What Is a Mock Interview?
A mock interview is a practice run of a real job interview. Someone asks you actual interview questions, you answer under pressure, and you get honest feedback on what worked and what didn't — before it counts.
Most candidates skip this. They read every guide, memorize the STAR method, and walk in thinking they're prepared. Then the interviewer says "Tell me about a time you failed" and their mind goes blank.
Knowing the answer and delivering it under pressure are completely different skills. A mock interview is where you build the second one.
How Does a Mock Interview Work?
A mock interview has four steps: setup, the interview itself, feedback, and iteration. The whole thing takes 30-60 minutes. Here's the breakdown:
- Setup — You choose the type of interview (behavioral, technical, case study) and optionally share the job description
- The interview — Someone asks you real interview questions and you respond as if it were the actual interview
- Feedback — You receive specific feedback on your answers, body language, pacing, and areas to improve
- Iteration — You practice again, incorporating the feedback
What Are the Different Types of Mock Interviews?
With a Friend or Peer
Free. Easy to set up. Also the least useful option.
Friends go easy on you. They don't know what "Tell me about a time you showed leadership" is actually testing. They'll say "that was good!" when a real interviewer would probe for specifics you didn't provide.
Use this for: Getting comfortable talking out loud. Not much else.
With a Career Coach
The gold standard for personalized feedback — if you can afford it. Sessions run $100-300 each, and you'll need 3-5 to see real improvement. That's $500-1,500 before your first interview.
Use this for: High-stakes interviews (senior roles, career pivots) where the ROI justifies the cost.
With AI-Powered Tools
AI mock interview tools like Revarta sit in the middle: they ask realistic follow-up questions based on your answers, give you detailed feedback on content and structure, and you can practice at 2 AM in your pajamas.
What makes AI practice different from asking ChatGPT:
- Purpose-built for interviews, not general conversation
- Asks follow-ups that probe weak spots in your answer
- Feedback calibrated against what hiring managers actually evaluate
- No scheduling, no cost per session, no one going easy on you
Who Should Do Mock Interviews?
Everyone who's interviewing. But especially:
- First-time job seekers — you don't know what you don't know yet
- Career changers — explaining a pivot takes practice; your first attempt will be twice as long as it should be
- People with interview anxiety — the only cure for interview nerves is doing more interviews
- Senior professionals — behavioral questions at the leadership level are harder, not easier
- Anyone who hasn't interviewed in 2+ years — interview norms change, and you're rustier than you think
Stop Guessing. See Exactly How You Sound.
Reading about interviews won't help you. Speaking out loud will.

What Questions Are Asked in a Mock Interview?
Mock interviews typically cover the same questions you'd face in a real interview:
- Behavioral questions: "Tell me about a time you overcame a challenge," "Describe a conflict with a coworker"
- Common questions: "Tell me about yourself," "Why do you want this job?" "What's your greatest weakness?"
- Role-specific questions: Technical questions, case studies, or situational scenarios relevant to your field

How to Get the Most from a Mock Interview
Before the Mock Interview
- Share the job description so questions can be tailored to the role
- Treat it like the real thing — dress professionally if it helps you get in the right mindset
- Prepare your stories using the STAR method (Situation, Task, Action, Result)
During the Mock Interview
- Don't pause to restart — push through mistakes like you would in a real interview
- Time your answers — aim for 60-90 seconds per behavioral question
- Ask for follow-up questions — real interviewers always dig deeper
After the Mock Interview
- Write down feedback immediately — you'll forget specifics within hours
- Focus on patterns — one weak answer is normal; the same weakness across multiple answers is what to fix
- Practice again within 48 hours — spaced repetition locks in improvements
How Many Mock Interviews Do You Need?
Most career coaches recommend 3-5 mock interviews before each real interview:
| Session | Focus |
|---|---|
| 1 | General practice — identify your biggest gaps |
| 2 | Work on weak spots from session 1 |
| 3 | Full simulation with the target company's likely questions |
| 4-5 | Polish delivery, timing, and confidence |
With AI tools, you can easily fit in more sessions since there's no scheduling friction.
Mock Interviews vs. Other Preparation Methods
| Method | Pros | Cons |
|---|---|---|
| Mock interviews | Simulates real pressure, builds muscle memory | Requires a partner or tool |
| Practicing in your head | Easy, no setup needed | Doesn't build speaking skills or handle pressure |
| Writing out answers | Helps organize thoughts | Written ≠ spoken; you'll sound scripted |
| Recording yourself | See how you come across | No follow-up questions or feedback |
| Reading guides | Builds knowledge | Doesn't translate to performance under pressure |
The most effective approach: read guides for knowledge, then do mock interviews to turn that knowledge into performance under pressure.
