Here are the most basic interview questions you will be asked during an interview:

Tell me about yourself...
Why did you leave your last position or why are you looking to leave your current position?
Why should we want to hire you?
Why would you like to work for us?
What is your biggest weakness?
Tell me about a time you worked with a challenging boss or co-worker and how you handled it...
What is your greatest achievement?
Do you prefer to work as part of a team or independently? (this is a trick question-the answer is always BOTH!)
What is your bottom line salary requirement?
Do you have any questions for us?
