Real easy. If you got the interview and you don't lie, you could possibly get the job. Tell them straight up that you don't know but are willing to learn and then tell them what you've learned so far. That is the hard part. Go out and attempt to learn some UNIX by doing a tutorial (like
Usail ).
You've only got a week, not enough time for someone to explain the differences between Windows and Solaris (or UNIX for that matter).
