Jane Street Product or Blackrock Applied AI for Summer 2026

Jane Street Pros - way more (over double) the pay - chiller culture, probably better hours

Blackrock Pros - would be doing actually technical work - the group id be joining publishes pretty often, members exit to top AI labs

Thoughts? How important is that distinction between better early career pay and work life versus (presumably) better eventual career success and continuing to build your quantitative skills? For context I did QR at different bank this summer
