The best ways to practise for a technical interview
Most people preparing for a technical interview need three things: knowledge of what is asked, repetitions answering out loud under time pressure, and honest feedback on how it went. No single kind of practice gives all three. Courses and question banks give knowledge, peers and paid interviewers give realistic repetitions and human feedback, and AI interviewers give repetitions on demand. Pick by the gap you have.
Five kinds of practice
| Kind of practice | Good for | Limits |
|---|---|---|
| Practising alone | Free and flexible. Good for learning patterns and reading solutions. | No one asks follow-ups, interrupts or notices that you went quiet. Easy to overrate how well you would explain it. |
| Peer mock interviews | A real person, often free. You also learn by interviewing the other person. | Quality depends on your partner; scheduling takes effort; feedback is rarely calibrated to a level. |
| Paid mock interviews with experienced interviewers | The closest thing to the real round, with feedback from people who have run interviews. | The most expensive option per session, so most people can afford only a few. |
| Courses and question libraries | Structured learning, worked solutions, videos and community. | Reading a strong answer is a different skill from giving one out loud. |
| AI mock interviewers | Available any time, cheap or free per session, so you can get many repetitions. | An AI is not a person; its feedback shows how one practice went, not how a specific company would decide. |

It is for repetitions: it has no course, no human interviewers and no peer matching.
Questions
How many mock interviews should I do before a real one?
There is no fixed number. A common pattern is several low-cost repetitions per round type until you stop freezing and run out of time less often, then one or two higher-stakes mocks close to the date.
Is an AI mock interview as good as a human one?
They do different jobs. An AI interviewer is good for frequent repetitions on demand; a person who has run real interviews gives judgment and context that an AI cannot. Many candidates use both.
Which option is free?
Practising alone, peer mock interviews on several platforms, and the free plans of some AI tools, Mockich included. Paid human mock interviews are the most expensive option.
