☛ Take time to think before you answer the question.

☛ If given a pen and paper, take notes and write down key information. Use the paper to make calculations, write down ideas and structure your answer.

☛ Ask additional questions if you feel you are missing information. The interviewer is often expecting you to ask to find missing information.

☛ Use lateral thinking and be creative. There isn't always just one right answer. Just make sure your answer is backed up by sound logic and numbers that make sense.

☛ Make sure you know your math. At minimum you'll need to perform some basic arithmetic or mathematical calculations.
