Interview Question

Got asked this in a PE interview. For context - this is not for FT or SA role that can be converted into FT. It IS a co-op position where I'd be working for 6 months as a "full-time" analyst summer + fall 2022 (instead of taking classes), just cant be converted to full-time. 

"say you were an Analyst on the team. how would you find new companies for us to back?"

my actual answer - i was not prepared for this question so i went by what i did prepare. i had a tech startup i kept in mind to talk about if needed. i knew an engineer at this tech startup who's my friend from high school. so my answer was that I'd use my immediate network and see if there are opportunities there. then i went into some detail about this tech startup, what they do, why i think its interesting, and then if they fit the PE firm's criteria, I'll bring the idea to him and the other principals.

Google tells me there's this thing called proprietary deal flow, but that it' also rare.

so, wanted to get a gauge on how my answer was and what a more solid answer would look like.

update: I got the offer im so happy rn LETS FUCKING GOOOOO
