The most difficult questions in any interview for a nursing job are those designed to throw you for a loop.  When an interviewer asks you what your worst trait is, and you’re not prepared, things can be disastrous.  So, you need to have a game plan for these questions as well.

You have two options: 

1) Pick a positive that could have negative impacts, and emphasize the positives.  If you’re hard-charging and sometimes miss details, you can focus on your single-minded determination.  Or, if you are very blunt, you can show how your honesty benefited one of your previous employers.
