What your interviewer is really trying to do with this question—beyond identifying any major red flags—is to gauge your self-awareness and honesty. So, “I can't meet a deadline to save my life” is not an option—but neither is “Nothing! I'm perfect!” Strike a balance by thinking of something that you struggle with but that you’re working to improve. For example, maybe you’ve never been strong at public speaking, but you've recently volunteered to run meetings to help you be more comfortable when addressing a crowd.
If you’re unsure of where to start, review how to match your qualifications to a job. Don’t forget to think beyond the job description and consider which of your skills and accomplishments make you a better candidate than the competition. For example, maybe you have an additional certification that makes you more knowledgeable about the company’s product than the typical salesperson. When you’re honing your pitch, remember to be positive and to reiterate your interest in the company and the position.
Tip: It’s easy to get hung up on figuring out your single most impressive accomplishment. Instead, think of a few achievements that showcase your work ethic and values. If you can, pick examples that also tie back to the job you’re applying for. The STAR method is a great tool to ensure you highlight not only your role but how you drove business results.
