TL;DR: Crushing an interview comes down to three things: dress appropriately for the role, research the company before you walk in, and pitch how you fit and add value with confidence. Nail the basics and you stand out immediately.

Interviews aren’t won with tricks. They’re won with preparation.

I teamed up with Trey Bryant for a skit showing the wrong way and the right way to walk into an interview and the contrast is bigger than most people think. Here’s what actually matters.

What should you wear to a job interview?

Dress for the job you want, not the couch you’re sitting on.

The wrong way: floral button-up over a tank top, jeans, sunglasses indoors. You might think “be yourself” is good advice. It’s not not here. Showing up underdressed tells the interviewer you didn’t think this was worth preparing for.

The right way: a dark suit and tie for formal roles, or clean, polished business attire matched to the company’s culture. When in doubt, overdress slightly. Nobody ever lost an offer for looking too sharp. Plenty of people have lost one for looking like they wandered in off the street.

Why does your entrance matter so much?

Because the first sixty seconds set the tone for everything after.

Walk in with a firm handshake and real eye contact. Not a limp hand, not eyes on the floor a genuine, confident greeting. Greet people by name when you can. Sit like you belong there.

This isn’t about being fake. It’s about showing respect for the opportunity and for the people giving you their time. Interviewers are asking themselves one question the whole time: “Can I picture working with this person every day?” Your entrance answers it before you say a word.

How do you research a company before an interview?

This is where most candidates get lazy and where you can pull ahead fast.

Before the interview, learn the basics: what the company does, who their customers are, what’s in the news about them, and what the role actually requires. Read the job description twice. Skim their recent press or blog posts. Check the interviewer’s LinkedIn.

Then use it. When you can say “I saw your team just launched X, and here’s how my experience maps to that,” you stop being one of thirty applicants and become the one who did the homework. Preparation is a form of respect, and interviewers feel it.

Confidence isn’t a personality trait it’s what preparation looks like from the outside.

How do you pitch yourself in an interview?

Don’t just list your background. Connect it to their problems.

The formula is simple: here’s what I’ve done, here’s what I understand about what you need, and here’s how I add value. Every answer should point back to the same message I can do this job, and I can do it well.

Speak with confidence, not arrogance. There’s a difference between “I crushed every target for three years” (backed by numbers, great) and “I’m obviously the best person for this” (backed by nothing, terrible). Let your results do the flexing.

And bring a resume. Even if they have one. Even if it’s “all online.” Walking in empty-handed because you assumed they’d print it is a small thing that signals a big thing: you didn’t prepare.

What are the biggest interview mistakes to avoid?

From the skit, the hall of shame is clear:

• Treating it casually. “My dawg!” and a hug are for your friends, not your interviewer.

• No eye contact, weak handshake. It reads as disinterest or insecurity neither gets you hired.

• No resume. Always bring copies.

• No research. If you can’t say what the company does, why should they believe you want to work there?

• Making it about you. Complaining about your commute or joking about the process tells them you’re already checked out.

None of these require talent to fix. They require effort. That’s the good news effort is a choice.

Key takeaways

• Dress appropriately when in doubt, go sharper than you think you need to.

• Open with a firm handshake, eye contact, and a genuine greeting.

• Research the company: their work, their news, and your interviewer’s background.

• Pitch how you fit and add value, connecting your experience to their needs.

• Bring printed copies of your resume, even if they already have one.

• Speak with confidence backed by real results, not empty claims.

FAQ

What should I wear to a job interview?

Dress one level above the company’s everyday dress code. For corporate roles, a suit or equivalent professional attire. For startups, polished business casual. Clean, fitted, and intentional always beats casual.

How should I greet an interviewer?

With a firm handshake, direct eye contact, a smile, and their name: “Great to meet you, [Name].” Stand when they enter. Small courtesies signal professionalism before the questions even start.

How much should I research before an interview?

Enough to speak intelligently about what the company does, who it serves, and what’s happening with it lately. Read the job description closely, check recent news, and review your interviewer’s LinkedIn profile. Thirty to sixty minutes of research puts you ahead of most candidates.

What’s the best way to answer “tell me about yourself”?

Give a tight 60-to-90-second arc: where you’ve been, what you’ve accomplished, and why you’re excited about this specific role. End pointed at them how your background maps to what they need.
