10 Red Flags to Watch for in a Shanghai Nanny Interview

A red flag in this context is a candidate response — verbal, non-verbal, or about-the-paperwork — that statistically correlates with a placement ending early in the Shanghai expat-family market. Some are about competence. Most are about fit, honesty, and how the candidate handles being assessed.

We sort red flags into three tiers:

• Yellow — slow down, ask a follow-up, weigh against the rest.
• Orange — pause the interview, raise with the agency, weigh much more heavily.
• Red — thank her politely, move on.

Most of the ten items below are yellow or orange. Three are red.

1. (Yellow) Vague employment dates. 'I worked there for a few years' is not the same as 'I worked there from March 2022 to August 2024.' Ask for the specific months.

2. (Yellow) Cannot name the children she cared for. If the candidate can't name her last family's children's ages and first names, the reference will be hard to verify.

3. (Orange) Refuses to do the CPR demonstration. See our CPR-certified nanny guide. Refusal is data.

4. (Yellow) Salary expectation is 30% above her stated experience band. Either she has a credential she hasn't surfaced or she's testing the family's price awareness. Ask why.

5. (Orange) Will not provide prior-family references. Every reasonable Shanghai nanny has at least one prior family willing to take a call. Zero references after 3+ years of work is unusual.

6. (Red) Discloses a prior placement ended because 'the family was difficult' with no specifics. Two professional adults can have a placement end for many reasons. The candidate who can name one is honest. The candidate who blames generically is rehearsing.

7. (Yellow) Discomfort with the trial-day proposal. Most candidates expect it; resistance suggests prior trial days went badly.

8. (Orange) Discomfort with the contract being bilingual. A candidate who insists on Mandarin-only or English-only is signaling something. Ask why.

9. (Red) Cannot or will not name the agency she's currently registered with. Direct-hire is legal; ambiguity about her current professional status is not.

10. (Red) Specific factual contradictions across her resume, the agency brief, and her own answers. Memory differences are normal; structural contradictions about years, employers, or duties are not.

Two patterns:

1. Discounting non-verbal cues because the verbal answers were polite. Shanghai interviews tend to be more formal than London or NY equivalents. A candidate who is polite and warm verbally but visibly tense when asked about her last employer is telling you something the words aren't.
2. Asking only the family side what was wrong with the last placement. Ask the same question of the candidate, then ask the agency, then ask the prior family. The three accounts should triangulate. If they diverge structurally, that's the signal.

Families also tend to over-weight the impression from the first 15 minutes. A candidate who is warm and confident at minute 5 is easy to like. The harder, more useful read is at minutes 45–60 — when the candidate has been asked specific questions for half an hour and is showing fatigue or impatience or both.

Sequence:

• Print or save the ten-signal checklist as a one-pager next to your interview kit.
• During the interview, mark each signal yellow / orange / red / not present. Don't try to remember.
• After the interview, review with one other adult — usually the partner or a friend — within four hours.
• For any orange or red signal, ask the agency directly and in writing within 24 hours. Their response time matters; their content matters more.
• For a placement that has two or more orange signals across CPR, references, and contract language, that is enough to either ask for a second interview or move on. One orange in isolation is rarely fatal.

Two meta-patterns worth pushing back on with the agency, not the candidate:

• Agency dismisses your concern as cultural misunderstanding. Sometimes it is. Often it isn't. Ask the agency to specify what they mean and which prior placement supports the dismissal.
• Agency pressures you to decide same-day. Reputable Shanghai agencies expect a 48-hour decision window. Same-day pressure is almost always about their candidate pipeline, not yours.
