If you're running short on time to prepare for an interview, one question you should definitely be ready to answer is what you're most proud of accomplishing. This is a tough one because there are a lot of ways in which you can answer it. The worst thing you can do is to answer the interviewer with a blank stare.
First, brainstorm as many things you're proud of as possible. Unless you're in sales or a metric-oriented field, you are probably going to come up with vague statements. Below are questions to ask yourself about each accomplishment you've listed. This will help you refine them, and in turn, determine which is your best example and the one to use in an interview. You can only answer this question with one achievement. The interviewer has asked what you are most proud of, so you must pick only one example.
