Hi!I'm currently an Eng Manager in a FAANG (total current comp is high end 6 figures). I've been approached to join a startup as a co-founder on an area that's really close to my passion.Money is not an issue (there is funding and even it there wasn't, I have enough buffer to hold for at least a year and not change anything on our life style).What I'm looking for is advice from people that did the jump from Big Tech to startup and then went back to Big Tech: what went wrong? what are the things you would've done different? What did you regret not doing?I'm obviously thinking, if I do the jump, do it and not burning bridges, by helping find a replacement as much as possible and leave the teams I support setup for success.I'm thinking that if for some reason the startup goes to hell (there's always a risk there) I could still go back to Big Tech because tbh I do enjoy it here, but I'm also really interested and actually miss a bit the startup scene.
