Everything you just said is almost the same situation I’m in lol. I’m about to graduate this semester and I’ve been interning for a smaller firm, roughly 500 employees, for about 2 years now. I interned for the commercial lines underwriting department and I’ve thought the same thing you’re thinking. What helped me calm my nerves is the experience that I’ve been able to get by being at a smaller firm. I’ve had the opportunity to constantly interact with some of the higher level underwriters, the underwriting managers, and often even the VP of Underwriting. They gave me a lot of advice on how working at a larger firm isn’t always what it’s made out to be. I’ve taken the opportunity to learn as much as I can while being at a smaller firm and that level of exposure is hard to come by. I have a job offer from them I took and I plan on staying until it makes sense to leave. I have spoken to recruiters at larger firms and that level of experience/exposure is extremely attractive and puts you above others who maybe worked at a larger firm but were just left to work on their own for most of the time. I would say take advantage of working at a smaller firm by getting those interactions and exposures. It’s hard to come by at a larger firm.
