Interested in funds on the west coast in LA or SF. What are the work hours?

[hedgefunder]

I am either going to apply as a SWE for a fund in LA or SF. I already have work experience as an intern developer at a fund. I either want to get a FT developer job, or go back for an MFE degree and get a quant developer job. Would love to know about the smaller funds as well as the well-known ones.

What are the work hours of a fund in LA or SF? Is it 5am to 3pm like a lot of people say?

I was wondering also the hours of a developer vs a quant?
