To get a full time offer one must progress throughout the internship. This means being interested in learning the ins and outs of Fisher Investments and incorporating that into their sale on the phone. Going out of the interns way asking for more opportunities to listen to tenured Account Executives to hear how they interact with prospects on the phones and taking new tips back to their own business. Then asking their managers for advice on what they could work on to improve on the phone. Finally practicing the sale out loud to actually hear what the intern wants to say on the phone rather than just thinking about it helps smooth out conversation when actually talking to prospects.
To turn your internship into a full time offer continue to ask management and senior leaders questions. They love it when you ask questions because that shows that you have interest in the subject matter. Whether the questions relate general sales skills or markets doesn't matter. Just ask. Let them talk. Ask more questions. Also if you're serious about starting a career in sales in wealth management talk to management about creating a career path. Fisher loves to create internal career path's. Show them that you're willing to move into other roles beyond an AE. This will show that you're interested in touching different aspects of the business.
