Your interview is at 3 p.m. The light goes at 2:40, your Wi-Fi router dies with it, and your phone shows one bar. Most people in that spot panic. A prepared candidate switches to a backup in under two minutes and carries on. This guide shows you how to build that backup and how to run the call itself.
Employers abroad know that connections drop. What they judge is how you respond. A calm, organised person who reconnects fast often beats a nervous person with perfect video.
Step 1: Find out the format before you do anything else
When the recruiter sends the invite, check which tool the call uses (Zoom, Google Meet, Microsoft Teams or something else). Then ask two short questions by email:
- Is video required, or is audio acceptable if my connection is unstable?
- Who should I contact, and by what channel, if I drop off the call?
Asking this sounds professional, not weak. It also gives you a named contact and a fallback plan before the day arrives.
Step 2: Build two independent connections
Two connections that share one weak point are not a backup. If your Wi-Fi and your phone hotspot both depend on the same network tower, one outage ends both.
| Setup | Strength | Weakness |
|---|---|---|
| Home broadband or fibre | Stable when it works | Needs power for the router; fails when the line is cut |
| Phone hotspot on network A | Works through a power cut if the phone is charged | Tower congestion in the evening |
| Second SIM on network B | Covers a network-specific outage | Needs a separate data bundle |
| Tethering via cable | More stable than wireless hotspot, and saves battery | Needs a laptop port and the right cable |
Practical choice: use your main connection plus a SIM from a different network. Test which network has the better signal in the exact spot where you will sit. Signal can differ between one corner of a room and another. Check the network coverage maps or just test it by running a call with a friend.
Step 3: Protect against power cuts
- Charge your laptop and phone fully the night before.
- Keep a power bank charged and cabled to the phone you use for the hotspot.
- If you have an inverter or UPS, check that your router is plugged into it, not just your laptop.
- If you can't guarantee power at home, book a quiet spot elsewhere, such as a co-working space or a relative's place with a generator, and confirm access in advance.
A small UPS for a router is a modest cost compared with losing a job opportunity. Check current prices from local sellers rather than relying on a number you saw months ago.
Step 4: Test the actual call, not just a speed test
A speed test tells you download speed. A video call is more sensitive to upload speed and stability. Two days before, do this:
- Run a test call on the same platform with a friend, at the same hour as your interview.
- Ask them whether your voice cut out or your video froze.
- Close other apps, pause cloud backups and updates, and ask others in the house to stay off heavy streaming during your slot.
- Turn off HD video in the app settings and keep your camera at standard quality.
Test at the same time of day because many networks slow at peak evening hours.
Step 5: Lower the data demand during the call
Audio is the part of the interview that matters most. If the picture is fuzzy but they can hear you clearly, you are fine. Protect the audio:
- Use wired earphones with a microphone; they usually sound clearer than a laptop mic and avoid Bluetooth battery or lag problems.
- Turn off your camera if the connection is poor, after saying politely that you are doing so to keep the audio clear.
- Don't share your screen unless asked. If you must present, send the slides by email beforehand as a backup.
- Stay close to the router or window.
Step 6: Script the first 30 seconds if things go wrong
Decide in advance what you will say. Rehearse it aloud so you don't freeze.
"Sorry, my connection is unstable. I'm switching to my backup and will rejoin in a minute. If I'm not back, I'll email you straight away."
Then do exactly that. If you drop, rejoin within two minutes. If you can't, send a short email: apologise, state that you have a backup, and offer to continue by phone call or reschedule. Keep it factual, without long excuses.
Step 7: Worked example (hypothetical)
Imagine Amaka, a customer support applicant in Lagos, has an interview at 4 p.m. on Zoom with a UK company. Her home Wi-Fi is usually fine, but it fails often when power goes out.
- Two days earlier she emails the recruiter to ask if audio-only is acceptable and for a phone number in case of a drop.
- She does a test call with a friend at 4 p.m. and finds her second SIM gives clearer audio than the Wi-Fi in her room.
- On the day she charges everything, sets the hotspot ready on the second SIM and connects the router to a small UPS.
- Ten minutes into the interview, the Wi-Fi drops. She says her prepared line, switches to the hotspot, and rejoins in 90 seconds.
The interviewer sees someone who plans. That is a useful signal for a remote role.
Common mistakes
- Testing only once, at a quiet hour. Test at the interview time.
- Relying on one network. Two SIMs from different providers cover more failures.
- Forgetting the router's power. A charged laptop doesn't help if the router is off.
- Running low on data mid-call. Load more data than you think you need and check your balance beforehand.
- Hiding the problem. Say early that you've had a drop. Silence looks worse than a short apology.
- Not preparing answers. Technical prep doesn't replace knowing your story. Practise your answers about your experience and why you want the role.
Check the interview itself is real
Before you spend on data or a venue, confirm the employer is genuine. Be wary of anyone who asks for payment for an interview, a "training kit" or software. Our guide on spotting a fake remote job offer covers the warning signs. If the role involves US or UK hours, read our time zone guide so you can answer scheduling questions with confidence. And make sure your CV is ready for international roles before the call.
Country notes
Network quality and power vary by city and even by neighbourhood in Nigeria, Ghana, Kenya and South Africa. South Africa's load-shedding schedules are published, so you can plan your slot around them. In other countries, ask neighbours which network is steadiest in your area. In every country, the principle holds: two independent connections and a power plan.
Frequently asked questions
Should I turn my camera off during an interview?
Only if the connection forces you to. Start with video on, and if it freezes, say you're turning it off to protect the audio. Many interviewers accept that.
Can I ask to reschedule if my power or network is bad that day?
Yes, as early as you can, with a brief reason and two alternative times. Last-minute changes more than once look unreliable.
Is a phone interview better than video?
Audio uses far less data, so it is safer on a weak connection. Offer it as an option only if video fails.
How much data does a video call use?
It varies by app and quality settings, so check your app's settings and run a test call while watching your data balance.
Your next step
Today, put your interview time on a test call with a friend, using your second SIM. Note which connection sounded clearer, and write your backup line on paper beside your laptop.
Always apply through the employer's official website or verified channels. Genuine employers never ask applicants to pay for a job, training, or an interview.
