For a tech interview in France, wear neat smart casual. Think well-cut chinos or dark denim, a shirt or fine knit, clean shoes, and a blazer if you like. The suit and tie is no longer the standard. Dress one notch above the team, keep it tidy, and keep it comfortable. Here is how to build the look, adapt it to the company, and reuse it at work afterwards.
TL;DR
- Tech and startup interviews accept neat, relaxed outfits. France Travail says the suit-and-tie standard is no longer the norm in many fields, tech included.
- Check the company website and social media first. Then dress one notch above what the team wears.
- Safe formula: chinos or dark jeans, shirt or fine knit, optional blazer, clean leather shoes or very plain sneakers.
- Skip hoodies, joggers, distressed denim, flashy colors, visible logos and heavy perfume.
- Video interview? Same care as in person. Neutral background, good light, no loud patterns.

Why tech dress codes feel confusing
Tech has a reputation for hoodies and sneakers. Candidates read it as "anything goes". It does not.
The daily dress code of a team and the dress code of an interview are two different things. Employees are comfortable and known. You are new, and the recruiter has only a few minutes of impressions to work with. A neat outfit says you took the meeting seriously, without looking like you are applying to a bank.
In France, this is easier than it used to be. France Travail, the public employment service, states that more relaxed but neat outfits are accepted in many fields, including tech. The key word is neat. Relaxed does not mean careless.
Step 1: Find out what the company wears
Do this before you open your wardrobe. Five minutes of research saves you from the two classic mistakes: overdressing at a casual scale-up, or underdressing at a tech firm that serves banks and insurers.
France Travail suggests checking the company's website or social media to adjust your outfit. Here is where to look:
- Careers page and team photos. Do people wear shirts, knits, tees?
- LinkedIn posts and company events. Meetups and offsites show the real culture.
- Instagram or short videos. Startups love showing their office life.
- The recruiter. Ask what the dress code is. It is a normal question, and it shows attention to detail.
Then apply the dress code +1 rule: dress one notch above what employees wear day to day. If the team wears tees and sneakers, you wear a shirt and clean chinos. If the team wears shirts, add a blazer. We cover the method sector by sector in our guide Dress Code +1: Build Interview Outfits by Sector.
Step 2: Choose your formula
Three sectors, three levels. Pick the one closest to your target company.
| Company type | Typical team look | Your interview outfit |
|---|---|---|
| Early-stage startup | Tees, hoodies, sneakers | Dark jeans or chinos, plain shirt or fine knit, clean minimal shoes |
| Scale-up or product company | Casual shirts, knits, chinos | Chinos, shirt, unstructured blazer, loafers or ankle boots |
| Tech consulting, fintech, B2B software | Business casual to formal | Tailored trousers or skirt, shirt, blazer, leather shoes |
Not sure? Go one level up. Taking a blazer off is easy. Adding one is impossible.
The startup formula
For a startup or tech interview, the suggested look is business casual, such as chinos with a blazer, or a dress with a cardigan. An overly strict suit can feel out of place. That is the advice of a French career blog, and it matches what recruiters tell candidates.
A concrete version:
- Well-cut chinos in navy, beige or charcoal
- Plain shirt in white, light blue or a muted tone, or a fine merino knit
- Optional unstructured blazer
- Leather shoes, loafers, or boots in good shape
The staffing firm Flextelecom proposes a well-cut trouser, either chino or raw denim, with a shirt or an elegant polo. The jacket is optional, and sober, clean sneakers can work. Keep that last point in mind: it is a "can", not a "should".
Dresses and skirts
Yes, you can wear a dress to an interview. A fluid dress is a fine option. Flextelecom also lists a smart trouser, a fluid dress or a skirt with an elegant top, with minimal sneakers, loafers or ankle boots instead of classic shoes. Add a cardigan or blazer and you have a tech-ready look.
The checks are simple:
- Can you sit, walk and gesture comfortably?
- Is the length appropriate for a long conversation, possibly in a low chair?
- Does the fabric hold its shape after a commute?
Shoes
Shoes are where tech candidates take the most risk. Hays France advises against overly casual shoes such as flip-flops or sneakers in interviews, whatever the sector's casual culture. Flextelecom is more flexible and accepts sober, clean sneakers. Our reading: leather shoes, loafers or boots are the safe choice. If the culture is clearly casual and you choose sneakers, take plain, all-white or all-dark, spotless pairs. Our guide to sneaker-friendly office outfits shows which pairs pass at work.
What to avoid
The same recruiter sources agree on a short list of things to leave at home.
- Distressed denim, hoodies and joggers. Hays France puts these on its list, even for casual sectors.
- Oversized tees and sportswear. Flextelecom also flags tracksuits and overly sporty outfits, as well as flashy colors and visible logos.
- Extravagant accessories. Keep jewelry and watches discreet. Anything that jingles or catches the eye pulls attention away from you.
- Strong perfume. Both Hays and Flextelecom advise against overdoing it. Think light, or none. You may be in a small meeting room for an hour.
- Company swag. A hoodie from another startup is a bad idea. Same for a conference tee.
A small aside on the law. In France, an employer can impose a dress code at work only if the nature of the job justifies it and it is proportionate, for reasons such as hygiene, safety or commercial image, under Article L1121-1 of the Labor Code. That concerns the job itself. For an interview, there is no rulebook: the recruiter's impression is what counts.
Video interviews and technical screens
Many tech processes start on a screen. Take it as seriously as the on-site round.
France Travail's advice: dress with the same professionalism and attention to detail as for an in-person interview, with a neutral background and good lighting. Avoid bright colors or complex patterns that could interfere with how the camera renders you.
Practical checklist:
- Dress fully. Not only the top half. You may stand up to fetch something, and the confidence carries.
- Pick solid, mid-tone colors. Navy, grey, dusty green, soft blue. Skip fine stripes and tiny checks.
- Face the light. A window in front of you beats a lamp behind you.
- Clean the background. A plain wall or a tidy shelf.
- Test the full look on camera the day before. Open your webcam. Check the color, the collar, the glare of your glasses.
For live coding rounds, wear something you can type in comfortably. Sleeves that ride up or a stiff jacket will distract you.
Build the look in 10 minutes
Planning the night before beats panic at 7 a.m. Here is a simple routine.
- Pick the target level from the table above.
- Choose one anchor piece. The trousers, the dress, or the blazer.
- Add a shirt or knit in a color that suits your skin tone and photographs well.
- Choose shoes, then clean them.
- Add one accessory at most. A watch, a pair of small earrings.
- Try the whole outfit on. Sit, walk, raise your arms.
- Lay it out. Iron, steam, brush. Done.
If you struggle with the mix, our Smart Casual Outfit Combinations page offers 15 ready looks you can adapt, and the Business Casual Wardrobe Essentials guide lists the core pieces.
Let your AI stylist do the testing
Interview week is stressful. Outfit decisions should not be.
MyTenue is your AI stylist app, on iOS and Android. Here is how it helps for an interview:

- Virtual try-on. Try the look on your personal avatar before you commit.
- Flat-lay images. See the outfit laid out like an editorial shot.
- Weather-adapted suggestions. Rain on interview day? Sorted.
- Calendar planning. Put the outfit on the interview date. Done.
The app has a free version, and paid plans at €5.99 per month (Basic), €9.99 per month (Premium) and €16.99 per month (Gold). See the plans and download the app.
No time to explore now? Start with the free version, scan five pieces, and let the AI propose your first interview look. You can also visit mytenue.com for an overview.
Our perspective: dress for the role, not for a costume
We see the same pattern again and again. People buy a new outfit for the interview, wear it once, and feel strange in it. The result is stiff body language and a lost afternoon of shopping.
Our view at MyTenue is simpler. Your best interview outfit is probably already in your wardrobe. It just needs to be found, combined and checked. A well-cut blazer, one pair of good trousers, a clean shirt and decent shoes cover most tech interviews. If one piece is missing, buy that one piece, and make sure it works with at least three other things you own.
That is also why we built the app around your own wardrobe. Mixing what you have with a few new items keeps your spending down and cuts waste. It also means you feel like yourself on the day, which recruiters notice.
Three rules we repeat to every user:
- Comfort first. If you keep adjusting it, it is wrong.
- One notch above. Not three.
- Rehearse the outfit. Try it on, sit down, look at it on screen.

Make the outfit work after the offer
Good news: a smart casual interview outfit is also a work outfit. Plan it that way and you spend less.
Vogue's advice for converting interview pieces into everyday looks: mix formal items such as a well-cut blazer, a pencil skirt or loafers with basics, or with items that express your own style. A blazer with a plain tee and sneakers on a Tuesday. The same blazer with a shirt for a client demo.
Back to the office, hybrid style
More teams now split the week between home and office. For the days on site, Vogue France suggests a capsule wardrobe of comfortable, versatile, elegant pieces. One example from the magazine: barrel-cut wool-blend trousers with a turtleneck, a blazer and loafers, practical and polished.
This is the same logic as your interview outfit. A small set of pieces that combine in many ways. Our guides help you go further:
- A 15+ outfit plan for a professional capsule wardrobe
- An 8 to 10 piece telework capsule for the days at home
- Five office outfit formulas and a weekly plan
- A workweek outfit planning checklist
Night-before checklist
- Dress code checked on the website, social media or with the recruiter
- Outfit tried on, seated and standing
- Clothes ironed or steamed, no loose threads
- Shoes cleaned
- Accessories reduced to one or two
- Light fragrance, or none
- Video setup tested, if remote
- Backup shirt ready
Keep that list on your phone. It takes two minutes and removes most of the stress. For more on planning around a busy calendar, see Occasion-Ready Outfits With Less Effort.
FAQ
Can I wear jeans to a tech interview?
Often yes, if they are dark, clean and well-cut. Raw or dark denim is accepted by some recruiters, while distressed or faded jeans are on the avoid list of firms like Hays France. When in doubt, choose chinos.
Do I need a suit for a startup interview?
Usually not. An overly strict suit can look out of place at a startup. Chinos with a blazer, or a dress with a cardigan, hits the right note. For tech consulting or fintech, a tailored blazer is safer.
Can I wear sneakers?
It depends on the company. Hays France advises against sneakers in interviews, while Flextelecom accepts sober, clean ones. If the company culture is clearly casual, choose plain minimal pairs. Otherwise, wear loafers, boots or leather shoes.
What should I wear for a video interview?
Dress as you would in person. France Travail recommends a neutral background, good lighting, and no bright colors or complex patterns that can disturb the camera image. Wear full outfit, trousers included, and test it on camera the day before.
How do I know what the company expects?
Check the careers page, team photos and social media accounts. You can also ask the recruiter directly. Then apply the dress code +1 rule: one notch above what the team wears.
