Interview practice at home: how to run a mock interview out loud on your own

Most people prepare for an interview by reading their notes in their head. Then the first question comes, and the answer that sounded fine in their head comes out in a tangle.

The fix is not more reading. It is saying your answers out loud before the day.

If you are not yet sure which job you are preparing for, start with the free three-minute Career Change Check at changingcareers.com.au/assessment. It shows Australian roles people in your kind of work have moved into. Practice works best when it is aimed at one kind of job.

This guide shows you how to run a mock interview at home, on your own, in about 45 minutes.

Why out loud beats reading

Thinking an answer and saying it are different skills. You can know exactly what you mean and still lose the thread when you try to say it under pressure.

Saying answers out loud does three things:

It shows you where an answer falls apart.
It gets you used to the words, so they come more easily on the day.
It makes the real interview feel less strange, because you have done something like it before.

Reading your notes again does none of that.

What you need

a quiet room and 30 to 45 minutes
8 to 12 questions for the job you want
your phone, to record yourself
a timer
paper for notes

You do not need a partner or any special software.

Step 1: choose your questions

Do not use a list of 50 generic questions. Pick 8 to 12 that fit the job.

The best source is the job ad or position description. Take each main duty and turn it into a question that starts with "Tell me about a time you..." Those are the questions most likely to come up. Our post on reading a job ad shows how to pull the main duties out.

For customer service, claims, admin and coordination roles, a starting list might be:

About things you have done

Tell me about a time you dealt with an upset customer.
Tell me about a time you had too many things due at once.
Tell me about a mistake you made at work and what you did next.
Tell me about a time you explained something complicated to someone who was confused.

About the move

Why do you want to leave your current kind of work?
What do you know about this role?

Scenario questions

A client is upset and you do not have the answer they need. What do you do?
Three tasks are due at the same time. How do you decide what comes first?

The last one

Step 2: set up like it is real

This sounds minor. It is not.

Sit at a table, not on the couch. Dress the way you would for the interview, at least from the waist up. If the real interview is on video, put your phone at eye level and check what is behind you.

Then press record. Do not skip this. You will not notice your own habits, like filler words, looking away or trailing off, unless you watch yourself back.

Step 3: use a simple shape for "tell me about a time" answers

Many interviewers ask for a real example rather than a general statement. A common shape for the answer is STAR:

Situation: where you were, in one or two sentences
Task: what you had to do
Action: what you did, step by step (the longest part)
Result: what happened, and what changed because of you

Aim for about 90 seconds to two minutes. If you finish in 30 seconds, add detail. If you are still going at three minutes, cut the set-up.

Say "I", not "we", in the action part. The interviewer is judging you, not your team.

If you are short of examples, our post on transferable skills examples lists the kinds of moments call centre, customer service and admin work produce every week.

Step 4: run the mock interview

Read the first question out loud, as if someone else is asking it. Then answer it out loud, to the camera, with the timer running.

Do not stop to fix yourself halfway through. Finish the answer, then write a quick note:

Did I answer the question that was asked?
Was my example specific?
Did I say what the result was?
Did I say "um", "like" or "sort of" a lot?

Then move to the next question. Do not watch the recording until you have done every question.

Step 5: watch it back

This is uncomfortable. Do it anyway.

Watch once with the sound off. Look at your posture and where your eyes go. Then watch with the sound on and listen for:

answers that wander and never reach a result
places where your voice drops or you lose confidence
general statements where a real example should be

Pick two or three things to fix. Not ten.

Step 6: redo the weakest answers

Choose the two or three weakest answers. Jot down a few new notes for each one, then record them again.

You are not looking for perfect. You are looking for an answer that is clear, specific and ends with a result. When you have that, stop.

How many times to practise

Three short sessions in the week before an interview suits most people:

Five to seven days before: run the full mock and find the weak spots.
Two to three days before: redo the weak answers and add any new questions.
The evening before: run four or five of the likeliest questions in about 20 minutes, then stop.

More than that can make your answers sound learned off by heart. You want to sound like yourself.

The question career changers fumble most

"Why are you leaving?" comes up in almost every interview for a career change, and it is the one people practise least.

A plain, honest answer works. For example:

"I've been in customer service for eight years and I'm good at it. Over time the work has narrowed, and I want a role where I look after more complex cases and stay with them through to the end. That is what drew me to this job."

Write your own version, then say it out loud until it sounds natural. Our guide on how to explain a career change in an interview has more example answers.

If the interview is a recorded video

Some employers now use one-way video interviews as a first step. You record your answers with no one on the other end. It feels strange the first time.

The method above is close to the real thing, so practising on camera at home is good preparation. Look at the camera, not at your own face on screen. Speak a little slower than feels natural.

When to get help

Practising alone gets you most of the way. A second opinion helps most when:

you have had two or more interviews for similar roles and not gone further
you are changing industries and are not sure your examples carry across
the role is a big step up

The Sprint is A$299 for twelve weeks and includes interview practice answered out loud, built from a real job ad you bring in, with feedback after each answer. It also includes up to three reviews from a real Australian career coach on a targeted resume or an application pack, plus unlimited messages to that coach.

Frequently asked questions

How do I practise for a job interview on my own?

Pick 8 to 12 questions from the job ad. Sit at a table, record yourself on your phone, and answer each question out loud as if someone is asking it. Watch the recording back, note where answers were vague or had no result, and redo the weakest two or three.

What is a mock interview?

A mock interview is a practice run of a real interview. You answer likely questions out loud, under conditions close to the real thing, then review how it went. You can do one with a friend, with a coach, or on your own with a phone camera.

What is the STAR method?

STAR stands for Situation, Task, Action, Result. It is a simple shape for answering questions that ask for a real example from your work. Keep the situation short, spend most of the time on what you did, and always finish with the result.

How many times should I practise before an interview?

Three short sessions in the week before suits most people: a full mock about a week out, a redo of the weak answers two or three days before, and a 20-minute run of the likeliest questions the evening before.

What if I do not have good examples from my job?

Most people have more than they think. If you work in a call centre, claims, scheduling or admin, you have dealt with upset customers, competing deadlines, mistakes that needed fixing and confusing rules that needed explaining. A specific, ordinary example beats a dramatic one.
