I'm 27 years old and I haven't prioritized my career as much as I could have. For example I've joined teams that allow me to work remotely from countries of interest instead of searching for ones that had the best environment for growth as a software developer. I'm not unhappy at all with the choices I've made so far, but my goals in life are changing and it's making me wonder what it takes to be accepted into companies like Jane Street. Skill wise I think I'd have to start as a junior developer, which I don't mind, but perhaps having 4-5 years of working experience would disqualify me for those entry level roles?
