A：Hello Chen Hao. How are you?
A：What is it?
A：I've worked on a couple of projects with her. Why?
A：Why is that a problem?
A：That bothers you?
A：What did you say when she came to you?
A：I have a couple of suggestions for you.
A：Let's sit down over there.
A：Sue must have some positive traits or she wouldn't be working here.
A：I suggest that you make a list of her strengths.
A：Try not to focus on her shortcomings, but list them out, too. You can call them areas where she needs to grow.
A：You begin by saying that she is a good team player, but could benefit from the opportunity to work independently and grow professionally. That makes you honest.
A：Let the interviewer know that you have worked with Sue on a limited basis so you can only speak about your experience on the team.
A：That's cowardly. Besides it will reflect poorly on you.
A：You have another choice. You can tell Sue that you aren't comfortable in giving references to her because you are afraid of saying the wrong thing.
A：It is difficult when a colleague who is not a good worker asks you for a reference.
A：If you agree to be a reference, rehearse what you plan to say. Don't allow yourself to be drawn into areas where you are not comfortable.
