Red flags before you even reach the interview

A vague or contradictory job description, a listing that has been reposted repeatedly over several months, or a recruiter who cannot clearly explain why the role is open (a new position versus a replacement for someone who left) are all early signs worth noting. Persistent high staff turnover in a specific role is one of the strongest predictors of a difficult working environment, and it is entirely reasonable to ask directly why the position is vacant and how long the previous person was in the role.

Red flags in how the interviewer behaves

An interviewer who is dismissive of your questions, repeatedly checks their phone, or arrives significantly late without apology is showing you, in a low-stakes moment, how they are likely to treat you day to day if you accept the role. Watch also for an interviewer who speaks negatively about former employees or the previous person in the role, since this often signals a culture that blames individuals rather than examining process or leadership.

Red flags in what is said about the role and culture

Be cautious of phrases like "we work hard and play hard" used to justify long, unpaid overtime as a cultural expectation rather than an occasional exception, or a reluctance to give a clear answer about typical working hours, on-call expectations, or how overtime is compensated. Vague answers about career progression, training budget, or how performance is actually reviewed, when asked directly, often indicate these things do not genuinely exist in a structured way, regardless of what the job advert implied.

What to do if you spot a red flag

One red flag alone is not necessarily disqualifying: interviewers have bad days, and a single vague answer can simply be poor communication rather than a hidden problem. A pattern of two or more red flags across the process, however, is worth taking seriously. Ask direct follow-up questions rather than dropping the topic, request to speak with a potential future colleague rather than only the hiring manager if the company allows it, and trust a strong negative instinct even if you cannot fully articulate the specific cause.

Frequently asked questions

Is it acceptable to ask about staff turnover in an interview?
Yes, phrased professionally, such as asking how long the previous person was in the role or what the average tenure looks like on the team. A confident, well-run organisation will answer this directly; noticeable discomfort or deflection in response is itself useful information.
Should one red flag stop me accepting an offer?
Not necessarily on its own, but it is worth raising directly before accepting rather than ignoring it and hoping it was a one-off. If you raise a concern and get a thoughtful, specific answer, that is often reassuring; if you get another vague or dismissive response, treat that as a second data point rather than a coincidence.
