How to hire an assistant or office manager: role, ad and interview

Cover image with the title How to hire an assistant or office manager and a document icon in sage green and sand

To hire an assistant or office manager, list the tasks you want to hand over, group them by skill, decide the hours and the level of trust, write a clear job description, advertise it with the pay range, and test the real skills with a short task such as a calendar puzzle, an email draft or a small spreadsheet. Keep the process fair, and plan the first month so that the person can take over tasks step by step.

Key takeaways

  • Start with a task audit: write down everything you want to hand over and how long each task takes.
  • Choose between an assistant (supports you) and an office manager (runs the office). They are different jobs.
  • Test judgement and organisation with a short, realistic exercise.
  • Be clear about confidentiality, access to systems and data protection from the start.
  • Plan a staged handover: show, do together, then hand over with review.

Assistant or office manager?

Titles in this area are used loosely. Before you write an ad, decide what you need. The two main roles are different, and so are the skills and the pay.

AspectAssistant (executive or personal)Office manager
Main focusSupports one person: calendar, email, travel, follow-upRuns the workplace: suppliers, equipment, health and safety, visitors, admin, sometimes HR support
Key skillsDiscretion, written communication, calendar management, anticipationOrganisation, supplier management, budgets, practical problem solving, people skills
Who they work withMostly youThe whole team, suppliers, visitors
Typical riskBecomes a bottleneck for one person’s tasksRole grows into many unrelated jobs
TestEmail, calendar and prioritisingSupplier plan, budget, handling an urgent issue

If you need both, consider whether one person can do both at the start, or whether you should begin with one and add the other later. A role that mixes both can work in a very small company if you define priorities. See how to write a job description for a role that does not exist yet.

Step 1: Run a task audit

For one week, write down every task you do that someone else could do. Note the time each takes and how often. Then group the tasks.

GroupExamplesHours per week (your estimate)
Calendar and emailScheduling, filtering, drafting replies, reminders
Travel and eventsBooking, itineraries, expenses
Finance supportInvoices, receipts, expense forms, supplier payments (with access controls)
OfficeSupplies, equipment, post, cleaning contracts, safety checks
People supportOnboarding setup, contracts filing, holiday calendar
Customer supportFirst reply, forms, bookings
ProjectsResearch, document formatting, meeting notes

Add the hours. If the total is below ten hours a week, consider a part-time role or a freelancer, and read employee or contractor. If it is above 30 hours, the job is full-time. Compare the cost with your own time using the cost worksheet.

Step 2: Decide trust, access and data

Assistants and office managers see sensitive information: emails, contracts, bank details and personal data. Decide before you hire what access the person will have, and put rules in writing.

  • Which accounts they can view or manage
  • Whether they can make payments, and what limits apply
  • How passwords and shared accounts are handled; use a password manager, not shared notes
  • What counts as confidential, and a confidentiality clause in the contract
  • Data protection duties. In the UK and EU, the person will handle personal data and needs training. See the ICO employment guidance
  • Checks you plan to make, where the law allows and the role needs it. Apply the same checks to every finalist

Step 3: Write the job description and ad

Use the seven-part method from the new-role guide: problem, outcomes, tasks, must-haves, nice-to-haves, context, unknowns. For an assistant, outcomes might be “calendar is up to date with no double bookings” and “email replies within one working day”. For an office manager, outcomes might be “supplier contracts reviewed each year” and “safety checks completed on time”. Choose three to five must-haves that you can check, such as “wrote business emails daily in the last role” or “managed supplier orders”. Avoid proxies such as years of experience that are not needed. See how to write a job ad that attracts the right applicants.

Step 4: Screen and interview

Must-haveQuestionWhat a strong answer shows
OrganisationTell me how you plan a week with many changes. Give a real example.A method, tools, priorities
Written communicationDescribe a difficult email you wrote on someone’s behalf.Clarity, tone, result
DiscretionTell me about a time you handled confidential information. What did you do?Care, rules, judgement
InitiativeTell me about something you improved in a past role without being asked.Action and result
Working with a busy personHow do you work with someone who changes priorities often?Calm, questions, flexibility
Practical problem solvingThe printer breaks before a client visit. What do you do?Steps, priorities, communication

Use the same questions for every candidate and a simple scorecard. Learn the method in our guides on the first interview and the interview scorecard. Do not ask about family plans, health, age or other protected topics. See what you can and cannot ask.

Step 5: Test the skills with a short task

A 30 to 45 minute exercise gives strong evidence. Use made-up data and tell candidates the time limit.

TaskWhat it testsScoring points
Calendar puzzle: five meetings, three time zones, two conflicts. Find a schedule and write a short email to confirm.Planning, attention to detail, written clarityNo conflicts, correct time zones, clear email
Inbox triage: ten fictional emails; mark the urgent ones, draft two replies, list questions for the manager.Priorities, judgement, toneRight order, polite and short replies, good questions
Small spreadsheet: fix three errors in a fictional expense sheet and add a total.Accuracy, basic toolsErrors found, formulas correct
Supplier choice: compare three fictional quotes and recommend one.Judgement, simple analysisClear comparison, assumptions stated

Keep the task short, paid if long, and fair. See how to assess skills with a work sample test.

Step 6: Check references and make the offer

Ask referees about reliability, discretion, accuracy and how the person handled pressure. See how to check references. Then make the offer with clear hours, duties and confidentiality terms. See how to make a job offer.

The first month: staged handover

StageWhat happensYour role
1. ShowExplain the task, why it matters and how you do itDemonstrate; give a checklist
2. Do togetherThe person does it while you watchGive feedback
3. Do with reviewThe person does it; you check the resultReview quickly
4. OwnThe person owns the task; you check weeklyTrust and spot-check

Write a short handbook as you go: where files are kept, who the key suppliers are, how you like emails written. The new person can update it, and it helps the next hire. See the first 30 days onboarding plan.

A worked example (fictional)

This example is invented. A founder of a six-person design studio spends about 12 hours a week on admin: scheduling, invoices, supplies and client emails. She runs a task audit and decides to hire a part-time studio coordinator for 20 hours a week. She writes outcomes: invoices sent within two days of project milestones, calendar free of conflicts and a monthly supplier review. She uses a 40-minute inbox triage task and the same six interview questions. The chosen candidate shows careful planning and clear email style. In the first month the founder uses the four-stage handover. By week four the coordinator owns the calendar and invoices. The founder reviews invoices weekly for two months. After 90 days the founder has about 10 more hours a week for client work.

Pay, hours and growth

Pay for assistants and office managers varies widely by country, city and level of responsibility. Do not guess. Check current local sources such as national statistics or labour market information, and compare advertised pay for similar roles in your area. In the US, the Bureau of Labor Statistics publishes occupation data in its Occupational Outlook Handbook. In the UK and EU, check your national statistics office and the legal minimum pay on GOV.UK or the equivalent source. Set a range, write it in the ad where allowed or required, and offer within it.

Be honest about growth. If the role can grow into a coordinator or operations role, say so, with the conditions. If it cannot, do not promise it. People stay when the work is clear, the pay is fair and they see a path to learn. A training budget or a named course can mean more than a vague promise.

Part-time and shared options

OptionFits whenWatch out for
Part-time employeeYou need steady cover, 10 to 25 hours a weekSet clear hours and a backup for holidays
Shared assistant between two foundersYou each need a few hoursAgree priorities and who decides conflicts; put it in writing
Freelancer or virtual assistantTasks are separable and the person works with their own toolsCheck status rules and data protection. See employee or contractor
Temporary coverA busy period or leave coverPlan the handover and keep access limited

Whatever option you choose, write down the tasks, hours, confidentiality rules, review dates and the way you will give feedback. A short written agreement reduces most misunderstandings.

How to review the role after three months

  1. Compare the task list with what the person actually does.
  2. Ask the person which tasks take the most time and which they would change.
  3. Review the outcomes: calendar conflicts, invoice timing, supplier issues, errors.
  4. Decide which tasks to add, move or remove.
  5. Update the job description and agree changes in writing.

Roles like this grow quickly. A short review prevents drift and keeps both sides clear about what is expected.

Finally, think about cover. If the person is ill or on holiday, who answers the calendar and the post? A shared checklist and a named backup keep the office running. Write the checklist while the person is new and fresh, because they notice steps that others have forgotten. Update it every quarter.

Frequently asked questions

What is the difference between an assistant and an office manager?

An assistant supports one person or a small group with calendar, email and tasks. An office manager runs the workplace, including suppliers, equipment and administration.

Should the role be full-time or part-time?

Add up the task hours from your audit. Under about ten hours a week, consider part-time or a freelancer. Above 30 hours, plan a full-time role.

How do I protect confidential data?

Limit access by task, use a password manager, add a confidentiality clause, train the person on data protection and review access regularly.

What test should I use?

A short, realistic task such as inbox triage or a calendar puzzle, with a time limit and a scoring guide.

Can I hire a virtual assistant?

Yes. Check the status rules in employee or contractor, and set data protection terms with the provider.
