I guess the interviewer customizes all his questions based on the project you choose. Talk about a big project you were a part of. Why were you chosen to lead it? What were the steps you chose to implement it and why? Talk about the other teams you worked with. Talk about implementation details. How long did it take, how many people did you lead, and what were the challenges/ How did you define milestones and distribute work? How do you delegate work and make people successful vs. managing the overall timeline? What challenges did you have? What did you learn? What compromises did you have to make with the product manager's vision? What issues did you have with other teams? How did you maintain high quality, especially during the rollout? (Testing, Monitoring, alerting, rollout strategy) Hiring manager feedback - D.C. said I communicated very clearly, but that I have no sense of accountability or humility and that I spoke poorly of coworkers and treated them like "low performers" (his words, not mine). He also apparently spoke against me in the onsite debrief and didn't want me to join even at the G8 (~Software Engineer II) level. That is crazy. I have never had an issue in behavioral/eng. experience interviews before. The interviewer was D.C. He completely made up this detail about "low performers," and I don't understand why.
