What to Wear to an Interview: In Person, on Video and for AI Interviews

The night before an interview, most people ask the same question: what do I wear? It is a fair one. Clothes will not get you the job, but they can quietly undermine your confidence or distract the person across from you. The aim is simple. You want the interviewer to remember what you said, not what you were wearing or what was behind you.

This guide covers three situations: meeting in person, interviewing on a video call, and facing an AI-led interview where software scores your answers.

What to wear to an interview in person

The safest rule is to dress one step above what people wear day to day at that workplace. If staff wear jeans and trainers, wear smart trousers and a clean shirt or blouse. If they wear suits, wear a suit. If you cannot tell, a smart, simple outfit is never a mistake. Check the company's website and social media for photos of the team, or ask the recruiter what the dress code is. Recruiters are usually happy to answer.

Research points the same way. In a 2019 Accountemps survey of more than 2,800 US senior managers, 94% said how a candidate dresses matters, 37% said candidates should always wear a formal suit, and 36% said it depends on the position or department. The firm's own advice is to dress one step above the company's usual level of formality (Robert Half).

A few principles hold in almost every setting:

• Fit beats fashion. A plain outfit that fits well looks better than a trendy one that does not. If you can, try everything on a few days before.
• Choose calm colours. Navy, grey, black, white and soft neutrals are safe. A single accent colour is fine.
• Clean and pressed. Check for creases, loose threads, scuffed shoes and stains. Interviewers notice care.
• Comfort counts. If you are tugging at a collar or limping in new shoes, you will be thinking about that instead of the question. Wear shoes you can walk in.
• Keep grooming simple. Tidy hair and nails, light or no fragrance, and minimal jewellery that does not jingle or distract.
• Plan the practicalities. Bring a clean copy of your CV, a notebook and pen, and a bag or folder that is tidy. Aim to arrive 10 to 15 minutes early, which gives you time to settle.

What to wear to a video interview

Dress as you would for the same interview in person. Many people wear the complete outfit, trousers and shoes included, for two reasons: it puts you in the right frame of mind, and it saves you from an awkward moment if you have to stand up unexpectedly.

Camera changes a few things:

• Pick solid, mid-tone colours. Blues, greens, burgundy and charcoal tend to look good on screen.
• Avoid busy patterns. Fine stripes, checks and herringbone can shimmer or blur on video. Wharton's communication programme likewise warns against tight patterns that pulsate on camera and against matching your background (Wharton).
• Be careful with white and black. Bright white can wash you out, and pure black can lose detail in poor light.
• Do not match your background. A beige jumper against a beige wall makes you look like a floating head.
• Keep accessories quiet. Large earrings, bangles and necklaces can clink against a microphone or catch the light.

What to wear for different types of job

The right outfit depends on the sector, the seniority of the role and the culture of the company. The table below is a starting point, not a rulebook. Always check what the team actually wears.

The same survey found that suits were preferred more often in finance, insurance and real estate (46% of managers) than in construction (28%) or retail (26%) (Robert Half). These are US figures, so treat them as a guide to the pattern rather than exact numbers for the UK.

Interviewing as a tech leader. Senior tech candidates are judged on judgement and credibility, so aim for polished rather than formal. A well-cut blazer or quality knitwear with dark trousers suits most engineering and product leadership interviews. A suit can look out of step in a company where the founders wear T-shirts, but a hoodie can look careless when you are asking to run a team. Look at how the leadership team appears on the company website, in conference talks and on LinkedIn, then dress slightly above it. Opinion is divided: in a Robert Half Technology survey reported by CIO.com, 35% of CIOs said IT professionals should wear a suit to an interview (CIO.com), while HubSpot's recruiting team describes the best tech outfit as usually somewhere between business and everyday wear (HubSpot).

Interviewing at a start-up. Start-ups often care more about energy and fit than dress codes. Smart casual is usually right, and the aim is to look prepared without looking stiff. If you are unsure, wear a jacket you can remove. You can always relax your look on arrival, but you cannot easily dress up. One US tech recruiter suggests going just short of a full suit, and notes that British start-ups tend to be dressier (Betts Recruiting).

When you cannot tell. Ask the recruiter, "Is there a dress code I should follow for the interview?" It is a normal question and shows attention to detail.

Video interview background: how to set up your light, camera and sound

For a remote interview, your setup says as much about you as your outfit. It shows you took the occasion seriously. The good news is that it takes about 15 minutes and almost no money.

This matches the guidance from university career services. Penn, UMass Lowell and Wharton's communication programme all advise a neutral, distraction-free background, good light on your face, a camera at about eye level, and looking at the lens rather than the screen (Penn, UMass Lowell, Wharton).

Background

• Choose a plain, uncluttered wall or a tidy bookshelf. A few neutral items are fine. Remove laundry, open cupboards and anything personal you would not want discussed.
• Avoid virtual backgrounds where you can. They often flicker around hair and shoulders. If your space is untidy and you have no alternative, a gentle blur is a safer choice than a cartoon beach.
• Sit a metre or so in front of the wall, not pressed against it, so you do not cast a harsh shadow.

Camera

• Raise your laptop until the camera is at eye level. A pile of books works well. A camera that looks up your nose or down at your head is distracting.
• Frame your head and shoulders, with a little space above your hair.
• Look at the camera lens when you speak, not at your own face on screen. It is the closest thing to eye contact you can offer.

Light

• Face your light source. A window or a lamp placed behind your screen lights your face evenly.
• Never sit with a window behind you. You will appear as a silhouette.
• If the room is dim, put a desk lamp slightly to one side and angle it at a wall or the ceiling to soften it.

Sound and connection

• Use headphones or earbuds with a built-in microphone if you can. Clear audio matters more than a perfect picture.
• Choose the quietest room available, and tell others in the house when you will be on the call.
• Use a wired connection or sit close to your router. Close other apps, turn off notifications and plug in your laptop.
• Test the link a day before, and join five minutes early on the day. Keep water and a printed copy of your CV within reach.

Do clothes and background matter for an AI interview?

Yes, but not in the way people fear. In an AI video interview you answer set questions on camera, and the platform notes and scores your answers behind the scenes. A human usually reviews the submissions later. According to a February 2026 Wall Street Journal report, executives at AI interview platforms say their systems generally do not score eye contact, facial expressions or attire (WSJ, via Murray Resources). Platforms differ, though. A 2023 report republished by the Anchorage Daily News described one provider that scans video for body language and facial emotion and another that assesses only the transcript (Anchorage Daily News). So read the invitation, or ask the employer, to find out what is assessed.

It still matters, for three practical reasons:

• A person reviews the recording eventually. The WSJ report says a human eventually reviews submissions, so a tidy setting and professional dress still count. Experts quoted there also say dressing smartly can put you in the right frame of mind.
• Audio matters most. One AI interview expert quoted by the WSJ warns that if the system cannot transcribe you accurately, you can score nothing on that question. Use a headset or external microphone and a quiet room.
• Delivery may count. Experts in the same report say platforms can evaluate pacing, confidence and clarity as well as content, and some systems note when a candidate seems to be reading from notes. Practise speaking naturally to the camera.

What deserves most of your preparation is the content:

1. Structure your answers. Describe the situation, what you did, and the result. Check the time limit before you start, as some platforms give you only about 30 to 60 seconds to prepare each answer (Clemson University).
2. Use the language of the job description, where it is true for you. If the role asks for stakeholder management and you have done it, say so in those words.
3. Give specifics. Numbers, names of tools and real outcomes beat general statements.
4. Speak naturally. Reading from a script usually shows in your pace and tone, and experts quoted by the WSJ advise using industry terms naturally rather than stuffing in keywords.
5. Practise on camera. Record yourself answering a few common questions, then watch it back for pace, lighting and eye line.
6. Use your retake if you are offered one, and know the time limit and the number of attempts before you begin.

The night-before checklist

• Outfit chosen, tried on, clean and pressed
• Shoes comfortable and polished (in person), or full outfit on (video)
• Route, travel time and arrival plan checked (in person)
• Camera at eye level, face lit from the front (video or AI)
• Background tidy, phone on silent, notifications off
• Headphones and microphone tested, laptop charged
• Link tested and joining details to hand
• CV, job description and three examples of your best work ready
• Water, and a good night's sleep

People rarely remember a perfect outfit. They remember someone who looked prepared, sounded clear and gave good answers. Get the basics right, then put your energy into what you are going to say.

Frequently asked questions

What should I wear to an interview if I do not know the dress code?

Dress one step above what staff wear day to day, or ask the recruiter what the dress code is. A smart, simple outfit that fits well and is clean and pressed is rarely a mistake.

Do I need to dress fully for a video interview?

Dress as you would for the same interview in person. Many people wear the complete outfit because it puts them in the right frame of mind and avoids an awkward moment if they have to stand up.

Does what I wear matter in an AI interview?

Executives at AI interview platforms told the Wall Street Journal that their systems generally do not score attire. A human usually reviews the recording later, though, so dressing smartly and keeping your setting tidy still helps. Clear audio matters most.

What should a tech leader or start-up candidate wear to an interview?

Aim for polished smart casual, such as a well-cut blazer or quality knitwear with dark trousers. Look at how the leadership team dresses and go slightly above it. If you are unsure, wear a jacket you can remove.
