Fixed Income S&T versus WM Analyst in New York

Hello world,

I am a junior at a non-target school and am having trouble deciding where to intern this summer. I have an offer from a boutique Fixed Income Sales and Trading firm, and am waiting to hear back from final round interviews at Morgan Stanley and J.P. Morgan in their wealth management SA position.

The S&T firm is a startup, and there is an opportunity to gain equity in the company (if it is distributed). It is a very fast growing company with great early success, and it is not in New York. The internship this summer would be unpaid, but with full time possibilities at the end.

I feel like the S&T position is a cooler position where I could potentially learn more, and might be what I want to do in the future. However, I am unsure of what full time salaries are like at these small S&T firms, and it doesn't exactly provide the job security that I am looking for.. Also, I am unsure if not being in New York will cut me off from some opportunities in the long run. What are your thoughts? I am trying to put this in a 1 year outlook and a 5 year outlook, and make my decision from there.

Thanks!
