I'm interviewing as an experienced hire for Bain, entering at the consultant level. I'm required to give a presentation, and the objective is to give insight into my experience by showcasing a project I've done. The focus is on: the challenge, approach, recommendations, and results.

The interviews will also be observing my communication and presentation style. Post-presentation questions may be about difficult team situations, management of multiple stakeholders, my analysis, and how I came to my recommendations.

I haven't heard about this aspect of the interview process very much, so I'm wondering if anyone has any kind of insight or advice about it. What are the interviewers looking for? What are some common mistakes to avoid? If I have 45 mins for the presentation and Q&A, how long should the presentation be? How casual (humorous) can I be? I would appreciate any tips!

I will be presenting on a game-like program I oversaw, in which I worked with my company to implement many interventions that resulted in us doing well in the program, avoiding a multi-million dollar loss, and potentially winning a multi-million dollar reward.
