Don’t proactively point out flaws.
You should always have answers ready for gaps in experience or skills that may appear on your resume. If you’ve planned ahead for these questions, you may be tempted to preemptively explain shortcomings to ease the interviewer’s mind. However, you should avoid bringing up any areas of weakness unless you’re specifically asked about them. Maybe a specific skill isn’t critical for the department, or the hiring manager doesn’t question why you would only spend a year at your first job. By bringing up potential red flags, you risk making minor issues seem bigger than they actually are, and you could be making an interviewer more worried about the gaps instead of putting them behind you.
