Narrowing down three words to describe a person can be difficult. However, according to Syracuse University Career Services, it is best to use positive adjectives that can be backed up with specific examples.
The descriptive words used to describe a person should ideally play to the strengths of that individual. For example, if this question is asked at a job interview, the three descriptive words should showcase the positive aspects that the interviewee will bring to that specific job. The words chosen by the interviewee should have specific examples that showcase why each word was chosen. For example, if a person chooses the word "timely," he could point out how he has never been late or missed a day of work.
