Mock Interviews: How to Practise So It Actually Works

How to run a mock interview that feels like the real thing: choosing a partner, setting scoring criteria and using feedback to improve each round.

Many people prepare for interviews by reading questions and thinking through answers in their heads. On the day, the sentences they planned don't come out the way they intended, because thinking silently and speaking aloud in front of someone are different skills. A mock interview closes that gap, and done the right way, just a few rounds can clearly change how you answer.

What is a mock interview?

A mock interview simulates the real thing as closely as possible: someone asks the questions, time is limited and feedback follows. Unlike memorising answers, you have to handle unprepared questions, follow ups and the small pressure that comes with a real conversation.

Prepare before you practise

Choose questions that fit the role

Choose a practice partner

The best partner is someone who has interviewed others or works in the field you are applying to. Next best is a friend willing to be blunt. Send them the job description and the questions you want asked in advance, and ask them to probe whenever your answer is unclear. If you can't find anyone, practising with AI works too; see practising interviews with AI.

Make the round feel real

  1. Dress and sit as you will on the day: for online interviews, use the same camera, mic and background
  2. Keep time: don't let answers run long; going past two minutes usually means the story isn't organised yet
  3. Don't stop midway: if you stumble, recover as you would on the day instead of asking to restart
  4. Record video: ask your partner's permission and record it to review later
Practise harder than the real day, and the real day will feel easier than you expected.

Give feedback that can be used

Feedback like "That was fine" doesn't help. Ask your partner to score every answer on the same criteria.

Ask your partner to pick your weakest answer and say what they would doubt if they were on the panel. That is the first thing to fix.

Use video to review yourself

Watching yourself can be uncomfortable, but it is the fastest way to spot problems. Watch once on mute to check body language, then once audio only to count filler words like "um", "like" and "so". Note which answers start slowly or end without a conclusion. If you feel very nervous while practising, also read managing interview anxiety.

Practise handling follow-up questions

In real interviews, panels rarely stop at the first question. They ask "Why did you choose that approach?", "What would you do differently?" or "Which part did you do yourself?" Ask your partner to probe at least two levels deep on every story you tell. If you can't answer the second level, the story isn't ready yet; go back over the details, such as the relevant numbers, who you worked with and what you learned.

Example drill

You say "I cut the time it takes to produce the monthly report." Your partner follows up: "How? Who approved the change?" and "Did anyone disagree?" Second and third level questions like these are what separate the person who actually did the work from someone who was just on the team.

Mistakes that stop practice from helping

How to start

  1. Pick eight to ten questions from a job description you are actually applying to
  2. Write the key points of each answer as short bullets, not full paragraphs
  3. Book at least two rounds with a partner, a few days apart
  4. After each round, choose only two or three things to adjust, then practise the same questions again
  5. Do a final full-length round, from greeting to asking your own questions
