How much preparation does one need to break in?

You won’t really know how to be competent at the job until you’re in a seat.

Best piece of advice I’d give you is pick a few sector that interest you. Reach out to analyst (head honcho) and send them a pitch within that industry.

Also take the SIE

Thank you. 

I have SIE and 66. 

I guess the better question is how long do you think it would take to be able to make a stock pitch and generally be competent in an interview? I know it will vary, but general range for someone who can study ~ 2 hrs a day, on top of learning CFA 2 material, but little other general investment/market knowledge. 

I broke in a few months ago from a similar position. The hardest thing about breaking in is the resume. CFA level 1 & 2 will help. It goes without saying but networking is also huge. Teams tend to be lean and associates and analysts talk across teams so a connection is huge. Having a sector focus is good, but I think a better bar is knowing what you don't want to do and what your favorite is.

Once you get an interview, the things that helped me the most was 1) a good why ER and knowledge of what the job is, 2) some modeling and writing skills - they'll teach you what you need to know but having the basics is huge, 3) a good stock pitch - make sure you can keep it around 2 minutes and can answer a couple follow ups. 

Good luck, it won't be easy but it's definitely doable!
