13. What are your weaknesses?
Do NOT mention key weaknesses here. This is not the place to say you are bad at meeting deadlines or you never mastered high school mathematics etc. Turn this question around to your benefit. For example, you are 'overambitious' or 'extremely attentive to detail' or 'like to take on too many projects'. Make it sound positive.
14. What are your career goals?
Show you have thought forward and are committed to your career.
Any of these are good examples of attributes employers are looking for: intelligent, hardworking, quick to learn, enthusiastic, honest, efficient, productive, ambitious, successful, and compassionate (in the medical fields)
16. How would your colleagues describe you?
Do not bring up anything negative here.
