Most hiring advice about “red flags” is junk. It was written in 2012, recycled in 2018, and has not met a modern career. Let us fix that.
Some red flags genuinely matter. Others are lazy pattern matching that screens out great candidates. Knowing the difference is the whole game.
Red flags that actually matter
Vague achievements are the big one. If every bullet says “drove growth,” “optimised processes,” or “led strategic initiatives,” with no number, no product, and no customer, that is a problem. Good operators remember their numbers.
Job hopping with no explanation is another. Three roles in three years is fine in 2026. Three roles in three years with zero narrative thread, vague reasons, and no progression is worth probing. Ask. You might be surprised.
Regression in seniority without context deserves a question. Someone moving from VP back to IC can be healthy, or it can signal they were managed out. You will not know until you ask, but flag it.
Inconsistent dates are the quiet one. CV says 2021 to 2023, LinkedIn says 2020 to 2022. Usually harmless. Occasionally it is a cover for something. Always check.
Flags to stop treating as red flags
Short stints during 2020 to 2022 are not red flags. Entire industries collapsed. Startups folded. Layoffs came in waves.
Non-linear careers are not red flags. A designer who did two years in product, then marketing, then back to design is often more valuable than a linear lifer. They bring context the rest of the team lacks.
Career gaps for parental leave, caring responsibilities, illness, or burnout recovery are not red flags. They are life. Penalising them costs you strong candidates and, in many jurisdictions, exposes you legally.
Short tenures at known bad employers are not red flags either. Sometimes the mature move was to leave fast.
Be nuanced, or be wrong
The point of spotting red flags is not to eliminate candidates quickly. It is to know what to ask in the interview. Every real flag becomes a question, not a rejection.
