How to Have a Positive Trending Slope Line in Regards to Career Progression

Hi everyone,

I am currently in the summer of my freshman year going to my sophomore year in the fall. Currently, I am a FA for a top tier bank in Canada (RBC, TD, BMO) within their capital markets division. I was fortunate to secure this position through the luck of some great connections, but besides the title, I do not find the work quite satisfying. As recruitment for 2020 has already begun, I am just wondering how to maximize my potential in regards to internships.

I have talked to some alumni as well as coworkers who have suggested that I:
1) Return back to the bank in my next year (I seem to have done a satisfactory job, and the managers seem to like me)

2) Go join a boutique IB within Toronto (Osprey, Firepower, Origin Merchants - only negative side is they don't offer salary), from Linkedin, seems like the main case for the majority of the alumni from my school

3) Apply for associate at big 4 (tax, audit, assurance, hopefully to leverage into their consulting division)

My primary goals are to break BB IBD in third year (although school is not necessarily a target, still sends plenty of students to BB), or at the very least, big 5 IBD. My secondary goals are to break consulting at tier 2 firms like Deloitte, Oliver Wyman, AT Kearney during my junior year.

The main concerns I have are in regards to:
1) I do not find the work interesting. I know interns are there to do the "slave work" while the people higher up on the hierarchy are there to make money. However, the finance work I do mainly involves account regulations and classification of instruments and derivatives. Nothing particularly interesting, so hoping not to return there if possible.

2) Not really sure to do networking at the boutiques, many of the websites don't offer career sections, nor do I know the timelines, and in addition, besides the three I mentioned, I am not sure about any reputable boutiques that could add value to my repertoire. The main concern here is whether going from a big 5 FA to small boutique (most likely unknown to BB), will add any value in my profile, or even, look detrimental (as it might imply I could not secure a returning offer, etc).

3) Accounting has never really piqued my interest, so to do an internship solely for the sake of doing an internship seems like a waste of time and backwards thinking, despite the lateral movements it might provide.

So with that lengthy post, to recapitulate my question, in essence, what might be the best opportunity for me to experience in my sophomore summer in order to maximize my chances of reaching my primary/secondary goals.

Thank you for the people who took the time to read my post, if there are any questions anyone might have for me, feel free to send a PM or post down below. Appreciate the help.
