HELP! I have a BIG interview comming up! What to ask?

research the company.....so you can small talk the interviewer about the company...ask how many ppl work for the company..]if you say something negative..back it up with something positive...if they ask what are your weaknesses...tell them what it is..but then say.."im working on that but doing........................never let you sentence end with a negative point..be confident..try not to be nervous..don't Smoke or drink coffee before going in..don't chew gum..be quick quick answers....and if you are really nervous and draw a blank you mess....just be honest and tell them..."wow..this is really nerve wracking...."and laugh it off....you will do just fine and GOOD LUCK
