Tech has a reputation for not caring what people wear. That is only half true. Nobody expects a suit. But people still notice whether you look like you took the day seriously.
The goal for an interview or a first day is simple. Look like you already work there, on a day when you have something important to present. Clean, fitted, and quiet. Nothing that pulls attention away from what you are saying.
Here is how to get there for each situation you are likely to face.
The rule that covers most of it
Dress one step above the team's normal. If the engineers wear tees, wear a polo or a collared knit. If they wear polos, add a layer. If you cannot tell, a collared shirt with a clean quarter-zip over it is hard to get wrong.
Keep anything on your chest small. A logo is fine. A slogan is not. You want the interviewer reading your work, not your shirt. Save the tees with words on them for after you have the job.
Fit matters more than price. A polo that sits right at the shoulders looks better than an expensive shirt that is too big. Try everything on a few days before. Do not find out the morning of that a seam pulls when you sit.
The onsite interview
An onsite is long. You may be in four or five rooms, at a whiteboard, at lunch with the team, and walking between buildings. Your clothes need to hold up for all of it.
- Start with a polo that stays neat. The Workday Stretch Polo ($68) is a stretch jersey polo, wrinkle-resistant, with a small embroidered TT on the chest and nothing else. It still looks pressed after a morning of sitting and standing.
- Bring a layer. Conference rooms are cold. The Ellipsis Quarter-Zip ($68) in charcoal goes over a collar and comes off cleanly if the room warms up.
- Dark trousers or chinos. Clean, not distressed. Dark jeans can work at a casual company if they are crisp.
- Simple shoes. Leather sneakers or plain loafers. Make sure you can walk a campus in them.
Whiteboard sessions mean reaching up and turning your back to the room. Wear something that stays tucked or sits cleanly untucked. Test it with your arms raised.
The video interview
On camera, only the top third of you exists. That makes the choice easier, but the details count more.
- Pick solid, medium-to-dark colors. Navy, charcoal, and slate read well on most webcams. Bright white can wash out. Fine stripes and small checks can shimmer on screen.
- Put structure at the collar. A collar frames your face. The MCP Polo ($68) is navy with a tonal monogram, so the chest stays clean on camera.
- Consider a quarter-zip over the polo. The Delve Quarter-Zip ($68) adds a neat line at the neck and keeps you warm if your home office runs cool.
- Check the frame. Turn on your camera ten minutes early. Look at what it sees. Adjust the light before you adjust the shirt.
Dress fully, even below the frame. You may need to stand up to grab a charger or close a door. It also changes how you carry yourself.
The first day
The first day is not an interview, but people form their first impression of you as a colleague. You will meet your manager, your team, and probably someone from IT. You will sit through setup and introductions.
Aim for the same level as your onsite, then relax it slightly over the first two weeks once you see how the team actually dresses. It is easier to dress down later than to recover from looking too casual on day one.
- A clean polo or collared knit, like the Workday Stretch Polo.
- A soft layer you can keep on at your desk. The Wordmark Crewneck ($65) sits over a collar and has only a small embroidered wordmark on the chest.
- If the office is fully casual, a plain heavyweight tee works. The Heavyweight TT Tee ($44) holds its shape and carries only a small TT on the chest.

What to leave at home, for the interview and the first day:
- Shirts with jokes, slogans, or old conference logos.
- Hats, unless you are told the culture is fully casual. Even then, skip it on day one.
- Anything you have never worn before. New clothes should be tested, not debuted.
- Strong cologne. Interview rooms are small.
The point of all this
Nobody gets hired for a polo. But the right clothes take one variable off the table. You stop thinking about how you look. You start thinking about the problem in front of you.
That is the whole job of an interview outfit. Get dressed, check the mirror once, and then forget about it. The work is what they came to see.
