How to sell yourself in an interview
3. Demonstrate by example
If you make a statement about your abilities, such as "I'm a good problem-solver" or "I can handle high-pressure situations," be prepared to have an example ready to support the claim. Nothing is quite as embarrassing as not being able to come up with an occasion in which you demonstrated a quality you say you possess. Remember, it's the example that makes your claim credible. Without it, you're just boasting.
