Wow, that's well above the norm. What job is it?

That is a good starting salary. Make sure you stick to your guns when you move about. If you are staying in your area of expertise you should never take a pay cut. Ever.

I've heard that their hours were rather long. Is that true? I myself am considering getting a job in finance in London, so I'd like to know what I can expect.

Graduation from a BSc? I didn't realise Bloomberg made offers this high to graduates. I thought the square mile standard was still the 25-30 range.
