How to practice for a job interview alone

Why practising alone still works

Most weak answers are not weak because of what you know. They fall apart when you say them: you ramble, forget your best example, or never reach the result. That part improves with repetition, and repetition is something you can do on your own, at any time, as often as you need.

A routine for one session (about 30 minutes)

1. Pick five to eight questions. Take them from the real job ad: its duties and requirements are what you will be asked about. Add the openers that come up almost everywhere, such as tell me about yourself and why this role.
2. Stand up and answer out loud, in full. No skipping the hard ones, no “and then I would say…”. Speak the whole answer as if someone were listening.
3. Time every answer. One to two minutes for most questions, 60 to 90 seconds for “tell me about yourself”.
4. Record yourself on your phone, audio is enough.
5. Listen back with a checklist (below), one answer at a time.
6. Redo the two weakest answers straight away, then once more the next day.

What to listen for

• Did you answer the question asked? The first sentence should say the point.
• Length. Past two minutes, the listener drifts.
• A concrete example, with a number or a visible result.
• “I” for your part. “We” hides what you did.
• Filler words and restarts. A short pause sounds better than “um”.

Practising behavioral questions alone

Behavioral questions (“Tell me about a time when…”) are the easiest to practise alone, because the stories are yours. Write five or six real stories as bullet points, not scripts, in the STAR order: situation, task, action, result. Then tell each one out loud in about two minutes, spending most of the time on what you did. Retell the same story for different prompts (conflict, mistake, pressure, leading) so you get used to adapting it. The STAR method generator checks your “I” versus “we” and your numbers as you write.

Make it feel less like rehearsal

• Shuffle the questions so you cannot prepare them in order. The interview question generator picks them at random, reads them out loud and runs a 2-minute timer.
• Hear the question instead of reading it. The free interview simulator speaks five questions one after the other in your browser.
• Practise in the setting you will have: dressed for it, sitting at the desk for a video call, or standing with your phone for a phone screen. See phone and video interview practice.

What practising alone cannot do

On your own, nobody interrupts you, asks a follow-up or reacts to a vague answer, and it is easy to be too kind to yourself when you listen back. Before an important interview, try at least one run where someone, or something, asks the questions and pushes back.

Practise with an interviewer that talks back

Readyo is an iPhone app for exactly this: an AI interviewer asks your questions out loud, from a job ad or a role you type, and may ask a short follow-up. You answer by voice; silence does not end your turn, and you can redo an answer. The report scores relevance (20 %), structure (20 %), evidence and precision (30 %), clarity and expression (15 %) and composure and ownership (15 %), with an improved version of each answer built only from what you said. Interviews run in English, French, Spanish or Arabic. It is practice only, never for use during a real interview; the app is free to download and interviews are paid.
