Telling a prospective employer why you want to leave your company can be a quite common situation most of the interviewees have to go through. The way you answer the question shows your attitude as well as respect you have towards your current employer and the organization you work with. 
 
Best Answers to Impress Your Interviewer

- When I went through the job responsibilities that were mention in your advertisement, I saw a better career path and an opportunity to build a new skill set. 
 
- I was recruited by my current employer for a certain job role, but now they want me to work in another department and handle a post that would not help me climb up the career ladder. 
 
- As of today, I have more than five years of experience in this field. So, when I re-evaluate my career goals,

What Not To Say?
 
1. Do not criticize your current employer 
 
When you answer this question, you need to avoid criticizing your current employer even if your current boss is the worst boss you have ever worked with. You need to make sure that there is no sarcasm, anger or any resentment in your tone when you talk about your current organization. Besides, your choice of words does matter a great deal. So, you need to sound grateful towards your current organization when you explain to your interviewer why you are looking for a new job opportunity.
 
2. Do not speak about the workplace arguments
If you have gotten into a fight with a co-worker and that is one of the main reasons why you are looking for another job, it is best to avoid mentioning it even when the other party is guilty. Because once you reveal this, the interviewer might think of you as a quarrelsome person with no professionalism. On the other hand, the interview might think about what guarantee he has got that you will not do the same if they select you for the post

3. Do not show over-enthusiasm over salary
 
If the job you are trying to get pays you more than your current salary, and you are desperate for some extra money, you should not be open about it at the interview. Because this can give your prospective employer the impression that all you care about is money. 
 
4. Do not talk about why you need a job change unless the interviewer asks you
 
Do not talk about why you want to leave your current company unless the interviewer asks you. There is no need to be pressured and explain why you are looking for an opportunity to quit your current job unless you are asked. Instead, you can talk about some of your professional achievements as part of your self-introduction. 
 
So, the best way to tackle this tricky question is to be prepared to give a few good reasons that help you win your interviewer.
