Prepare with your own experience
A practical routine for your next Japanese interview
A useful practice session starts with one real project, one question, and an answer you can explain in your own words. PrepCue helps you repeat that cycle. You do not need to memorize a long script or sound like a native speaker to make your responsibilities clear. Start with the work you actually did, choose the details relevant to the role, and practise saying them in a concise order. The exercises below are preparation suggestions, not a prediction of any employer’s interview questions.
Turn your career sheet into a clear project story
Choose a recent project that you can discuss without disclosing confidential information. Write down its purpose, your role, the period you worked on it, the technology you personally used, and one problem you helped solve. Separate the team’s result from your own contribution. “Our team migrated the service” and “I wrote the migration checks” describe different responsibilities, and that distinction gives an interviewer something concrete to ask about. Remove client names, private URLs, credentials, and details you are not allowed to share before uploading materials.
Practise a short answer to 「担当したプロジェクトについて教えてください」. Begin with the purpose, move to your responsibility, and finish with one decision or lesson. Then prepare a longer version for follow-up questions: why you chose that approach, how you checked it, and what you would change next time. If you cannot verify a performance figure or business result, leave the number out. A specific, modest explanation is more useful than a polished claim you cannot defend.
Rehearse technical questions beyond memorized definitions
Use your own technology choices as the starting point. Questions such as 「なぜその技術を選びましたか」, 「障害の原因をどう調べましたか」, and 「品質をどのように確認しましたか」 help you practise explaining reasoning, diagnosis, and verification. State the constraint first: delivery time, existing systems, available skills, or a reliability requirement. Explain the option you chose, an alternative you considered, and the trade-off. You do not need to pretend that every project involved a complex architecture. A small, well-explained decision can show how you work.
After your first answer, add one follow-up: “What evidence supported that choice?” or “What would you do if the same issue happened again?” In PrepCue, review the feedback and compare the suggested response with your resume. Keep the parts supported by your experience and rewrite the rest. If a question concerns a technology you have not used professionally, say so and distinguish study, a personal project, and production experience. Practise explaining a proposed approach as a future action, rather than describing it as something you already delivered.
Prepare for SES project discussions with a skills map
For an SES-related project discussion, compare the project description with your career sheet before rehearsing. Make three small lists: work you have done independently, work you have done with support, and requirements you have not yet used. Include project phases such as design, implementation, testing, or operations only where they reflect your real responsibilities. A useful answer connects one requirement to one concrete example. Listing every technology on your resume without explaining your involvement makes it harder for the other person to understand where you can contribute.
Try 「この案件で活かせる経験は何ですか」 and 「未経験の技術にはどう対応しますか」. Explain the relevant experience first, identify any gap honestly, and describe how you would clarify the scope or learn what is missing. Prepare questions about the team, the work you would own, review practices, and the initial expectations. Confirm working conditions and the nature of the discussion with your contact; the purpose and process can vary by organization. PrepCue supports rehearsal, but it does not verify a project’s terms or decide whether the role is a good match for you.
Prepare useful reverse questions — 逆質問
Reverse questions are a chance to understand the work, not a test of how many questions you can ask. Start with something that remains unclear after reading the job or project description. For example: 「入社後、最初の三か月で期待される役割を教えていただけますか」 asks about early expectations. 「設計やコードのレビューはどのように進めていますか」 asks how the team checks work. 「現在、チームで改善したい技術的な課題は何ですか」 opens a discussion about real technical needs. Choose questions whose answers would help you prepare for the role.
Prepare two or three questions and a short reason for each. During the interview, adapt them to what has already been explained instead of reading the list unchanged. Rehearse asking a clarification politely when you miss a word: 「確認させてください。こちらは設計段階のお話でしょうか」. Finish a practice session by noting one answer to improve, one fact to verify, and one question to ask next time. That gives your next session a concrete starting point and makes progress easier to judge than simply repeating an entire interview.
Questions about practising with PrepCue
- What is PrepCue?
- PrepCue is an AI interview practice tool for engineers preparing for interviews in Japan. Its mock interview flow uses your resume and preparation materials to generate questions and feedback. A separate live assistant provides transcription and reference answers. The product supports Japanese and English interviews; the interface is available in English, Chinese, and Japanese.
- How should I start a mock interview?
- Open the mock interview tool, add a resume or paste relevant experience, and check that the extracted content is accurate. Select the interview settings offered in the tool, generate questions, and answer one at a time. Read the feedback, correct unsupported details in any reference answer, and practise your revised answer in your own words.
- Is PrepCue free to use?
- Mock interviews provide a limited guest trial. Signed-in mock interview actions use credits under the current usage rules. The live assistant requires sign-in; transcription has a daily free allowance, credit charges beyond that allowance, and a balance check before starting. Reference-answer generation in the live assistant does not itself deduct credits. See the pricing page for current limits and costs.
- Can I use a Japanese skills sheet or resume?
- The mock interview flow accepts pasted text, PDF files, and Excel files, including Japanese-style technical career sheets. Check the extracted project details before practising: formatting and source quality can affect parsing. Use material you are allowed to share, remove sensitive client information, and correct any missing or inaccurate responsibilities before relying on the generated questions.
- Are preparation materials stored?
- The two tools handle materials differently. Mock interview resumes and preparation materials are stored to support the practice workflow. Live-assistant materials are held in the browser session and sent with generation requests, rather than saved in our database. Requests are processed by the providers described in the privacy policy. Review that policy before sharing personal or confidential information.
- Can I use the suggested answer as my own experience?
- Only keep statements that are true for you. AI feedback and sample answers can contain mistakes or assumptions; they are practice aids, not evidence of work you have done. Check project names, responsibilities, technologies, and results against your source materials. If using assistance during an actual interview, follow the interviewer’s rules and obtain any permission required for recording or transcription.
