What to Wear to a Job Interview: Complete Guide

Remote and hybrid work have normalised casual dress for day-to-day working life, and that shift has led plenty of candidates to assume the interview itself has become just as relaxed. It hasn't — at least not to the same degree. An interview is a one-off, high-stakes conversation, and what you wear to it is one of the cheapest, lowest-effort signals you can send about how seriously you're taking the opportunity. It costs nothing extra beyond a bit of forethought, yet it's one of the first things an interviewer registers before you've said a word.

Most structured interview processes — including assessment centres and formal panel rounds — don't include a formal "dress" score on the evaluation rubric. That doesn't mean it's ignored. Interviewers are human, and a candidate who looks put-together and appropriately dressed creates a small, immediate halo effect that colours how the rest of the conversation is received. Conversely, attire that looks careless, or badly mismatched to the room, can create a moment of friction the interviewer has to consciously look past. Preparation on this front lets you walk in and never have to think about it again — your full attention goes to the actual questions, including things like the STAR interview technique for structuring your answers.

Most employers' interview attire expectations fall into one of four broad tiers. Knowing which one applies before you plan your outfit removes almost all of the guesswork.

• Business Professional: A full matching suit (jacket and trousers or skirt), dress shirt or blouse, tie optional-to-expected depending on role and region, polished formal shoes. The most conservative and safest tier for formal, client-facing, or highly traditional employers.
• Business Casual: Smart tailored trousers or a skirt, a collared shirt or blouse, a blazer is optional rather than required, and no tie is expected. Smart shoes, not trainers. This is the default tier for most corporate graduate interviews.
• Smart Casual: A step down again — chinos or dark, well-fitted jeans paired with a smart top, knitwear, or a casual blazer. Trainers are acceptable if they're clean and plain rather than heavily branded.
• Casual: Genuinely relaxed, everyday clothing — still neat and clean, but with no expectation of tailoring or formality. Rare as an actual interview-day expectation, even at employers where it's the daily norm.

To work out which tier applies to a specific interview, start with the company's careers page and any photos of staff or the office — these are usually a reliable, current indicator of daily norms. If it's genuinely unclear, it's entirely appropriate to ask the recruiter directly: "Is there a dress code for the interview?" Recruiters expect this question and would rather you ask than guess. If you can't get a clear answer in time, default to business casual — it's rarely wrong and is easy to adjust up or down with a blazer.

Business professional is still the expected standard for investment banking, corporate law, client-facing consulting roles at the Big Four, and most in-person assessment centres run by large corporate graduate schemes. Employers such as Goldman Sachs — see our Goldman Sachs recruitment guide — and firms running formal assessment days like the one covered in our PwC assessment centre guide are good examples of where this tier is the safe, expected default rather than an option.

Suit

A well-fitted, single-breasted suit in navy, charcoal grey, or black is the safest choice. Fit matters more than price — a moderately priced suit that's been tailored to fit properly will always look sharper than an expensive one that's too loose or too tight through the shoulders and waist.

Shirt or blouse

A plain, well-ironed white or pale blue shirt or blouse is the standard. Avoid busy patterns, logos, or anything overly casual in fabric.

Tie, shoes and grooming

A tie is still broadly expected for men in investment banking and law-adjacent interviews, though conventions vary by firm and region — check if unsure. Shoes should be polished, formal, and free of visible wear. Keep accessories minimal — a watch and simple jewellery are fine, but anything that draws attention away from the conversation is best left at home. Grooming should be neat and understated: this is not the setting to debut a dramatic new look.

This is the default tier for the majority of corporate graduate interviews — retail head office roles, FMCG graduate schemes, and engineering or industrial graduate programmes most commonly expect business casual rather than a full suit. It signals professionalism without over-formality.

A typical business casual combination is tailored trousers or a smart skirt, paired with a collared shirt or a smart blouse. A blazer is a good option to have on hand — it can be added for extra polish or removed if the room turns out to be more relaxed than expected — but it is not strictly required. No tie is needed at this tier. Shoes should be smart — loafers, low heels, or clean leather shoes — rather than trainers or sandals.

If you're unsure whether a specific employer sits closer to business casual or business professional, it's worth reviewing how the role is described alongside your graduate CV and the tone of the job listing — more traditional, hierarchical organisations tend to skew more formal even at business casual companies. When in doubt, arriving slightly more formal than strictly necessary is a safer error than arriving underdressed, and it's a much smaller misstep than showing up in something more suited to a full assessment centre day full of group exercises when the actual expectation was far more relaxed.

Tech companies, startups, and creative industries are often the most genuinely casual workplaces day-to-day — jeans, hoodies, and trainers are frequently the daily norm even for senior staff. That doesn't mean the interview itself should match that exactly. Smart casual is the safe floor for an interview at even the most relaxed employer: it shows you've made an effort for the occasion without looking like you've misjudged the culture entirely.

It's also worth knowing that turning up in a full formal suit to an interview at a casual startup can occasionally read as a signal that you haven't researched the company's culture — interviewers may quietly wonder whether you'll be comfortable in the day-to-day environment. In practice, though, this is rarely actually penalised; most interviewers understand that candidates default to formal wear out of caution, and it's a far smaller issue than being underdressed. If in doubt, smart casual — a blazer over a smart top with tailored trousers or dark jeans — strikes the right balance for almost any tech or startup interview, whether it's a first conversation or a deeper technical round that might draw on skills like the STAR technique for behavioural questions.

Video interviews — including asynchronous, pre-recorded formats like HireVue — carry all the same dress code expectations as an in-person interview for the same role, plus a handful of camera-specific considerations that catch a lot of candidates out.

Two other colour choices to avoid: all-white and all-black. An all-white top can overexpose against most webcam auto-exposure settings, washing out your face; all-black can blend into a dark or poorly lit background and make you look like a floating head with no definition. Mid-tone blues, greys, and muted colours tend to work best on camera across different lighting setups.

It's also worth dressing fully, not just from the waist up. Some video interview formats — particularly live, interactive video interviews rather than pre-recorded ones — occasionally ask candidates to stand, gesture at something, or simply shift position, and being caught in pyjama bottoms is an unnecessary risk. Beyond clothing, treat your lighting and background as part of the overall impression: face a light source rather than sitting with it behind you, and make sure the visible background is tidy and free of clutter. Our dedicated guides on video interview tips and how different platforms compare in our video interview platforms guide cover the technical setup side in more depth.

Use this table as a fast starting point, then confirm against the company's own careers page or by asking the recruiter directly where the expectation is unclear. The same principles apply whether you're preparing for a first-round screen or a second-round interview later in the process — dress code rarely changes between rounds at the same employer.

• Overdressing to the point it feels performative: Turning up in full formal wear to a genuinely casual workplace can occasionally read as a lack of research into the company culture, even though it's rarely actually penalised outright.
• Wearing new shoes or clothing untested: Breaking in new shoes for the first time on interview day risks blisters and visible discomfort. Wear everything at least once beforehand.
• Strong fragrance or cologne: A scent that's noticeable from across a small interview room — or worse, a panel table — can be distracting rather than impressive. Keep it minimal or skip it entirely.
• Wrinkled or ill-fitting clothing pulled out last-minute: Lay out and check your outfit the night before, not the morning of, so there's time to iron, steam, or swap something that doesn't fit right.
• Forgetting video-interview camera framing: For any video round, including HireVue-style formats, check what's visible in frame before you start — half a shirt collar and a messy bookshelf behind you undermines an otherwise polished outfit.
• Ignoring grooming and basic presentation: Clean, tidy hair and neat nails matter as much as the clothes themselves — interviewers register the whole picture, not just the outfit.
