• 5+ years experience working with Windows, Mac and Linux systems, including systems administration for all three
I do know how to use Windows but I am much happier, and far more productive, when most of my general work can be done on Mac OS X. I can do "system administration" on Windows (or Linux) machines but prefer to make notes, handle email & calendar, and use web applications on a Mac desktop system.
I also knew that at least one project was heavily into Macs.
The third interviewer and I spent much of our time discussing the application his team works with, that I would therefore be working with.
So, I thought I was making a simple administrative request when I asked the recruiter to pass on the information that I wanted to sure that the desktop system I was provided with would be a Macintosh.
