Also, KNOW WHAT YOU HAVE ON  YOUR RESUME and be prepared to thoroughly go through it without looking at it for atleast 30 mins.

The questions you posted above- they might not be that complicated ( you have limited time). Know the basic concept rather than focusing on individual questions. It will help a lot.

Again, GOOD LUCK! It's not that hard ..you can do it OR atleast TRY YOUR DAMN BEST
