Advisor Development Program salaries in United Kingdom

Someone I know did a fellowship and then became a mentor in the program. I was curious and checked it out; realized it’s a paid fellowship (student pay) and people also have to pay to be a mentor 🧐 Feel s like some weird cross if degree mill X pyramid scheme for mid career pivot seekers. What an I missing? Is this common?

Does anyone know the normal interview process for Impact Advisors?

Do you see candidates positioning themselves better over the years as advisors / consultants who spent time in multiple companies or as long standing full time employees of the same company?

Currently in the process of studying for the CFP Exam which I plan to take in July. I'm currently at a crossroads in career where idk whether or not to pursue a role at an RIA or a B/D. I've been given a lot of advice, but I'm trying to find out the best way to build a book and feel like there is no better place than starting out as a bank advisor. For those out there who have built a career as an advisor, whether it was at an RIA or B/D, what was your experience like?
