Well your potential employer must think you are capable, so clearly they see it in you. Take the position and just work hard to improve what you see as weaknesses.
The hiring strategy for many of these firms is to hire everyone who shows up and wait to see who pans out. The jobs are commission based, so a) it's really cheap to employ a worker, and b) people who don't pan out will quit on their own pretty quick because they won't be making any money.
A lot of firms will show up at college career fairs and basically offer a job to everyone who submits a resume. If 20 people accept the job offers, two or three might make it past 6 months in the job. This hiring strategy is NOT about hiring only the best. It is about bringing in so many people that the few good ones will rise to the top while the majority fail.
Point is, I wouldn't necessarily take the job offer as a vote of confidence.
All that being said, "investment broker" can mean a lot of different things. There are high level finance guys working for respected institutions who are investment brokers. There are investment brokers who are basically glorified telemarketers. I'm assuming that this job is the latter, given the context and the OP's comments.
