating anyone with respect.
