Well where I work, we did in fact throw a number of resumes out the window specifically because of hotmail and AOL email addresses.
But then again, I work in IT, those people SHOULD know better.
But what if they are just using those AOL or hotmail addresses as their personal spam box? Maybe they are old email addresses that they give out to unknown people/companies?
I sure wouldn't be giving someone I don't know my personal email.
It's the same in every field of activity (banks, everything), not only in IT.
I admit it might be hard to realize at first but you should get use to it eventually !
Looking at the replys to this question, everyone seems to be saying some variation of this. But, it really isn't. I have a regular retail job, and let me tell you there is no 'personal internet browsing' there. If you stop to breath for 5 seconds, someone will be there to ask you why you aren't doing X, Y, or Z. So no, I will go against the groupthink here and say that people don't get 'burnt out' from working 8 hrs a day. Trust me, people handle it just fine.
On the other hand, i'm currently at my office job, browsing slashdot. Oh the irony.
Make sure your code does nothing gracefully.
