I thought John helped to provide some good points during his talk. Yet, the interactions I have had with Career Services have proven to be much more fruitful. For example, telling us to get on LinkedIn and Glassdoor should not be new to the group in Week 1 of winter term.
However, I found that he talked down to the group a lot - referring to the group in the room as "kids", and mentioning that we can use experience from high school. Many of us in the class room had professional lives before attending the MBA program and I find it difficult when that part of our experience is glossed over.
In the future it would be helpful to prepare the speaker by telling him who the audience will be. It may also be helpful to designate certain speaker events as great for MBA students or MSF/MACC students since we are all at different points in our careers.
