Editor's note: In today's human resource market, are you up against some fierce competition? Saying the right thing can mean winning or losing your dream job.

Last Tuesday, we talked about how to answer tough questions such as "Why do you want to do this job?" and "Why should I hire you?". Here we give you some more examples on how to answer those nerve-wracking interview questions.

Why are you leaving your current role?

Whatever you say, be positive. This is not the opportunity to complain how unfair last year's bonus was or how unreasonable your current boss is. Whatever your reason, make sure you turn your answer into something positive.

If you're feeling undervalued in your role or have had a personality clash with your boss or colleague, think of how this may sound to a potential employer and make sure to phrase your answer to present you in a positive light. Make sure you have a structured answer to this question before you attend the interview.

Simply state that you like a new challenge or change of environment. Be prepared for counter questions. For example, if your answer was "I'm looking for a new challenge", get ready to answer questions such as "Why are you looking for a new challenge?", "What would you describe as a new challenge at this stage in your career?" or "Why did you not approach your current employers about being given such a challenge?"

Always focus on why the new role is perfect for you and less on why your current role is not.

Tell me about yourself?

Remember that this is not an opportunity to tell the interviewer your life story.

When interviewers ask this question, they are interested in your work. Such as what you enjoy in your career and as a person how well you will fit in with the culture of the company. What they really want to know is what interests you, how skilled you are and what strengths you are prepared to bring to the organization.

Cater the answer to the role you are applying for.

A good answer to this could be: "I'm a very dedicated worker; I enjoy being part of a team and working in a challenging and dynamic environment and I also work well independently. I like meeting new people and particularly enjoy being involved with administration for projects and events."

Where do you want to be in five years?

This question is a favorite among interviewers. You may or may not know where you want to be in five years but it is always good to have a set of goals that you would like to achieve in the years ahead.
