One of the least understood aspects of job interviewing is this — most interviewers will not trust your opinion of yourself, they will only trust the conclusions they form about you on their own. Your job is to help them form the right conclusions by how you answer their questions.
Your best strategy is to stick to the facts and share recent concrete examples. Your opinions of yourself only get in the way of them trusting you. When you say, "I'm a hard working self-starter," they will not believe a word of it. But when you to share a brief vivid example of a time when you had to take initiative, they will believe you are a hard working self-starter without you saying it.
One of the best ways to organize your answers to interview questions is the STAR method — Situation, Task, Action, Result. Let’s put this into practice with a few common interview questions you can expect.
