TL;DR
Interview preparation comes down to three things: know the company (research their products, culture, recent news),know your stories (prepare 5-8 examples using the STAR method), and practice out loud (your first time saying answers shouldn't be in the real interview). This guide covers everything from initial research to the follow-up email.
Why Preparation Actually Matters
Here's the uncomfortable truth: the most qualified candidate doesn't always get the job. The most prepared candidate does.
You've probably been there. You knew you could do the job. You had all the right experience. But when they asked "Tell me about a time when..." your mind went blank. Or you rambled for three minutes without making a point. Or you couldn't remember a single question to ask them.
That's not a you problem. That's a preparation problem.
The good news: interview skills are learnable. The people who seem "naturally good" at interviews? They've just practiced more. They've thought through their stories. They've done the research.
This guide gives you a system. Follow it, and you'll walk into interviews feeling like you belong there. Because you will.
Research: Know Who You're Talking To
Before you prepare a single answer, you need to understand who you're talking to. Generic preparation leads to generic answers. Specific preparation leads to "wow, they really get us."
Company Research Checklist
Time Investment
Spend 30-60 minutes on this. It pays off.
The basics (5 minutes)
What does the company actually do? How do they make money? How big are they (stage, headcount, funding)? Who are their customers?
Go deeper (15-20 minutes)
What's their mission or values? What have they announced recently? What are people saying about working there? Who are their competitors? What challenges might they be facing?
Know your interviewers (10-15 minutes)
Look them up on LinkedIn. What's their background? How long have they been there? Have they written anything or been quoted anywhere? Any shared connections or experiences?
Analyze the Job Description
The job description is basically a cheat sheet for what they're going to ask you. Read it like it's the answer key.
- Highlight requirements: What skills and experiences do they mention most?
- Note the language: Mirror their terminology in your answers
- Spot the priorities: What's listed first? What's mentioned multiple times?
- Find the gaps: Where might you need to address concerns proactively?
For each key requirement, prepare a specific example that proves you can do it. "Strong communication skills" → Story about presenting to executives. "Experience with cross-functional teams" → Story about launching a project with engineering, design, and marketing.
Common Interview Questions
You can't predict every question. But you can prepare for the most common ones so well that you're never caught completely off guard.
The classics (prepare for all of these)
Tell me about yourself:
Your 2-minute career narrative. Not your life story.
Why are you interested in this role?:
Connect your goals to what they need.
Why are you leaving your current job?:
Stay positive. Focus on what you're moving toward.
What's your greatest strength?:
Pick one relevant to the role. Give an example.
What's your greatest weakness?:
Be genuine. Show self-awareness and growth.
Where do you see yourself in 5 years?:
Show ambition that aligns with this path.
Behavioral questions
These start with "Tell me about a time when..." and require specific examples from your past. They're looking for evidence of how you actually behave, not how you think you'd behave.

Technical questions
If you're in a technical role, expect questions that test your domain knowledge. These vary widely by field-coding challenges for engineers, case studies for consultants, portfolio reviews for designers.
Preparing Your Stories
Most interview questions are really asking one thing: "Can you show me evidence that you can do this job?"
The best evidence is stories. Specific, concrete examples from your experience that demonstrate the skills they're looking for.
The STAR Method
STAR gives your stories structure. Without it, you'll ramble. With it, you'll be concise and compelling.
S - Situation
Set the scene in 1-2 sentences. Give just enough context to understand the challenge.
T - Task
What was your specific responsibility? What were you trying to achieve?
A - Action
What did YOU do? This should be the longest part. Be specific. Use "I" not "we."
R - Result
What happened? Quantify if possible. What did you learn?
Build your story bank
You don't need a different story for every possible question. You need 5-8 strong stories that can be adapted to different questions.
Story Themes to Cover
- A time you led something (project, team, initiative)
- A time you solved a difficult problem
- A time you worked with a difficult person
- A time you failed and learned from it
- A time you went above and beyond
- A time you had to make a decision with incomplete information
- A time you influenced someone without authority
- Your proudest professional achievement
Write these out. Then practice saying them out loud until they feel natural-not memorized. The reason MORT's Interview Practice works is that it reads your CV and asks questions about your actual experience-so you're practicing with relevant stories, not generic examples.
Questions to Ask Your Interviewer
"Do you have any questions for me?"
The worst answer: "No, I think you covered everything."
This is your chance to learn if you actually want the job, and to show that you're thinking seriously about the role-not just trying to get any offer.

Different Interview Types
The format changes, but the fundamentals don't. Here's what to know about each type.
Phone screens
Usually 20-30 minutes with a recruiter. They're checking basic fit-do you meet the requirements? Are you genuinely interested? Can you communicate clearly?
- Find a quiet place with good reception
- Have your resume and the job description in front of you
- Stand up or walk around-it helps your energy
- Smile. People can hear it in your voice.
Video interviews
- Test your tech beforehand (camera, mic, internet)
- Good lighting matters-face a window or lamp
- Clean up what's visible behind you
- Look at the camera, not the screen, when speaking
- Have notes nearby, but don't read from them
In-person interviews
- Arrive 10-15 minutes early (not more)
- Be nice to everyone-receptionists notice
- Bring copies of your resume
- Firm handshake, eye contact, real smile
Panel interviews
- Make eye contact with everyone, not just the person who asked
- Address the questioner first, then include others
- Note everyone's names and roles at the start
The Day Before
Your preparation should be done by now. The day before is about logistics and mindset.
Logistics checklist
Confirm details
Verify time, location, and who you're meeting with
Plan your route
Or test your video link if it's remote
Lay out your outfit
Prepare what you'll wear the night before
Prepare your bag
Copies of resume, notebook, pen, water
Charge your devices
Phone, laptop, any tech you might need
Mental prep
Night Before Tips
- Review your stories one more time (don't cram new material)
- Review your questions to ask
- Visualize the interview going well
- Go to bed at a reasonable hour
The goal isn't to be perfect. It's to walk in feeling like you've done everything you can. That confidence is real, and interviewers notice it.
During the Interview
First impressions
The first 30 seconds matter more than they should. Walk in with energy. Make eye contact. Smile like you're meeting someone you're genuinely interested in. (Because you should be.)
Answering questions
- Listen fully before you start answering
- Pause briefly to collect your thoughts-it's not awkward
- Keep answers to 1-2 minutes unless they ask for more
- Use specific examples, not hypotheticals
- Check in: "Does that answer your question?"
When you don't know the answer
It happens. Don't panic. Don't make something up.
- "That's a great question. Let me think about that for a moment."
- "I haven't encountered that specific situation, but here's how I'd approach it..."
- "I don't have direct experience with that, but here's something similar..."
Managing nerves
Nervousness is normal. It means you care. A few things that help:
- Deep breaths before you walk in
- Remember: they want you to succeed. They're hoping you're the one.
- Focus on the conversation, not on performing
- If you need a moment, take a sip of water
The Follow-Up
Send a thank-you email within 24 hours. This isn't optional.
What to include
- Thank them for their time
- Reference something specific from your conversation
- Reiterate your interest and why you're a good fit
- Keep it brief (3-4 sentences)
Example
Thank-You Email Template:
Subject: Thank you - [Role] interview
Hi [Name],

Our conversation reinforced my excitement about this opportunity. I'm confident my experience with [relevant skill] would help me contribute to [goal they mentioned].
Please let me know if there's any additional information I can provide. Looking forward to hearing from you.

How to Practice
Reading about interviews doesn't make you better at them. Practice does.
The problem is, practicing alone is hard. You can't hear yourself rambling. You can't tell when your answer is too vague. You can't simulate the pressure of someone actually asking follow-up questions.
Options for practice
- With a friend: Ask someone to run through questions with you. Give them permission to be critical. (The challenge: coordinating schedules, and most friends are too nice.)
- Record yourself: Answer questions on video. Watch it back. Painful but useful for spotting filler words and rambling.
- Mirror practice: Talk through your answers while watching yourself. Better than nothing, but no feedback.
- AI mock interviews: This is what MORT's Interview Practice does-an AI interviewer that asks follow-up questions based on your actual answers, then scores your responses and tells you what to improve. Available whenever you need it, as many times as you need.
The key is saying your answers out loud. Thinking through an answer in your head is not the same as articulating it clearly under pressure. The first time you say an answer shouldn't be in the real interview.
When to practice
Ideally, start practicing 1-2 weeks before your interview. But even one practice session the day before is better than none. MORT users typically do 2-3 mock interviews per company, focusing on different interview types (behavioral, technical, etc.).
Practice with AI. Nail the real thing.
MORT's AI Interview Practice gives you realistic mock interviews tailored to your target role. Real-time follow-up questions. Instant feedback. Available whenever you need it.
