I have a few interviews this week coz i m job hungry...i need a better job... god damn it

those job pay are pretty decent...around 40-45K, not bad, comparing to my job now..sigh...
those jobs are mainly partial sys admin AD, partial helpdesk..300 end users....troubleshooting..break/fix...not big deal...
those companies have few servers, 1 company has dell mainly...which is what i m doing at work now....no problem...
I hope they wont' pick on me for the things that i don know pretty well..such as SHAREPOINT SERVER...crap....are there any chances i will get picked on?????
i hope to get a jump in this summer.....i been stuck too long....
wish me luck...
