Academic probation for one semester senior year, will job offer be rescinded?

Why not

It seems that this will most likely depend on your university's policies for admission to the undergraduate business program. I suggest that you look up their criteria for admission, and speak to your dean about what information is and is not available to the business program admissions committee, and also about his personal experience in these matters.

Might impact your chances of getting into the b-school, but for the actual job, if you have a 3.7 at that point you will be more than fine. They generally just look at the number, at least for finance interviews; if a transcript is requested, it's usually only to verify your GPA is honest. Good luck!

For IBD, it won't matter. For B-school it might (doubtful). I just received,and accepted, an offer to attend GSB. I have 3 big fat Fs on my transcript from my undergrad days. I was not only on academic probation my first year, I was also subject to disqualification. I finished UG with a 3.5, and 3.9 in MS program. Point is, I doubt it will matter for either IBD or Bschool.

Would firms look down on delayed graduation in terms of internship applications? i.e. if I applied to an SA job for the summer after my 5th year as an undergrad will it raise eyebrows?

Obviously that is provided I do get into the b-school
