I would say the experience as a developer/analyst in any hedge fund or bank depends on 1. How well is it doing (PnL) ? Affects your job prospects and compensation/bonus. 2. How much alpha do you contribute to ? (back office vs mid office vs front office). You make more closer you are to the market, projects are much more exciting and you learn real world finance from the frontlines 3. People and Culture. 4. Compensation: Wall street pays base + bonus where latter takes more and more importance with time. Normally they can grow way faster than any silicon valley firm. But in these times, hard to say unless you work at a place that is still doing quite well.
I love where I am right now because I love learning and I am practically overwhelmed with how much I can learn and grow in my current position + people around me are fantastic (insanely smart brains + nice people). My projects have ranged from script automaton to price modeling, and there is much more to come as I learn. That keeps me excited.
