Comparing two internship offers — Private Banking Credit vs Microsoft Finance Intern

Hey everyone, torn between two fall internship offers and looking for outside perspective. I want to preface this by saying I find both appealing which is making this harder than I expected.

Option 1 — Private Banking Credit at a Big 6 Canadian bank (out of province, 4 months)

• Supporting credit structuring for high net worth clients
• Financial statement analysis and credit proposals
• Would require reneging on the microsoft offer I already signed

Option 2 — Financial Analysis at microsoft (home city, 8 months)

• FP&A supporting AI business Solutions
• Forecasting, variance analysis, ad hoc reports
• Already accepted and signed
• Stronger brand recognition generally

My situation
I have a few internships under my belt in financial services but nothing that's actually been inside a banking credit role yet. Long term goal has loosely been corporate banking but tech finance is starting to appeal to me too. The banking role would be my first real credit experience. The tech role is interesting and I've already signed but the work is more FP&A than banking.

I find both exciting for different reasons. Banking appeals because it's what I've been working toward and credit judgment feels more durable and less replaceable long term. Tech appeals because it's where the world is heading, the lifestyle is better, and the Microsoft brand opens doors everywhere not just in financial services.

Main concerns:

• If I do tech now will I realistically land a banking role next recruiting cycle?
• Is reneging on a signed offer at the student level career ending or manageable?
• Can I pivot to tech later if I do banking first?
• For people who've been at both which did you find more fulfilling day to day?

What would you do if you liked both?
