I work for an investment bank and have interviewed at plenty of other financial institutions, including other investment banks and hedge funds. Few have commented on my open source work, and those that have basically said, "We checked out your project, it looks pretty cool." I had one particularly tech-savvy CEO personally reach out and try to recruit me because of my open source work. My project wasn't directly related, but he recognized the similarities between the problem domains, and that impressed me. But his wasn't a financial firm. I can't imagine any tech-centric organization being hostile toward open source contributors, whether they're an investment bank or not. I could maybe see it on teams that aren't tech-focused and are led by old-school business types who just don't "get it". But teams where tech is their biggest asset, like electronic trading? No way. If you run into this sort of thing when applying for jobs in the financial sector, you're looking at the wrong jobs (or the wrong banks). Look for roles on electronic trading teams or HFT. The work is more challenging, and the compensation is better anyway. Better still, apply at Susquehanna or Two Sigma, or some other place that really recognizes the value of their engineers. Stay away from huge banks like Citi.
