How to Answer Interview Questions About Working Across Time Zones From Nigeria

The time-zone question is one of the most predictable parts of a remote interview with a US, UK or European company, and Nigerian candidates often answer it badly. Some promise to work any hours. Others haven't worked out what "EST hours" means on a Lagos clock. This guide covers what interviewers are really testing, the clock maths you should do before the call, how to read the time-zone wording in a job ad, and sample answers to the questions you're most likely to get.

Quick answer

Answer time-zone questions in four parts. First, state your overlap window in both time zones ("3pm to 8pm Lagos, which is 9am to 2pm in New York"). Second, give one real example of working across a time difference. Third, explain how you keep work moving while the team is offline. Fourth, name your power and internet backup. Commit only to hours you can keep for years, not weeks.

What interviewers are really checking with time-zone questions

A hiring manager who asks "How do you feel about working our hours?" usually has three worries:

• Reliability. Will you be online when you say you will, in month 14 as well as week 1?
• Communication. When nobody is awake to ask, will your written updates be clear enough for work to keep moving?
• Sustainability. Will a 10pm finish wear you out and lead to you quitting after six months?

Companies that hire widely care about this a lot. Automattic, the company behind WordPress.com, says on its careers page that "collaboration across time zones is a key part of how we operate" and that it relies on "clear, thoughtful written communication". It also says most of its roles start with a Slack interview (as of October 2026). Some interviews test your written, asynchronous communication simply by being held in writing.

Asynchronous (async) work means people contribute at different times through written updates, documents, tickets and recorded videos instead of live meetings. If you can show you're good at async work, a five- or six-hour time difference stops looking like a risk.

Work out the time difference before the interview

Never work out the time difference during the interview. Do it the night before, write down the result, and give your answer in both time zones so the interviewer doesn't have to convert anything.

Nigeria uses West Africa Time (WAT), UTC+1, all year. Nigeria doesn't change its clocks, but the UK, Europe and the US do, so your overlap with them moves twice a year.

Sydney's seasons are reversed. Its 9am start falls at 11pm the previous evening in Lagos during the northern winter (Sydney's summer) and at midnight during the northern summer.

The table shows which conversations are easy and which are hard. A UK or European team overlaps with almost your whole working day. A US East Coast team overlaps with your afternoon and evening. A US West Coast or Asia-Pacific team gives you very little overlap unless one side works unusual hours. If a role needs full Pacific-time hours, say honestly whether you can do it.

The clock-change weeks that catch people out

The UK and the US change their clocks on different dates. According to GOV.UK, UK clocks go forward on the last Sunday in March and back on the last Sunday in October. In 2026 that was 29 March and 25 October, and in 2027 it will be 28 March and 31 October. The US National Institute of Standards and Technology (NIST) says US daylight saving time begins on the second Sunday of March and ends on the first Sunday of November.

For someone in Lagos, this means:

• New York is 5 hours behind you from the second Sunday in March to the first Sunday in November, and 6 hours behind for the rest of the year. As of October 2026, the next change is on 1 November 2026, when New York goes 6 hours behind.
• For a week or two each spring and autumn, London and New York are 4 hours apart instead of 5. If your manager is in London and the client is in New York, meetings can move by an hour without warning.

Mentioning this in an interview ("I keep a world clock for New York and London, because the US and UK change their clocks on different weeks") is a small detail, but it shows you've worked across time zones before or have prepared properly.

Read the job ad's time-zone wording first

Most time-zone questions follow from something written in the ad. If you misread the ad, your answer will be wrong too. Here's real location wording from remote job posts in the Hacker News "Who is hiring?" thread for October 2026, as collected on hnhiring.com:

These examples show how ads describe time zones. They don't confirm that any of these companies will hire someone living in Nigeria. A time-zone band and a list of eligible countries are separate rules. An xAI AI Tutor ad on Greenhouse shows the difference: it limits the role to the United States, United Kingdom, Canada and Australia, and says full-time positions "require working standard business hours in your local time zone" (checked October 2026). A Lagos time zone doesn't help if Nigeria isn't on the country list.

Before the interview, check the live ad for both rules. For more on the terms, see what EMEA means in a remote job description and what "worldwide remote" really means when you apply from Nigeria.

A four-part structure for any time-zone answer

Use the same four parts whatever form the question takes. We call it WPSB: Window, Proof, System, Backup.

1. Window. Give the hours you'll reliably be online, in both time zones. "3pm to 8pm Lagos, 9am to 2pm Eastern" is a commitment. "I can adjust" isn't.
2. Proof. Give one short, true example of working with someone who wasn't in your time zone. It can come from freelance work, a volunteer project, an online course cohort or a diaspora family business.
3. System. Explain how work keeps moving while you're offline, for example end-of-day handoff notes, clear ticket updates, recorded Loom walkthroughs or a shared doc of open questions.
4. Backup. Say what happens when NEPA takes the light or your fibre goes down, for example an inverter or solar setup, a second internet provider or a MiFi with a phone hotspot, and a phone that can join a call.

You don't need all four parts every time. A quick "Can you make a 4pm Eastern stand-up?" needs only the window. A behavioural question needs proof and system. Choose the parts that fit the question.

Common time-zone interview questions, with sample answers

Each sample answer below is hypothetical. Change the details so everything you say is true for you. Interviewers dig into examples, and an invented story usually falls apart on the second follow-up question.

"Are you comfortable working US hours?"

This question is really about how many of their hours you'll cover, and whether you'll last.

Example (hypothetical), for a New York-based SaaS company: "Yes, with a clear structure. I'm in Lagos, which is 6 hours ahead of New York in winter and 5 in summer. I'd work from noon to 8pm my time, which gives you five hours of live overlap in winter, 9am to 2pm Eastern, and six in summer. I'd use the morning before your team comes online for focused work and for clearing anything you left for me overnight. If a meeting has to run later now and then, I can do it. I just don't want to promise a 2am finish every day and then not keep to it."

That answer gives the numbers, shows you understand the clock changes, and turns your earlier start into an advantage.

"How much overlap can you give us?"

Give a number of hours and the exact window, and ask what they normally expect. Many teams only need a few shared hours for meetings and quick questions. The rest of the day can be async.

Example (hypothetical), for a London-based agency: "All of it, really. London is one hour behind Lagos right now, so your 9 to 5 is my 10 to 6. In summer we're on the same time. Is there a core-hours window your team works to?"

For a European team the answer is almost always easy, so keep it short. Don't add caveats nobody asked for.

"Tell me about a time you worked with someone in a different time zone"

This is a behavioural question, so answer it as a short story: the situation, what you did, and the result.

Example (hypothetical): "When I was freelancing as a virtual assistant, my client was in Toronto, five or six hours behind me depending on the season. She'd send requests late in her evening, which was the middle of my night. I set up a shared tracker. Every morning I worked through her overnight requests, and by 2pm Lagos, which was the start of her day, I'd posted a short update: what was done, what was blocked, and one question per blocked item. She told me she liked starting her day with an inbox that was already sorted. We moved from a two-week trial to a monthly retainer."

Only say "we moved to a retainer" or "she told me" if it actually happened. If your proof is smaller, such as a group project with a coursemate in Canada, use it anyway. A true small example is better than an invented big one.

"How do you keep work moving when the team is offline?"

This is the system part of the framework, and it's where strong candidates stand out. Describe a habit, not a personality trait.

Example (hypothetical): "Before I log off, I write a handoff note in the team channel: what I finished, what's in progress, and anything I'm waiting for, with the exact question that needs answering. If I'm stuck on something at 6pm, I don't wait until tomorrow to ask. I write the question with enough context that someone can answer it in one reply while I'm asleep, and I have a second task ready so I'm never just waiting."

If the company works in writing first, as Automattic says it does, this answer speaks directly to how they work.

"What happens if your power or internet goes out during a meeting?"

Many interviewers who have hired in Nigeria before will ask this, and some will wonder about it without asking. If they don't raise it, mention it briefly when you describe your setup. Nobody expects perfect infrastructure. They want to see you have a plan.

Example (hypothetical): "My setup has an inverter with enough battery to run my laptop and router through an outage, plus two internet connections: home fibre, with a MiFi from a different network as backup. If both fail, I can join from my phone on mobile data. If I ever miss a meeting, I message the team within minutes and catch up from the recording or notes. In practice my backup kicks in before anyone notices."

Don't overclaim. If you don't have a backup yet, say what you're putting in place and when it will be ready, then do it before your start date. Our guide on staying productive when your internet is unreliable covers setups in more detail.

"Would you be willing to work nights or be on call?"

Answer honestly, because this sets your working life for as long as you're in the job. If the role is US West Coast customer support, "on call" can mean working from midnight to 6am Lagos time.

Example (hypothetical): "I can cover on-call shifts on a rota, and I'd want to know the expected frequency and the response time. For regular hours, I'd rather keep my main shift ending by 11pm Lagos, because I know I'll do better work over the long run that way. If the role needs full Pacific hours every day, I'd like to discuss that openly now rather than find out after I start."

A recruiter would much rather hear this now than lose you three months after you start. For the longer-term side of this, see how to manage different time zones without burning out.

"What time is it for you right now?"

This sounds like small talk, but it's also a quick test. Answer immediately and correctly in both time zones: "It's 4pm here in Lagos, 10am for you in New York." Fumbling the answer suggests you haven't worked across time zones before.

Answers that make interviewers doubt Nigerian candidates

The same mistakes come up again and again. Each one is easy to fix.

• "I can work any hours." It sounds keen, but an experienced manager hears "hasn't thought about it". Give a window instead.
• Getting the conversion wrong. If you say "your 9am is my 2pm" in December, you're an hour off. Check which side of the clock change you're on.
• Converting into their time only. Give both. It makes scheduling easier and shows care.
• Ignoring the country list. A good time-zone answer doesn't help if the role is limited to residents of certain countries. Check eligibility before the interview, not after. Our page on why some remote jobs are not open to Nigerians explains the usual reasons.
• Hiding infrastructure risk. If an outage during the interview exposes it, you lose trust you can't easily get back. Mention your backup plan first, briefly and calmly.
• Promising hours you'll later resent. Saying "yes" to 6pm to 2am Lagos time just to get the offer is how people end up quitting six months in. Be honest early.

How to answer if you've never worked across time zones

Plenty of first-time remote candidates have no time-zone experience. You can still give a credible answer by drawing on related experience and showing a clear plan.

Sources of proof that count:

• Freelance or volunteer work for anyone abroad, even unpaid
• Online courses or bootcamps with live sessions on another continent's schedule
• Open-source contributions, where reviewers are spread around the world
• Coordinating with relatives abroad on something practical, like organising a family event or a business task (keep it short)
• A Nigerian job where you dealt with a foreign head office, supplier or client

Example (hypothetical): "I haven't had a fully remote job yet, but for the past four months I've attended a data analytics course that runs live sessions at 2pm Eastern, 8pm my time. I haven't missed one, and I submit my assignments by their Friday deadline, which falls on my Saturday morning. It's taught me to plan around someone else's clock."

Agree the schedule before you accept the offer

The interview is also your chance to find out what the job really requires. Ask these questions near the end, or at the offer stage:

1. What are the team's core hours, and how many of them do you need me online for?
2. When are the regular meetings, such as stand-ups, planning and one-to-ones, in your time zone?
3. Is on-call or weekend cover part of the role, and how often?
4. Do meeting times move when your clocks change, or do they stay fixed in my time?
5. How quickly do you expect replies to messages outside the core hours?

Get the answers in writing if you can. An email that says "core hours 9am to 1pm Eastern" protects you later if someone expects you online at midnight. More questions worth asking are in questions to ask before accepting a remote job offer.

Frequently asked questions

How many hours of overlap do US remote employers usually expect?

There's no standard figure. Each company sets its own, so look for the number in the ad and ask if it isn't there. Many teams need only part of the day as shared live time and handle the rest asynchronously. Some ads, such as those listing "EST hours", expect your whole day to fall within US Eastern working hours.

What time is 9am EST in Lagos?

9am EST is 3pm in Lagos. In summer, when New York uses EDT (from the second Sunday in March to the first Sunday in November), 9am New York time is 2pm in Lagos. Nigeria stays on UTC+1 all year, so only the US side changes.

Is it better to say I'm flexible with hours?

No. Give a specific window instead. "I'm flexible" sounds vague and can trap you into hours you can't keep. Something like "noon to 8pm Lagos, covering your morning" is easier for the interviewer to trust and holds you to a realistic schedule.

Can I work UK hours from Nigeria without changing my schedule much?

Yes. Lagos is on the same time as London in summer (BST) and one hour ahead in winter (GMT). A UK 9am to 5pm day is 9am to 5pm or 10am to 6pm in Lagos, which makes UK and European roles the easiest time-zone fit for Nigerians.

Should I mention power cuts in a remote interview?

Yes, but briefly, and as part of your setup rather than as a problem. Say what backup you have (an inverter or solar, a second internet connection, and your phone as a last resort) and what you'd do if a meeting dropped. Interviewers who know Nigeria will be reassured. Ones who don't will see you plan ahead.

Does a matching time zone mean the company will hire someone in Nigeria?

No. Time zone and eligible countries are separate requirements in most job ads. A role can accept "GMT-8 to GMT+2" and still be open only to residents of certain countries, so check the location section of the live ad, or ask the recruiter, before you invest in interviews.

How should I prepare for a time-zone question the night before?

Write down the interviewer's time zone, the current difference from Lagos, your proposed overlap window in both zones, one true example of working across a time difference, and your backup setup. Five lines on a sticky note will cover almost any version of the question.

Key takeaways

• Interviewers who ask about time zones are testing reliability, written communication and whether you can keep the schedule up, not just your willingness.
• Lagos stays on UTC+1 all year. London, Europe and the US change their clocks, on different dates, so check which side of the change you're on before you quote times.
• Answer with a specific overlap window in both time zones, a true example, your handoff system and your power and internet backup.
• Read the job ad for two separate things: the time-zone band and the list of eligible countries.
• Commit only to hours you can keep long term, and get the agreed core hours in writing before you accept.
