I have noticed that the example you set when you start somewhere new is what is expected of you for the rest of your time at that company. To clarify, if you start a new job and work for free an extra 40 hours a week then you will forever be expected to do that. I made the mistake of doing that to 'prove' myself and I ended up working very long hours at a place which I wasn't particularly fond of. The person sitting close to me worked exactly 8-5 from day one. Everybody knew he wouldn't be at work after 5 and they never expected it.
