Most interviews go well because most candidates are genuinely well-suited to the role. But it’s worth knowing what a concerning answer actually looks like, so you can trust your judgement when something feels off.

Vagueness about checks

A hesitant or evasive answer about their DBS certificate, First Aid training, or right to work in the UK is worth pausing on. These aren’t awkward questions — any experienced nanny expects them and should answer confidently.

Can’t describe a typical day

If someone struggles to walk you through what a normal day with children actually looks like — activities, meals, routines — it may suggest limited hands-on experience, regardless of what’s on paper.

Dismissive about safety

Watch for anyone who treats First Aid, allergies, or emergency procedures as a formality rather than something they take seriously. This is one area where confidence should never replace preparedness.

Speaks negatively about every previous family

One difficult placement can happen to anyone. A pattern of blaming every previous employer is a different signal — professionalism includes discretion.

Reluctant to do a trial

A confident, experienced nanny generally welcomes a short paid trial, because it works in their favour too. Strong resistance to any trial at all is worth exploring further.

None of these signs are proof of anything on their own — but a pattern of two or three is worth taking seriously.

Trust the checks, and your instincts

Formal verification — DBS, references, First Aid — rules out most risk on paper. Your own read of the conversation covers the rest. Both matter.
