Interview Prep Basics: How to Prepare for a Job Interview
You tailored your resume, got past the screening software, and landed an interview. Now what? This guide covers everything you need to do before, during, and after a job interview — backed by real hiring data, not guesswork.
TL;DR
- Research the company and re-read the job description before every interview
- Use the STAR method (Situation, Task, Action, Result) for behavioral questions
- Practice answers out loud — thinking through them is not the same as saying them
- Prepare 3-5 questions to ask the interviewer — it shows genuine interest
- Send a thank-you email within 24 hours — most hiring managers say it matters
Why Interview Preparation Actually Matters
Most people know they should prepare for interviews. Most people also don't do it very well. Some hiring surveys suggest that many hiring managers form a strong impression within the first few minutes of an interview. That doesn't mean you need to be perfect — it means you need to come across as prepared and confident, which is almost entirely a function of how much you practiced beforehand.
According to a Glassdoor analysis, the average corporate job opening receives about 250 applications. Of those, roughly 4-6 candidates get invited to interview. You've already beaten significant odds just by getting the interview — preparation is how you close the deal.
The good news: interview preparation is a skill, not a talent. It follows a repeatable process. This guide walks through that process step by step.
Step 1: Research the Company
This sounds obvious, but "research the company" doesn't mean glancing at their homepage. Interviewers can tell the difference between someone who spent five minutes and someone who spent thirty.
Here's what to look at:
- • Their website — specifically the About, Mission, and Values pages. Note any language that resonates with you.
- • Recent news — Google the company name with a date filter for the past 3 months. Did they launch a product? Get funding? Win an award?
- • Their social media — LinkedIn posts from the company and from the hiring manager (if you know who that is) give you a sense of what they care about right now.
- • Employee reviews — Sites like Glassdoor can reveal company culture, common interview questions, and what current employees say about working there.
- • The job description itself — Read it again. This time, underline the top 3 responsibilities and top 3 required skills. These are what your interview answers should center on.
Step 2: Prepare for Common Questions
While every interview is different, certain questions come up again and again. Preparing strong answers for these gives you a foundation you can adapt on the fly.
Questions You Should Always Prepare For
- 1 "Tell me about yourself."
This is not your life story. Give a 60-90 second summary: where you are now, how you got here, and why you're excited about this specific role.
- 2 "Why are you interested in this role?"
Connect something specific about the company or role to your skills and goals. Generic answers like "it seems like a great company" don't land.
- 3 "What are your strengths?"
Pick 2-3 strengths that directly relate to the job description. Back each one with a brief example.
- 4 "What is your greatest weakness?"
Name a real weakness (not "I work too hard") and explain what you've done to address it. Interviewers want self-awareness, not perfection.
- 5 "Tell me about a time you faced a challenge."
This is where the STAR method comes in. We'll cover that next.
- 6 "Why are you leaving your current job?"
Keep it positive. Focus on what you're moving toward, not what you're running from. Never badmouth a former employer.
- 7 "Where do you see yourself in five years?"
Show ambition that aligns with the company's growth. They want to know you'll stay and grow, not leave in six months.
Step 3: Master the STAR Method
Behavioral questions — the "tell me about a time when..." variety — are the most common type of interview question across industries. The STAR method gives you a simple framework for answering them clearly.
Situation
Set the scene. Where were you? What was the context? Keep this brief — 1-2 sentences.
Task
What was your responsibility? What needed to be done? Make your role clear.
Action
What did you actually do? Be specific. Use "I" not "we." This is the longest part of your answer.
Result
What happened? Quantify if possible. What did you learn? How did it help the team or company?
Example STAR Answer
Question: "Tell me about a time you improved a process."
Situation: At my previous job, our team spent about 3 hours every Monday manually compiling a client report from four different spreadsheets.
Task: My manager asked me to find a way to reduce the time spent on this weekly report.
Action: I built a simple dashboard that pulled data from all four sources automatically. I tested it for two weeks alongside the manual process to make sure the numbers matched, then trained the team on how to use it.
Result: The report that used to take 3 hours now takes about 20 minutes. Over a year, that saved roughly 140 hours of team time. My manager rolled it out to two other departments.
Pro tip: Prepare 5-8 STAR stories from your experience before the interview. Choose stories that demonstrate different skills — leadership, problem-solving, teamwork, handling pressure, learning from failure. Most behavioral questions can be answered by adapting one of these prepared stories.
Step 4: Practice Out Loud
This is the step most people skip, and it's arguably the most important one. There's a significant difference between knowing your answer in your head and saying it smoothly out loud.
When you only rehearse mentally, you tend to gloss over transitions and stumble over wording in the actual interview. When you practice out loud — even just to yourself — you catch the rough spots early.
Ways to practice effectively:
- • Record yourself on your phone and play it back. You'll immediately notice filler words, pacing issues, and unclear explanations.
- • Practice with a friend who can give honest feedback. Ask them: "Did that answer make sense? Was it too long?"
- • Use a mirror if you can't find a practice partner. It feels awkward, but watching your body language while speaking is valuable.
- • Time your answers. Most interview answers should be 1-2 minutes. If you're going past 3 minutes, trim the setup and get to the point faster.
Step 5: Prepare Questions to Ask the Interviewer
"Do you have any questions for me?" is not a formality — it's part of the interview. Multiple hiring surveys suggest that interviewers view candidates more negatively when they have no questions about the company or role.
Good questions show you've done your homework and are genuinely evaluating whether this job is right for you. They also help you gather information to make a better decision if you get an offer.
Strong Questions to Ask
- "What does a typical day or week look like in this role?"
- "What are the biggest challenges the team is facing right now?"
- "How would you describe the team culture?"
- "What does success look like in the first 90 days?"
- "What's the growth path for someone in this position?"
Questions to Avoid in a First Interview
- "What does your company do?" — Shows you didn't research
- "How soon can I take vacation?" — Save benefits questions for after an offer
- "Did I get the job?" — Comes across as impatient
- "No, I don't have any questions." — Always have at least one
Step 6: Handle Logistics the Day Before
Small logistical problems — getting lost, joining the wrong video link, wearing something uncomfortable — can rattle your confidence before the interview even starts. Eliminate these the day before.
For In-Person Interviews
- ☐ Map the route and add 15 minutes of buffer time
- ☐ Lay out your outfit the night before
- ☐ Print 3-5 copies of your resume
- ☐ Pack a notepad, pen, and your list of questions
- ☐ Confirm the interviewer's name and title
For Virtual Interviews
- ☐ Test your camera, microphone, and internet connection
- ☐ Check your background and lighting
- ☐ Install and log into the video platform beforehand
- ☐ Have your resume open on screen for reference
- ☐ Close other tabs and silence notifications
Step 7: During the Interview
You've done the preparation. Now it's about execution. Here are the things that matter most during the actual conversation.
- • Arrive 10-15 minutes early (in-person) or 5 minutes early (virtual). Early enough to settle in, not so early that it's awkward.
- • Listen to the full question before answering. It's fine to pause for 2-3 seconds to collect your thoughts. Rushing into an answer often leads to rambling.
- • Be specific, not generic. "I increased sales by 15% in Q3 by implementing a new outreach strategy" beats "I'm a hard worker who always hits my targets."
- • It's okay to say "I don't know." If you get a question you can't answer, say so honestly. You can add: "Here's how I'd approach figuring that out."
- • Take notes. Jotting down key points shows engagement and gives you material for your thank-you email.
Step 8: Follow Up After the Interview
A survey by TopResume found that 68% of hiring managers say a thank-you note influences their hiring decision. Despite this, many candidates skip this step entirely — which means sending one immediately sets you apart.
What makes a good thank-you email:
- • Send it within 24 hours of the interview
- • Reference something specific from the conversation — this proves it's not a template
- • Restate your interest in the role and briefly mention why you're a strong fit
- • Keep it to 3-4 sentences. Brevity is a strength here.
Example Thank-You Email
Subject: Thank you — [Job Title] Interview
Hi [Name],
Thank you for taking the time to speak with me today about the [Job Title] role. I really enjoyed learning about [specific thing discussed — e.g., "the team's approach to customer onboarding"].
Our conversation reinforced my excitement about the opportunity. I believe my experience with [relevant skill] would allow me to contribute to [specific goal or challenge they mentioned] from day one.
Please don't hesitate to reach out if you need any additional information. I look forward to hearing from you.

5 Common Interview Mistakes to Avoid
Vague answers like "I'm a team player" don't convince anyone. Have concrete stories ready.
Even if you had a terrible experience, keep it professional. Interviewers wonder if you'll talk about them the same way.
Keep answers to 1-2 minutes. If the interviewer wants more detail, they'll ask follow-up questions.
The best answers connect your experience to the company's needs. Frame your skills in terms of what you can do for them.
It signals disinterest. Always have at least 3 questions prepared, even if some were answered during the interview.
Frequently Asked Questions
How long should I spend preparing for a job interview?
Most career coaches recommend spending at least 2-4 hours preparing for each interview. This includes researching the company, reviewing the job description, preparing STAR stories, and practicing answers out loud.
What is the STAR method for interviews?
STAR stands for Situation, Task, Action, Result. It's a framework for answering behavioral interview questions by telling a structured story from your experience. You describe the situation you were in, the task you needed to accomplish, the action you took, and the result you achieved.
What should I bring to a job interview?
Bring multiple printed copies of your resume, a notepad and pen, a list of your prepared questions, the interviewer's name and contact information, and a portfolio of relevant work if applicable. For virtual interviews, have your resume open on screen and test your camera and microphone beforehand.
How soon after an interview should I send a thank-you email?
Send your thank-you email within 24 hours of the interview. According to a survey by TopResume, 68% of hiring managers say a thank-you note positively influences their decision. Keep it brief, reference something specific from the conversation, and restate your interest in the role.
What are the most common interview questions?
The most common include: "Tell me about yourself," "Why are you interested in this role," "What are your strengths and weaknesses," "Tell me about a time you faced a challenge," "Why are you leaving your current job," and "Where do you see yourself in five years." Preparing answers for these covers a large portion of what most interviewers ask.
Should I follow up if I haven't heard back after an interview?
Yes. If the interviewer gave you a timeline and it has passed, it's appropriate to send a polite follow-up email. If no timeline was given, waiting about one week after the interview is generally a good time to check in.
