GE Aerospace interview questions

In the Phone interview with HR, they just asked generic questions such as "tell me about your past experience", "why do you think your experience is relevant to what we are looking here" etc. In the hiring manager interview, they gave me a sheet of paper with a simplified bearing model on it and asked what type of stress components would I expect to see under different loading conditions and why.

When was a time you had to step up and lead your team? How did you get everyone on board?
