Common Nanny Interview Mistakes (and How to Avoid Them)

We often get calls from families who are worried about making a mistake when hiring a nanny. Sometimes they're time-short and feel the pressure to decide quickly. Sometimes they've already hired the wrong person once and are determined not to repeat the experience. And sometimes they simply don't know what to look for beyond an impressive CV.

Finding the right nanny is one of the most important decisions you'll make as a parent. When you get it right, you gain a trusted partner who becomes part of your family for years. When you get it wrong, and the nanny isn't a good fit for your family, the stress and disruption affects everyone - especially your children.

At Homebodies, we've spent years helping families navigate this process successfully. In this guide, we'll walk you through the most common mistakes families make during nanny interviews and, more importantly, how to avoid them.

Mistake 1: Rushing the decision because you're time-short

One of the biggest mistakes we see is families hiring too quickly because they're under pressure. Whatever the reason, when you're time-short, every instinct tells you to hire the first decent candidate you find.

But rushing almost always leads to problems. You skip important steps like thorough reference checks or proper paid trials, you overlook small concerns because you need someone to start immediately, or you settle for "good enough" rather than "genuinely right for your family."

And then, a few months later, you're back where you started - looking for a new nanny because the match isn't working.

How to avoid this: Start your search early. We recommend beginning 8-12 weeks before you need someone to start. This gives you time to meet several candidates, conduct proper trials, and make a thoughtful decision.

If you're already time-short, be honest with yourself about what you can realistically assess in the time available and consider whether temporary cover might give you breathing room to find the right long-term match.

Mistake 2: Focusing on qualifications instead of fit

A CV can look absolutely perfect on paper: Norland-trained, ten years of experience, glowing references from previous families, First Aid qualified, enhanced DBS check... But here's what we see time and time again: the most qualified nanny on paper isn't always the right nanny for your family.

Sometimes a nanny has extensive experience but with different age groups than your children. She might be brilliant with babies but less comfortable with toddlers, or excellent with school-age children but overwhelmed by the demands of a newborn. Sometimes her expertise doesn't match the specific milestones your child is reaching.

A nanny experienced with typically developing children might not have the skills needed for a child with additional needs or who is going through a particularly challenging developmental phase. And sometimes - often, actually - it comes down to something simpler: either the chemistry just isn't there or your parenting styles don't align.

How to avoid this: Look beyond the CV. Ask specific questions about experience with your children's ages and stages. Discuss scenarios that matter to your family - how would she handle bedtime resistance? What's her approach to discipline? How does she encourage development? Listen to whether her answers align with your values and instincts. The right nanny for your family is someone who fits your specific needs, not just someone with impressive qualifications.

We've created a comprehensive interview guide with specific questions to help you assess compatibility - from childcare philosophy to communication style and career goals.

Mistake 3: Not checking for personality fit and parenting alignment

This is perhaps the most overlooked aspect of hiring a nanny - and one of the most important. You can ask about experience and qualifications and check references. At Homebodies, we do this for you, but always encourage the family to speak to previous employers too, should they want to ask their own specific questions.

But how do you work out whether someone's personality actually suits your family? How do you know if the nanny's approach to parenting aligns with yours?

During a formal interview, candidates naturally present their best selves. They know the "right" answers to common questions. But what you really need to understand is how they'll actually be with your children day-to-day. These qualities matter just as much as - sometimes more than - qualifications and experience.

How to avoid this: This is exactly why during our extensive initial consultation, we take the time to understand your requirements and only put forward nannies who are a good match.

We also always stress the importance of paid trials. A proper trial day (or ideally several days) shows you who someone really is beyond the interview. You see how they interact with your children when they think you're not watching closely. You observe how they handle real situations - a tantrum, a scraped knee, resistance about lunch. This is how you get a genuine sense of whether the chemistry is there and your approaches genuinely align.

Mistake 4: Conducting short trials instead of full trial days

Many families do a trial, but they keep it brief - just an hour or two to "see how it goes." This isn't enough. In one or two hours, everyone is on their best behaviour. Your children are curious about the new person, the nanny is focused and attentive, and everything feels positive. Equally, we've seen short trials go horribly wrong because the children were tired after school or didn't know who the nanny was, and the timing just didn't work.

But a full trial day tells you so much more. You see what happens when your toddler gets tired before lunch, how the nanny handles transitions, whether she takes initiative, and if she tidies as she goes. A full day - or better yet, several full days - gives you real insight into how this person will actually function in your family.

How to avoid this: Insist on proper paid trials. At Homebodies, we build full trial days into every placement as standard, usually 2-3 days for live-out positions and sometimes a full week for live-in roles. Yes, it takes more time and yes, you need to pay for those days. But compared to the cost of a failed placement - both financially and emotionally - it's an invaluable investment.

Mistake 5: Relying too heavily on video interviews

Video interviews have become standard practice, particularly for initial screenings. They're practical when time is limited or when candidates live far away. But here's something important to know: great candidates aren't always comfortable on video. Some nannies are naturally warm and engaging in person but struggle with the awkwardness of talking to a screen. So many things can go wrong - the Wi-Fi lags, the connection freezes, or the flow of conversation feels stilted and unnatural.

We've seen excellent nannies who came across as reserved or uncertain on video but were completely different - warm, confident, engaging - when meeting in person. If you only interview via video, you might miss someone who would actually be perfect for your family.

How to avoid this: Whenever possible, meet candidates in person before making a final decision. Video interviews are fine for initial screenings but try to have at least one face-to-face meeting before you make your final choice. The in-person dynamic often tells you things a screen never can.

Mistake 6: Not following through with thorough reference checks

When you've found someone you really like and you're eager to get childcare sorted, reference checks can feel like a formality you want to rush through. But thorough reference checking is essential.

Speaking directly with previous employers gives you insight into how a nanny actually performed in a real family setting. You learn about her reliability, her communication style, how she handled challenges, why she left previous positions.

You may find out something the nanny didn't mention in the interview, such as short tenures, punctuality concerns, or misaligned approaches. These aren't necessarily deal-breakers, but they're things you deserve to know before making an offer.

How to avoid this: At Homebodies, we handle all reference checks as standard. We speak directly with previous employers, ask detailed questions, and look for patterns across multiple references. We also conduct DBS checks and verify qualifications. This thorough vetting process is one of the most important ways we reduce risk for our families.

How Homebodies helps you avoid these mistakes

Our matching process is designed to help you avoid these pitfalls. We get to know your family, then hand-pick 3-5 candidates who genuinely match your needs. By the time you meet them, we've already interviewed them, checked references, and conducted safeguarding checks.

We guide you through interviews and build proper paid trials into every placement. Plus, our support continues after placement to help navigate any challenges.

Naturally, even with thorough vetting, unforeseen situations sometimes arise - a nanny becomes unwell or personal circumstances change. We can't control these life events, but we support you through them, helping you find a replacement and providing guidance during transitions.

Making the right nanny hire

Hiring a nanny is a significant decision, and it's natural to feel anxious about getting it right. The families who make successful, long-term hires start their search early, look beyond CVs to genuine compatibility, invest time in proper trials, and work with an agency that provides genuine guidance.

If you're worried about making a mistake or you've had a difficult experience with a previous hire, we're here to help. Our process is designed specifically to reduce stress, minimise risk, and help you find the right nanny - not just any nanny - for your family.
