Big 4 Accounting VS Asset Management for Business School. PLEASE HELP!

Hello everyone,

My situation:

Just graduated from a non-target UC in northern california. 3.85 Major gpa in business equivalent degree, poor cummulative gpa (3.2 started in engineering). Currently interning at large california pension fund also have one past internship in wealth mangement and one as discount broker intern. No full time job prospects.

My question is... Should i continue in Asset Management and try to get whatever job I can while pursuing the cfa, with the risk of not getting a name brand job or a good job.

Or should I go a more certain route and do a summer program in accounting that would ultimately land me a job with a big four accounting firm (program has great recruiting)

I dont want to hurt my chances for a top business school more than I already have with my poor cummlative gpa, and I am wondering which route has the better probability of getting into a good business school.

Also on a side note, do business schools look at transcipts of schools you attended after undergrad?

Thanks
