Why You Lost the Job: Mistakes Nannies and Babysitters Make in Interviews and on the Job

Before the Interview Even Starts

Your references are not optional and your mother does not count

If you cannot provide verifiable professional references from families who hired you in a paid capacity to care for their children, you are not ready to present yourself as a professional candidate. A reference from your mother, your aunt, your cousin, or anyone related to you by blood or friendship is not a professional reference. It is a gap being covered with a name.

This comes up more often than it should. Candidates who list family members as references, or who list references with no contact information, or who list people who do not answer when called, are signaling one of two things. Either their professional experience is not what they represented it to be, or they do not understand what professional standards in this industry actually look like. Neither is a good start.

Your references should be from families you worked for, who can speak specifically to your performance, your reliability, and your work with their children. Have them ready before you apply, not after you get the call.

“How to Write a Nanny Resume That Gets You Hired”

Read the job description again right before the interview
This sounds obvious. Most candidates do not do it.

A job description is not just a list of requirements. It is a window into what that family’s life actually looks like and what they are hoping to find in the person they hire. A family who mentions in their posting that they love to entertain friends and frequently host gatherings is telling you something about the household environment you would be walking into. A family who mentions date nights is telling you something about their priorities and their expectations around flexibility.

The candidate who reads that description carefully and comes into the interview prepared to speak to those specific details stands out immediately from the candidate who gives generic answers about their childcare experience. If the job description mentions entertaining, talk about your experience in those environments. Your ability to adapt your presence from primary caregiver during the day to composed, capable background support during a dinner party is a real skill and one worth communicating directly. If the description mentions date nights, address it naturally and set a clear, respectful expectation in the same breath. Something like: I noticed you mentioned date nights in your description and I just want you to know I am happy to support those, typically one or two a month works well for me as long as I have a week or two of advance notice. That kind of response tells the family you read what they wrote, you thought about it, and you are someone who communicates expectations clearly rather than letting them become assumptions.

The family is evaluating whether you are paying attention. The job description is the first test.

In the Interview: What Families Are Actually Noticing

Your appearance communicates before you say a word

Professional appearance in a childcare interview is one of the most consistently mentioned frustrations from both families and agencies, and it is one of the most easily corrected.

If you are interviewing for a full-time nanny position with a family, whether that interview is in person or on a video call, dress professionally. A suit, a blazer, something that signals you understand this is a professional engagement and you take it seriously. The candidate who shows up to a video call in a hoodie, in their car, with poor lighting and background noise, is telling the family something about their standards before the conversation has started.

This does not mean you need to show up on day one dressed the same way. Nobody expects you to change a diaper in a suit. Once you have met the children and the professional relationship is established, the dress code naturally adjusts to what the role actually requires. But for every formal interaction, the initial phone screen, the video interview, the first in-person meeting with the parents, dress in a way that makes you stand out from the other candidates rather than blend into the background.

First impressions in this profession are formed fast and they are hard to reverse. Use your appearance as one more tool to communicate that you are serious about the role.

Communication habits that undermine a strong candidate
How you communicate in an interview matters as much as what you say. A few specific habits come up repeatedly as frustrations for families and agencies evaluating candidates.

Interrupting. Even when nerves kick in and the impulse to fill silence is strong, wait for the other person to finish speaking before you respond. Interrupting signals impatience and a lack of active listening, neither of which is reassuring in someone you are considering trusting with your children.

Filler words. Everyone uses them occasionally and that is fine. A candidate who punctuates every sentence with um, like, or you know creates an impression of uncertainty even when the content of what they are saying is strong. It is worth being aware of and worth practicing before a high-stakes interview.

Being too casual. Warmth and approachability are genuine assets in a childcare professional. There is a difference, however, between being warm and personable and treating a professional interview like a casual conversation with a friend. The family is evaluating whether you understand the professional nature of the role you are applying for. Match their energy and register while still letting your personality come through.

Being bubbly is not a liability. Being bubbly without the professional foundation underneath it is.

Come prepared with something to say
A candidate who arrives at an interview with relevant examples ready, specific stories from their experience that speak to the family’s situation, stands out from a candidate who answers every question in the abstract.

If you worked with a family that frequently entertained and you managed the children during those evenings in a way that allowed the parents to be fully present with their guests, say so specifically. If you have experience planning age-appropriate activities around developmental milestones, describe what that actually looked like in practice. If you have handled a difficult behavioral situation with a child and navigated it well, have that story ready.

Families remember specific examples. They do not remember generic answers about being passionate about childcare. Remember this “Facts tell, stories sell.”

On the Job: Where the Real Mistakes Happen

The interview went well. Then Monday arrived.
The most frustrating hiring experience a family can have is not the candidate who bombs the interview. It is the candidate who impressed them completely and then revealed themselves to be an entirely different person once they were comfortable in the role.

Picture a family who hired a nanny through a reputable agency. Professional presentation, strong interview, good references. They are hired and things are going great, slowly they start to slip and slowly the initial big impressions fade. Now a few months in, eight hours a day across five days, the activities are coloring and painting, literally every day, that is it. Seventy-five degree weather outside, a backyard available, children with energy and curiosity and a developmental need for varied stimulation. Twenty minutes of sidewalk chalk across the entire week. Lunch dishes left in the sink every afternoon during nap time while the nanny sits on their phone. When the topic of the children’s laundry comes up, the response is direct. That is housekeeping, not a nanny’s job. *It absolutely should be a nanny’s job for children’s laundry. That said, you have every right as a nanny to set “your” standards. If you have zero interest in doing laundry, fine. State that upfront that you do not do laundry, but first don’t be surprised if they choose another candidate and second, don’t pawn off what industry standard should be onto another department. Housekeepers clean houses and often do parent laundry. If a family doesn’t want you doing laundry fine. In this case it was being lazy.

At the end of the day the kids say to their parents “I was bored”.

This has nothing to do with an interview. It has everything to do with the gap between who she presented herself as and what she actually delivered when nobody was grading her performance.

A professional caregiver plans the day with intention. They vary activities. They get children outside when the weather allows. They treat the spaces they use with basic respect. They understand that the standard does not drop because the parents are not in the room. The family is not there to watch. That is the entire point of hiring someone. They are trusting you to maintain the standard when they cannot see it.

Basic household competence
A babysitter or nanny who cannot prepare a simple meal for the children in their care is not prepared for the role. This comes up in family frustrations more than almost any other complaint. Not elaborate cooking. Not gourmet meals. The ability to make a simple lunch, clean up after it, and leave the kitchen in the condition it was found.

A caregiver who leaves the kitchen requiring significant cleanup after every shift, who cannot manage basic food preparation for children, or who treats any task adjacent to direct childcare as outside their responsibility is adding work to the household rather than reducing it. Most families are not asking for a chef. They are asking for a professional who understands that caring for children in someone’s home includes basic stewardship of that home.

If cooking is genuinely not a skill you have developed, address it honestly before accepting a role where it will be expected. A family who hires you believing you can manage meals and discovers on day three that you cannot is not just inconvenienced. They feel misled.

Leaving a mess
Related but worth stating separately. The physical spaces used during a shift should be left in reasonable order. Toys put away, surfaces wiped, dishes handled, laundry managed if that is part of the role. A caregiver who consistently leaves the household in a worse state than they found it is communicating something about their professional standards that no amount of warmth with the children can fully offset.

Not following house rules
Bedtime is eight o’clock. The parents come home at nine thirty and the children are awake watching television. Screen time has limits. The limits are not being observed. Certain foods are off limits. The packaging is in the trash.

These are not small things and they should not be treated as such. A caregiver who does not follow the household rules the family established is not making a judgment call that happens to differ from the parents. They are deciding that the family’s authority in their own home is optional when no one is watching. That is not a misunderstanding. That is a pattern, and patterns do not resolve without direct intervention.

Address deviations from house rules immediately and specifically. Give a caregiver who has otherwise earned your trust the opportunity to correct course. But do not mistake your reluctance to have an uncomfortable conversation for the problem being minor. It is not.

The Difference Between a Mistake and a Pattern

Every professional in this field has made a mistake. A schedule forgotten, a pickup that ran late, a rule overlooked on a genuinely difficult day. These things happen to people who are otherwise excellent at their work and deeply committed to the children they care for.

The mistake is not the problem. The pattern is.

A caregiver who makes an isolated error and responds with accountability, honesty, and a genuine adjustment in behavior is someone worth keeping. A caregiver who repeats the same mistake after feedback, who responds to correction with defensiveness, or whose performance consistently falls short of what was agreed to is showing you something about their professional character that good intentions cannot override.

Know the difference and respond to each accordingly. One conversation about a genuine mistake handled honestly is part of a normal professional relationship. The same conversation three times about the same issue is a different situation entirely.

A Word to Candidates Reading This

If you recognized yourself in any part of this article, that is useful information. Not a reason to feel discouraged but a reason to be honest about where the gaps are and what closing them actually requires.

The families described in this article are not unreasonable. They are parents who trusted someone with their children and felt that trust was not honored. The professional who shows up consistently, communicates clearly, follows through on what was agreed to, and maintains their standard whether or not anyone is watching does not generate these complaints. They generate referrals.

That is the professional this industry needs more of and the professional Tier One was built to find, verify, and connect with families who are ready to hire at that level.
