Prepare To Talk About Specific Accomplishments

To set yourself apart, make sure you prepare specific facts and speak about details. Ensure you have facts and numbers to show what you accomplished in your previous jobs.
However, it is worth noting that interviewers are less interested in what you did in your previous role than in how you did it.

Therefore, dont spend too much time speaking about your accomplishments. Instead, spend more time talking about how you solved problems and overcame various handles to achieve success!
