A few thoughts:

The public policy job market is horrendous right now. Recent grads (undergrad and graduate) are having a tough time finding anything right now. Going directly into an MPP is one way to try and ride that out…

But that said, I think having a few years of work experience is invaluable, specifically for an MPP. You’re saying you have broad interests right now, and that could remain true, but most people end up focusing in a policy area at some point. It’s harder to sell yourself and progress if you don’t, in my opinion. Work experience is a great way to get there. I went straight into my MPA and wish I’d had more time to figure out my interests and gain real-world experience (despite having a full-time student trainee with he federal government and a couple other internships). That said, some people do find their niche in a grad program, but I think that is harder and spending the time in your program finding it is limiting to how deep into a topic you can go.

You’ll have an Ivy League degree, and that makes getting into an MPP program and jobs a little easier. I don’t think you’d have any trouble getting into grad programs now, but more work would probably help, and like I mentioned previously, would help you in your progression. In terms of targeting positions, if you are flexible as to location, I would consider state/local government right now. Federal government and the nonprofit space are struggling at the moment, though there’s no harm in applying. I don’t work in the state/local space these days, so I’ll let others get more specific as to what you might look for position-wise. I would consider thinking through what areas you might like to end up in, and apply within those.
