Video interviews now cover most of the initial and technical screening in tech hiring. The setup and approach that work for a live Zoom screen are different from what gets you through an async one-way interview scored by an AI system. Both require preparation that goes beyond a tidy background.
Who this is for
This guide is for software engineers, TPMs, and other tech candidates who have video interviews coming up in any format: live video on Zoom, Google Meet, or Teams; or async one-way platforms like HireVue, Spark Hire, or Willo. If you are entering the interview stage after submitting applications through a job tracker or job board, video is almost certainly your first live interaction with the company.
What is the difference between a live and async video interview?
Live video interview: You and the interviewer are both on camera simultaneously. The format mirrors an in-person interview except that both sides manage audio, video, and connection quality on their own hardware. The interviewer evaluates you in real time.
Async one-way video interview: The platform presents questions one at a time with a preparation window (typically 30-60 seconds) followed by a recording window (typically 2-3 minutes per answer). You record your responses; no interviewer is present. A recruiter, hiring manager, or AI scoring system reviews the recordings later.
The key distinction is audience. In a live interview, the interviewer can adjust: ask follow-ups, signal when to move on, ask you to expand. In an async interview, the recording is the entire interaction. You cannot course-correct, and there is no feedback loop.
Async one-way video has become the standard first screen at many tech companies because it lets hiring teams review candidates across time zones without scheduling overhead. For candidates, this means treating a two-minute async recording with the same preparation investment as a live 45-minute screen.
Industry perspective
"According to the Stack Overflow 2024 Developer Survey, 42% of professional developers work fully remote and another 26% work in a hybrid arrangement, meaning most technical interviews for developer roles now take place via video by default."

What setup matters most for a technical video interview?
Camera: Position your webcam at eye level. A camera angled up from a laptop on a desk creates an unflattering angle and makes it harder to maintain eye contact. Stack books or use a stand to bring the camera to face height. During the interview, look at the camera lens, not at the interviewer's face on your screen. The difference in perceived eye contact is significant to reviewers watching the recording.
Lighting: One source of natural or soft artificial light should face you from slightly to the side, not from behind. A window behind you creates a silhouette. A ring light or a desk lamp pointed at your face from 18-24 inches away at a slight angle eliminates the most common video interview lighting problems in under five minutes.
Audio: Built-in laptop microphones pick up keyboard noise, fan noise, and room echo. A wired earbud with a microphone (including the basic ones that came with a phone) produces significantly cleaner audio than a laptop microphone. For technical phone screens or any high-stakes interview, even a $20 USB microphone is a meaningful upgrade. Test your audio before every interview by recording a short clip and listening back.
Background: A plain wall or a bookshelf is sufficient. Virtual backgrounds are acceptable but can pixelate around hair and hands at lower bandwidth, which creates visual noise. If your physical background is usable, prefer it.
Internet: Wired Ethernet eliminates the variability of Wi-Fi drops mid-answer. If you cannot use a wired connection, close all other applications consuming bandwidth before the interview starts.
How do async video interviews get scored?
Async video interviews at companies using HireVue, Spark Hire, or similar platforms are reviewed either by recruiters watching playback at 1.5-2x speed, or by AI scoring systems that analyze your response content.
Modern AI video scoring (as of 2021 and later) focuses on speech content, word choice, and answer structure rather than facial analysis. HireVue removed facial analysis from its platform in 2021 following scrutiny over accuracy concerns. Current AI scoring evaluates: whether your answer addresses the question asked, competency coverage (did you demonstrate the specific behavior the question is testing), language clarity, and verbal filler frequency.
For the AI scoring layer specifically, answer structure matters more than in a live interview:
First five seconds: State the situation or problem immediately. Do not start with "So, um, great question." Start with the context. "I was working on a payment service migration with a hard compliance deadline."
STAR format compliance: Situation, Task, Action, Result. AI scoring systems for behavioral questions are calibrated against this structure. An answer that describes a situation and action but never states a measurable result is scored lower than one that completes the loop.
Pace: Speak at a measured pace. Speaking too fast compresses your answer and sounds nervous in playback. Speaking too slowly leaves unused time at the end of your recording window, which fills with silence. Aim for 140-160 words per minute.
Time management: Async platforms show you a countdown timer. Target using 80-90% of the allotted time. Finishing with 45 seconds remaining signals an incomplete answer. Cutting off because you ran out of time signals poor preparation.
What happens when tech fails during a live interview?
70% of candidates have experienced a technical problem during a video interview. Recovery behavior affects the impression you leave as much as the failure itself.
Audio drops: Stop speaking immediately when you notice the interviewer cannot hear you. Type in the chat: "I think my audio dropped - can you hear me?" Do not continue speaking into silence for 30 seconds and then apologize. The faster you surface the problem, the faster it gets resolved.
Connection instability: If the call is degrading, offer to rejoin: "I'm getting some connection issues on my end - is it okay if I drop and rejoin quickly?" Most interviewers prefer a clean reconnection to a degraded call.
Platform failure: Have the interviewer's email in advance. If the platform completely fails, email immediately: "Platform dropped on my end - is there a dial-in or backup link?" Candidates who handle tech failures efficiently demonstrate exactly the kind of composure and problem-solving the interview is also evaluating.
Camera failure on async platforms: Many one-way platforms let you re-record within the allotted time. If the platform does not permit re-recording and your response had a serious technical failure, email the recruiter after completing the session to explain and ask if they can reopen one question.

Key takeaways
Async video interviews are scored on content structure, not just communication style
AI scoring systems on platforms like HireVue analyze whether your answer addresses the question, whether it demonstrates the competency being tested, and whether it follows a complete structure. Starting strong, using STAR format for behavioral questions, and using 80-90% of the allotted time are measurable factors in the score.
Camera at eye level changes how eye contact reads on video
Looking at your camera lens rather than the interviewer's face on screen is the single highest-impact setup adjustment for live interviews. It requires placing the camera at face height, which almost always means raising a laptop. Five minutes of setup before a live interview is worth the effort.
Audio quality matters more than most candidates assume
Built-in laptop microphones introduce fan noise, keyboard clicks, and room echo. A wired earbud with a microphone eliminates the most common audio problems without any additional cost. For a technical screen that may last 90 minutes, degraded audio creates compounding fatigue for the interviewer reviewing the recording.
Tech failures recover faster when you surface them immediately
Candidates who catch and communicate audio or video problems within the first few seconds of them occurring control the recovery narrative. Candidates who continue speaking into silence or ignore instability for several minutes leave the interviewer to manage the problem. Composure during a live technical failure is itself part of the evaluation.
Frequently asked questions
Should I use a virtual background for a video interview?
A clean physical background is preferable to a virtual one. Virtual backgrounds can pixelate around hair and hands at lower bandwidth, creating visual distraction. If your physical background is unusable, a plain virtual background in a neutral color is acceptable. Avoid custom or animated virtual backgrounds for any professional interview.
How early should I test my setup before a video interview?
Test your audio, video, and internet connection 30 minutes before the interview starts. Use the platform's own test feature if it has one, or record a short video of yourself speaking and play it back. Testing five minutes before leaves no time to resolve problems if something is wrong.
How long should each answer be in an async video interview?
Use 80-90% of the allotted time per question. If the platform gives you 2 minutes per answer, target 90-110 seconds. Answers that end 45 or more seconds early typically lack a result or adequate context. Answers that run exactly to the limit, or over, suggest poor pacing.
What should I wear for a video interview?
Dress at the same level you would for an in-person interview at that company. For most tech companies, business casual is appropriate for initial screens; more formal for late-stage interviews. Avoid high-contrast patterns or all-white tops, which can cause exposure problems on camera.
How does an async video interview differ from a phone screen?
A phone screen is a conversation. You can ask clarifying questions, get follow-up prompts, and read the interviewer's reactions. An async video interview is a monologue. You deliver complete, self-contained answers without feedback. The preparation required is closer to giving a presentation than having a conversation: you need to structure your answers in advance and deliver them clearly without a cue to keep going or wrap up.
Bottom line
- Live video and async one-way interviews require different preparation strategies. Async requires complete, structured answers delivered without feedback.
- Camera at eye level, front lighting, and wired audio are the three setup changes with the highest return for the least effort.
- AI scoring on async platforms evaluates answer completeness and STAR structure. Use 80-90% of the allotted time, start with context immediately, and end with a measurable result.
- When tech fails in a live interview, surface the problem immediately and move to recovery. The composure you show in that moment is part of the evaluation.
