What Should You Wear to a Job Interview?
Dress one notch above the team's daily attire. When in doubt, ask the recruiter.
Definition
Interview attire is whatever signals "I take this seriously and I would fit in here". The reliable rule is to dress one notch above what the team wears day-to-day: a button-down for a t-shirt office, a blazer for a button-down office, a full suit for client-facing roles in finance, law, or consulting.
Why It Matters in Interviews
Harvard Business Review research shows that what you wear measurably affects how others perceive your competence — and how you perform yourself. Underdressing reads as not caring; overdressing in a casual office reads as not researching. Both are avoidable.
How to Use It
Look at recent team photos on the company's LinkedIn or careers page. If unclear, ask the recruiter directly: "What is the dress code for the on-site?" — they always answer. For virtual interviews, dress fully (top and bottom); standing up on camera in shorts has cost real offers.

Quick Tips
- Solid colors, no busy patterns — they distract on video.
- Iron the shirt — wrinkles read more than the cut.
- Comfortable shoes for on-sites; you may walk between buildings.
- Avoid strong cologne or perfume — it travels in small rooms.
FAQ
Is it ever wrong to wear a suit?
In a stereotypically casual tech office, a full suit can read as out of touch. Blazer plus button-down is the safer over-dress.
What about visible tattoos or piercings?
In most modern offices, fine. In conservative industries (law, finance, traditional consulting) consider covering for the first interview, then revealing once you have the offer.
