Mock Interviews
How to Do a Mock Interview at Home, Alone or With a Friend
By the Upinterview team · Published · 8 min read
Most people prepare for interviews by reading: articles, question lists, their own resume. Reading is the wrong exercise. Interviews are spoken, timed and a little uncomfortable, and the only way to get better at that is to do it out loud. You can do this at home with nothing more than a phone.
Set it up like the real thing
Half the benefit of a mock interview comes from the pressure, and pressure needs a few small rules. Decide on one specific role and keep the job description open. Write your questions in advance or pull them from a list such as our mock interview questions and answers. Find a quiet spot, set a timer, and put your phone on silent.
Wear what helps you take it seriously. For some people that is a shirt. For others it is just sitting at a desk instead of on the sofa. Either is fine. What matters is that you do not treat it as a chat.
Practicing alone
Solo practice is the easiest to fit into a week, and it works better than most people expect, provided you record yourself.
- Pick eight to ten questions across types: two or three behavioral, one about the role, one about your background, and one you dread. Shuffle them so you do not know the order.
- Set your phone or laptop up to record, camera at eye level. Read one question, count to three, and answer.
- Cap each answer at two minutes. If you are still going at two minutes, that is your first finding.
- Do not watch the recording straight away. Give it a few hours so you are more critical and less embarrassed.
When you do watch it, keep a simple note sheet with three columns: did I answer the question that was asked, did I give a specific example, and did I end cleanly or trail off. Count filler words if you want, but do not obsess over them. A few "ums" cost you far less than a vague answer.
Practicing with a friend
A friend adds the one thing solo practice cannot: another human reacting to you. The trouble is that friends are polite. Brief them before you start.
- Give them the job description and a list of questions, and tell them they can ask their own.
- Ask them to interrupt with follow-ups such as "what did you personally do?" or "how did you know it worked?"
- Ask them to write things down during the answer rather than commenting. It stops them nodding you along.
- Finish with three questions: where did you lose interest, which answer was vague, and what would you cut.
The follow-up problem
There is a real hole in solo practice: nobody asks the follow-up. In a live interview, the first answer is rarely the end of it. The interviewer pushes on it. "And what was your role in that?" "What would you do differently?" A story that sounded polished can fall apart on the second question.
You can patch this yourself by writing two follow-ups beneath each answer and forcing yourself to answer those too. Or you can use an AI interviewer, which is built to ask them. Our free mock interview does this and gives feedback afterwards, which makes it a decent stand-in when no friend is around.
Practicing for a video interview
Video adds its own problems. You are answering a screen, and there is no visible reaction to tell you whether you are on track. Practice looking at the camera lens when you speak, not at your own face. Check the light: a window in front of you is better than behind you. Do a full dress rehearsal on the platform you will actually use, because audio settings have a way of misbehaving on the day.
A rough week of practice
| Day | What to do |
|---|---|
| Day 1 | Write down five or six real stories from work: a success, a failure, a conflict, a time you led, a time you learned something. |
| Day 2 | Record yourself answering eight behavioral questions. |
| Day 3 | Watch the recording, take notes, and rewrite your two weakest answers. |
| Day 4 | Run a session with a friend, including follow-ups. |
| Day 5 | Practice the technical or role-specific part of the interview. |
| Day 6 | Do one full-length, timed mock interview from start to finish. |
| Day 7 | Rest. Skim your notes. Do not cram. |
What to do with the feedback
Resist the urge to fix everything at once. After each session, choose one thing to change: shorter openings, a stronger example, slower delivery. Then run the same question again and check whether it worked. One fix you actually make beats a page of notes you never open.
If you want to see what interviewers are looking for behind these questions, what a mock interview is and how it works covers the formats in more detail.
Frequently asked questions
Can I do a mock interview by myself?
Yes. Record yourself answering timed questions, then review the video a few hours later. Add your own follow-up questions, since nobody will ask them for you, or use an AI interviewer that does.
How long should a mock interview at home be?
Thirty to forty-five minutes is enough for a full session. For daily drills, ten or fifteen minutes on a single question type works well.
What should I wear to a mock interview at home?
Whatever helps you take it seriously. If your real interview is on video, it is worth doing at least one full rehearsal dressed as you plan to be on the day.
How do I practice for a video interview?
Record yourself on the actual platform you will use, look at the lens rather than the screen, and check your lighting, audio and internet connection ahead of time.
