Fix: "slow network" warning during pre-flight

If the platform warns you about a slow connection, the interview will still work — but here are the quick wins to get a faster, more stable link.

Key takeaways

  • You can still take the interview with a slow connection — it just feels laggier.
  • Aim for 5 Mbps up and down, with under 100ms latency.
  • Wired ethernet is the most stable. 5 GHz Wi-Fi near the router is second-best.
  • Quitting bandwidth-heavy apps (cloud sync, video apps, downloads) before you start often fixes it.

If the platform shows a yellow or red warning about a slow connection during the pre-flight checks, you have a choice: proceed anyway (it'll work, just laggier) or fix it before you start. This article covers the quick fixes.

What the warning actually means

The pre-flight runs a 10-second speed test against the interview servers. We measure three things:

  • Download speed. How fast the AI's voice audio can reach you. Below 1 Mbps gets a hard warning.
  • Upload speed. How fast your microphone audio reaches the AI. This matters more than download, because the AI cannot answer until it has heard you. Below 1 Mbps gets a hard warning.
  • Latency. Round-trip time. High latency makes the AI feel slow to respond. Above 200ms gets a warning.

You will still be allowed to start the interview at any speed, but if any of the three is bad, you will see a warning.

Quick fixes in priority order

1. Close bandwidth-heavy apps

Most commonly the issue is not your internet — it's that other apps are using it. Quit:

  • Cloud storage (Dropbox, Google Drive, OneDrive, iCloud) — they sync constantly
  • Streaming apps (Spotify, YouTube in another tab, Netflix on a phone on the same Wi-Fi)
  • Video calls in another window (Zoom, Teams, Meet)
  • OS updates (macOS and Windows both auto-download in the background)
  • Email clients that are syncing large attachments
  • Any active torrent or download manager

Quitting these gives the interview tab the full pipe. Then re-run the speed test — you should see a noticeable jump.

2. Move closer to the router or switch to wired

Wi-Fi is the most common bottleneck. Quick wins:

  1. If your laptop has an ethernet port (or a USB-C adapter), plug in directly to the router.
  2. Otherwise, sit in the same room as the router during the interview.
  3. If your router supports both 2.4 GHz and 5 GHz bands, connect to the 5 GHz one. (5 GHz is faster and less congested; 2.4 GHz reaches further but is slower.)
  4. Disconnect other devices from the same Wi-Fi if you can — your housemate's Netflix on a TV will eat into your bandwidth.

3. Use your phone as a hotspot

If your home Wi-Fi is genuinely bad, mobile hotspots often work surprisingly well — modern 4G/5G easily exceeds 5 Mbps. Turn on your phone's hotspot, connect your laptop to it, and re-run the speed test.

TIP

If you use a mobile hotspot, sit near a window or wherever your phone has the best signal. Indoor cellular reception varies wildly. A bar or two of signal will work; one bar or below may not.

4. Restart the router

Old-school but it works — routers occasionally get into a bad state where speeds tank. Unplug it for 30 seconds, plug it back in, wait 90 seconds for it to fully come up, then run the speed test again.

If none of the above works

Go ahead and start the interview anyway. The AI is built to tolerate poor connections — it will pause more often, the recruiter will see longer gaps between AI questions and your answers in the recording (we annotate these as 'network pauses', not as candidate hesitation), and the transcription quality will be slightly lower.

If, mid-interview, the connection drops badly enough that the AI can no longer hear you for an extended period, the interview ends and is marked as incomplete. Contact the recruiter — they can re-issue an invite.

Frequently asked questions

Will a slow connection ruin my interview?

Not ruin — but it will feel slower. The AI may pause more often as your audio uploads. Long answers may take a moment to be acknowledged. If your bandwidth is genuinely awful (under 1 Mbps), the AI may sometimes mis-hear because chunks of audio arrive corrupted. In practice, even a coffee-shop Wi-Fi works.

I can do speed tests fine but RecruitMe still warns me. Why?

Speed tests measure peak bandwidth to nearby servers. RecruitMe measures sustained bandwidth and latency to the actual interview servers, which is a more honest indicator for a live conversation. The warning means your sustained throughput is below threshold even if your peak is fine.

Can I switch networks mid-interview?

Not safely. If your laptop changes networks (e.g. Wi-Fi drops and switches to a mobile hotspot), the interview connection drops with it. Pick the best network before you click Start and stick with it.
