Most people do mock interviews wrong. They run through questions casually with a friend, hear mostly positive feedback, and walk into the real interview no more prepared than before. Here is how to run a mock interview that gives you honest, useful preparation.
Use Someone Who Will Not Go Easy on You
The biggest mistake in mock interviews is choosing someone who feels bad giving hard feedback. Find a friend from a different field, a mentor, or even record yourself and watch it back. The goal is honest simulation, not reassurance. If you need to, hire a coach for one session.
Simulate the Real Conditions as Closely as Possible
Dress the way you would for the real interview. Sit in the same physical setup, video camera at eye level if it is virtual, formal clothes even at home. The psychological preparation of being in the right state matters. Casual practice creates casual habits. For more on this, see our guide on video interview tips that will actually make you stand out.
Use a Question Bank, Not Improvised Questions
Prepare a list of 20 to 30 real interview questions from the role you are interviewing for. Mix behavioral questions, technical questions, and situational ones. Your mock interviewer should ask from the list randomly, not let you know what is coming.
Record Every Mock Interview and Review It
Watching yourself on video is uncomfortable and that discomfort is exactly why it works. You will immediately notice the filler words, the vague answers, the moments where your energy dropped. One viewing of a recorded mock interview teaches you more than ten practice rounds without recording.
Debrief Specifically After Each Session
After each mock, spend 15 minutes on a specific debrief. What were the two strongest answers? What were the two weakest? What would you change? Write it down. The debrief is where the learning actually happens, not in the session itself. For more on this, see our guide on virtual interview tips.

Frequently Asked Questions
What is the STAR method?
STAR stands for Situation, Task, Action, Result. It is a framework for answering behavioral interview questions by providing context, your role, what you did, and the outcome.
How long should a STAR answer be?
Two to three minutes. Situation and Task together should take 30-45 seconds. Spend the most time on the Actions and always end with a concrete Result.
What are common behavioral interview questions?
Common ones include: “Tell me about a time you handled conflict,” “Describe managing competing priorities,” and “Give an example of when you failed and what you learned.”
Should I memorize STAR answers word-for-word?
No. Memorized answers sound robotic. Know your 6-8 strongest stories well enough to tell them naturally. Practice key points, not exact wording.
Preparation is the one variable in an interview that you can control completely. The questions a recruiter asks are largely predictable because interviews are structured around a short list of competencies: communication, problem-solving, collaboration, leadership, and adaptability. When you map your experience to those competencies before you walk in the door, you stop improvising answers and start delivering evidence.
After debriefing hundreds of interviews over my career, the single biggest differentiator between candidates who get offers and candidates who do not is specificity. Vague answers about being a “team player” or a “fast learner” signal that you have not reflected on your own experience. Specific answers with real numbers, real timelines, and real outcomes signal that you know exactly what you have accomplished and can do it again.
Research is the second pillar of interview preparation. Most candidates look up the company’s homepage and stop there. Strong candidates go deeper: they read recent earnings calls if the company is public, review Glassdoor comments from employees in similar roles, and follow the company’s LinkedIn for news from the past three months. Specific, well-researched questions at the end of the interview signal genuine interest and leave a lasting impression. For more on this, see our guide on interview body language.

Anonymous and approximate. We store one number for this article and nothing about you.
Email digest
We also run a layoff tracker, built from company filings and official notices. A plain email summary of what changed on these trackers: the period’s headline numbers and the largest new entries, with links back to the source pages. No images, no tracking pixels. You confirm your address by clicking a link we email you, and every email carries a one-click unsubscribe. Details in the privacy note below.
Privacy note: what we store and how to erase it
What we store: your email address, the choices above, and timestamps (signed up, confirmed, last sent). Nothing else about you. There is no open tracking and no tracking pixel, so we cannot tell whether you opened an email.
About the links: links in the digest pass through a counter on this site that adds 1 to a total for that link and sends you straight on. It records no identifier, no IP address and no browser details, so it counts how many times a link was followed and can never say who followed it.
What it is used for: sending you exactly the emails you ticked, nothing else. The address is never shared, sold, or used for any other purpose.
How to erase it: click the unsubscribe link in any email. That stops all sending immediately, and unsubscribed addresses, along with signups that were never confirmed, are hard-deleted automatically after 30 days. You can also ask via the contact page.
