HRT emailed me asking for an hour long screening interview. The interview was fairly disorganized and the woman interviewing me did not seem to have much experience with interviews. She often asked me to repeat my answers to the questions (she was clearly writing down a summary of my answers for her boss). Her tone of voice and explanations of my questions came across as slightly unprofessional.

The first round screening was an automated coding assignment on code signal. Had to solve 4 questions in 70 minutes. Classic leetcode style questions with roughly medium to hard difficulty
