From the route you test the day before to the note you send that evening, here is what actually shapes how an interviewer remembers you.
By the end of this guide you will know exactly what to do in the week before an in-person interview, what to do with your hands, voice and questions once you are in the room, and what to send afterwards and when. The first impression is not a personality trait — it is a set of small, repeatable decisions about timing, preparation and attention.
Dress codes, security procedures and interview length vary a lot by employer, industry, state and country, so treat the specifics here as defaults to confirm with whoever invited you.
Before
Preparation is what buys you a calm first ninety seconds. Work backwards from the interview time.
Three to seven days out
- Confirm the logistics in writing. Reply to the invitation and ask for the full street address, the floor or suite, the names and job titles of everyone you will meet, the expected length, and whether there is a test, tour or presentation. Ask what ID or check-in the building requires — many offices, hospitals and industrial sites need photo ID or a pre-registered visitor pass, and the rules differ by employer and by country.
- Pull six requirements out of the job posting and write one example for each. Aim for roughly 90 to 120 seconds spoken per example, with the situation, what you personally did, and a measurable result.
- Spend 45 minutes on the employer: their products or services, who their customers are, and their three most recent public announcements. One sentence of this in the room separates you from candidates who read nothing.
- Write five questions to ask, and keep two in reserve in case the others get answered.
The day before
- Test the journey at the same time of day you will travel, and time it. Add a 30-minute buffer on top of whatever it takes. If you cannot travel it, check the route on a map and look at the building entrance in street view so you recognise it.
- Try the whole outfit on, including shoes. Check for missing buttons, scuffs and creases. As a default, dress one step smarter than the team's everyday clothing — but this swings hard by employer, sector and region, so if you are unsure, ask the recruiter what people wear. For a site visit involving a plant floor or kitchen, ask about closed-toe shoes and whether jewellery needs to come off.
- Pack one folder: four printed copies of your resume, a notepad, two pens, photo ID, your list of references, and anything the posting asked for such as certificates or a portfolio.
- Rehearse out loud, not in your head. Record two answers on your phone and listen once for filler words and pace.
- Look up current pay ranges for the role in your area using live job postings and public pay data before you go, so a salary question does not catch you flat. Whether the employer must publish a range in the posting depends on state and city rules, so check the listing itself.
The morning of
- Eat something and carry water. A 45-minute panel on an empty stomach is a disadvantage you can remove.
- Arrive in the surrounding area 30 minutes early and wait somewhere nearby. Present yourself at reception 5 to 10 minutes before the start time — earlier than that often leaves the receptionist and your interviewer managing you.
- In the last ten minutes: phone fully off and in your bag, not on the table on silent. Check your teeth. Reread the interviewers' names and say them once to yourself.
- Be polite to everyone from the parking attendant onwards. In small offices the person who signs you in is often asked what you were like.
During
These are things an interviewer can see and later describe to a colleague. That is the test of a good first impression.
- Stand up when the interviewer comes to collect you, and bring your folder in one hand so the other is free.
- Offer a handshake if they extend one first. Handshake norms shifted in many workplaces and differ by country and by sector, so follow their lead rather than forcing it. A nod and a clear "Good to meet you, [name]" covers you either way.
- Use each person's name once in the first two minutes and once more when you ask them something later.
- Sit back in the chair rather than perching on the edge, and keep both feet on the floor. Put the folder and notepad on the table, phone and coffee off it.
- Wait a full beat — about two seconds — after the question ends before you start answering. It stops the overlap and makes you sound considered.
- Answer in the order the question was asked, and stop. If you have been talking for more than two minutes, land the point and ask, "Would you like more detail on that part?"
- Put numbers in at least three of your answers: how many accounts, how many hours saved, what the error rate was before and after.
- Take short notes when they describe the role, the team or the next steps. Write down the names of systems, tools or clients they mention and use one of them in a later question.
- In a panel, start your answer facing the person who asked and share eye contact with the others as you go, finishing back with the asker.
- When you do not know something, say so and say what you would do: "I haven't used that system. I learned our current one in about two weeks by shadowing the scheduler, and I'd expect to do the same here."
- Ask your questions at the end, and make at least one about the work itself: what the first 90 days look like, how success is measured at six months, what the last person in the role found hardest.
- Before you leave, ask what the next step is and when you should expect to hear. Write the answer down in front of them.
After
The follow-up is short and fast. It is also where most candidates go quiet and lose ground.
- Within two hours: write down, for yourself, the names and titles you met, the questions that threw you, and anything you promised to send. Memory for this fades the same day.
- Same day, before the end of business: email a thank-you note to each interviewer, or to the recruiter asking them to pass it on if you do not have addresses. Keep it to 100 to 150 words and reference one specific thing from the conversation.
- Within 24 hours: send anything you offered in the room — a work sample, a certificate number, a reference list, a short note on how you would approach the problem they described.
- Same day: tell your referees the interview happened, which role it was, and what the employer is likely to ask them about.
- Two business days after the date they gave you: if you have heard nothing, send one short follow-up to the recruiter restating your interest and asking about timing. One. Then wait another week before a final check-in.
- If you are rejected: reply once, thank them, and ask whether they would consider you for similar openings. Keep the tone the same as it was in the room — internal recruiters remember both the gracious and the sour.
Sample thank-you email — candidate for a shift supervisor role at a distribution centre
Hi Dana,
Thank you for the time this morning, and for walking me through the pick line — seeing the handoff between the night and day shifts made the staffing problem you described much clearer.
The part that stayed with me was your point about missed cut-off times during peak. At my current site I run a crew of 14 on second shift, and we cut late dispatches by rebuilding the pre-shift huddle around the three orders most at risk that day. It took about six weeks to stick, and our on-time rate held through the holiday peak.
I have attached the one-page huddle sheet we use, in case it is useful either way. I am very interested in the role and happy to come back in for the panel stage.
Best, Marcus
Frequently asked questions
What should I wear if the employer has not told me the dress code?
Ask. Email the recruiter and say, "So I'm dressed appropriately, what do people usually wear in the office?" It is a normal question and the answer removes the guesswork. If you get no reply, default to one step smarter than you expect the team to be: clean, pressed, neutral, nothing that needs adjusting while you sit. Norms differ sharply between employers, industries, states and countries, and a site visit to a plant, ward or kitchen may have footwear and jewellery rules of its own.
How early should I actually arrive?
Be in the neighbourhood 30 minutes early and sit somewhere nearby. Walk into reception 5 to 10 minutes before the scheduled time. That window is long enough to clear security and find the floor, and short enough that nobody has to entertain you. If the building needs a visitor badge or a pre-registered pass, ask about it beforehand and add ten minutes. If you are running late despite the buffer, call or email the moment you know, with a realistic new arrival time.
What do I bring with me?
One folder, so you are not juggling items. Inside it: four printed copies of your resume, a notepad and two pens, photo ID, a reference list with permission already obtained, and anything the posting specifically asked for such as certificates, licences or portfolio pieces. Leave coffee outside and keep your phone powered off in your bag. If a presentation is part of the day, bring the file on a drive and email it to yourself as a backup.
Is it still expected that I shake hands?
Follow the interviewer's lead. Practice varies by employer, sector and country, and some workplaces — healthcare and food production in particular — discourage it. Have a clean alternative ready: make eye contact, say "Good to meet you, [name]", and a small nod. Nobody is marked down for not initiating a handshake; people do notice a greeting that is mumbled or delivered to the floor, so put your attention there instead.
