Dilemma: Should I wait for my dream offer or stick with the one I’ve already secured?

Hey everyone,

I’m in a tough (but fortunate) spot and could use some perspective.

Last year, I interned at a top-tier global bank (let’s call it Bank A) and recently had a positive in-person conversation with the team’s Head. They said I’m basically “in” for a full-time offer as a Junior Analyst on Trade Finance team and they just need to finalize internal headcount approvals. Problem is, that was weeks ago. Still no written offer. Timelines are vague. HR just reached out again for a quick check-in call, but there’s still no firm commitment or paper in hand.

In the meantime, I just received a formal offer from another international bank (Bank B) for their Management Associate (MA) program in Wealth Management. The pay is decent, and the rotation structure gives good visibility, although the division isn't my long-term passion since I’m more into corporate banking and solution sales.

So now I’m staring at this decision:

• Accept Bank B's MA offer: start my career with structure, training, and leadership exposure.
• Wait for Bank A's dream offer: the role is exactly what I want long-term (sales + corporate focus), but nothing is official and no timeline is guaranteed.

I don’t want to hold out forever, but I also don’t want to burn bridges or walk away from the job that fits me best. At the same time, I'm anxious about delaying my start date while everyone else moves ahead.

Would love your take.

• Have you been in a similar position?
• Is it okay to accept one offer now and back out later if a better one comes through?
• How long would you realistically wait on a “verbal” offer?

Thanks in advance.
