Was made aware of job through school job posting. This was for an entry level position. After emailing the Comcast rep behind the school job posting, I was emailed a short technical questionnaire which served as a screening. I had an hour to complete 10 simple questions covering statistics, SQL querying, and general OR / industrial engineering. After submitting the questionnaire, I was invited to take part in a three rounds interviews with managers and engineers via a Microsoft Teams video call. The first interview was with a manager and mostly consisted of generic company culture-style questions and was fairly easy. The interviewer and I got along decently well. The second interview was not good. The interviewer here was the same person who emailed the questionnaire. This manager asked fairly repetitive questions and expected overly complicated answers to those questions. He also gave very little feedback in the conversation. There was very little chemistry here, so to speak, and the interviewer seemed like he was looking for very specific answers to his questions. He wasn't very open to alternate solutions. It was fairly clear that this round's interviewer had the largest say in the hiring decision for this role. The third interview was with two engineers. This final round was decent overall. The two engineers largely asked the same questions that were asked in the second round, but these interviewers were much more open-minded and were better conversationalists. After completing the interview, I knew that I would not receive a job offer. The second round did not go very well, and that manager and I did not get along. I did expect to receive a simple rejection email, especially given the chain of emails the second interviewer and I exchanged in the lead up to the interviews. But it seems he couldn't be bothered.
