I encounter a problem.

Before the interview, I have to fill in the job application form. In the job application form, there is a question: "Can we contact your present employer?"

So, I should answer yes or no?

Yes to show that I am confidence and nothing to hide. Also, if I unable to get the offer and the interviewer calls to my present employer, this leaves a bad impression to my present employer and a very awkward situation. My present company might think that since I want to resign, why should them paid training fee for me in the future?
Also, what if my present employer says something bad about me when the interviewer calls them?

No and the interviewer might think I have something to hide.

So, yes or no?

Wann ask...

When applying or interviewing for a job, why the employer asks:
1. Have I worked as a government official previously?
2. Have I worked for employer auditor before?
3. Did I work as a contract staff with them before?
4. Did I work as a direct or an indirect contractor with them before?
5. Did I work for them before?

What is the purpose?

Oh, I see.
