When answering with three words your previous employer would use to describe you, avoid any terms that can be construed as a negative quality. You might be a person who jokes around or uses humor on the job, but if you describe yourself as comical, the interviewer may view that as unprofessional.

"I have a letter of recommendation from my previous employer, and they described me as honest and dependable with excellent interpersonal skills. They said they trust me with any of their clients and crew, and if I say I will do something, I follow through. In my five years with the company, I called in sick three times due to having pneumonia, which was backed up with a doctor's note. They described my interpersonal skills as excellent and said I could communicate effectively with a diverse group of people."
