[Essential Guide] What They’re Really Looking For in Japanese Engineering Interviews!

“As long as I have strong technical skills, I’ll get hired”—that’s what many foreigners who want to work as engineers in Japan initially think. It’s true that technical skills are a prerequisite. However, in Japanese engineering recruitment, how you approach your work, your mindset, and your communication style are valued just as much as your technical skills.
What recruiters are really assessing is whether they can work with this person every day and whether the candidate will be able to contribute to the team over the long term. In this article, a foreign engineer who has undergone numerous interviews in Japan offers an honest breakdown of the factors that tend to earn high marks and those that often lead to rejection.

Why Japanese job interviews are said to be “unique”

Some people feel that engineering interviews in Japan are more relaxed and involve more small talk compared to those overseas. It’s not uncommon for them to proceed with little pressure, almost like a casual conversation. However, behind that atmosphere, your attitude in responding, the thoroughness of your explanations, and your level of understanding are being closely observed.

A key characteristic of Japanese interviews is that they focus less on direct self-promotion and more on assessing “how you think and act.” Even if the atmosphere appears calm on the surface, evaluations are being conducted quietly and thoroughly. It is not uncommon for candidates to think, “I was able to speak comfortably, so I must have done well,” only to later realize that every detail was being scrutinized. Understanding this premise is the first step in your preparation.

In technical problems, the “thought process” is valued more than the “correct answer”

In technical interviews in Japan, you’re more likely to encounter questions that are closer to real-world scenarios than difficult algorithm problems. These are practical questions, such as “How would you investigate this bug?” or “How would you handle it if the team’s specifications were vague?” Even if you can’t provide a perfect answer, that in itself isn’t a major issue.
What matters most are three things: “how you approached the problem,” “how much you understand,” and “how you explain what you don’t know.” Even if you get stuck partway through, you’ll be highly regarded if you can verbalize your thoughts to organize them. It’s more important to demonstrate the willingness to articulate your thinking—saying something like, “I’m currently thinking along these lines”—than to freeze up in silence. What the interviewer wants to see isn’t a “finished answer,” but the “thought process.”

In Japanese, the willingness to communicate is more important than fluency

There are many foreign engineers who have secured job offers even though their Japanese isn’t perfect. In fact, an increasing number of companies prioritize “whether we can work together” over Japanese language proficiency when hiring. What is valued is sincerity—whether you can ask questions when you don’t understand, whether you take the time to confirm details, and whether you listen to the other person until the end.

A proactive willingness to communicate is valued more highly than grammatical accuracy. Even if you can’t speak fluently, people who politely ask for clarification—such as “Could you please confirm that again?” or “Is my understanding correct?”—are highly trusted in the Japanese workplace. Since this same attitude is expected in daily work, demonstrating even a glimpse of it during an interview will boost your evaluation.

The Right Way to Answer “Why Japan?” and “Why Our Company?”

These two questions almost always come up. And this is where many foreign engineers stumble. The key is not to base your answer solely on salary or working conditions. While “the pay is high” or “it’s easy to get a visa” may be your honest feelings, those reasons alone won’t impress the interviewer.

By linking your answers to the technology, project details, team atmosphere, and growth opportunities, you can convey your genuine commitment to the company. If you research the company’s services, the technologies they use, and their development style in advance, and can articulate your reasons for wanting to work there in concrete terms, you’ll stand out significantly from other candidates. Your depth of understanding of the company directly translates into a sense of your commitment.

×Common Mistakes in Self-Promotion

There are two common mistakes foreign engineers tend to make. One is exaggerating their achievements, and the other is emphasizing individual contributions too much. Saying something like, “I built the entire system all by myself,” can come across as a bit jarring to Japanese interviewers.

Japanese companies place great importance on “what role you played within the team” and “how you handled problems when they arose.” By saying something like, “In a team project, I was responsible for this part and implemented these improvements,” you convey a balance of humility and specificity. There’s no need to downplay your contributions; what’s important is to frame them within the context of the team.

Follow-up questions are seen as a “barometer of motivation”

The “reverse question”—when you’re asked, “Do you have any questions?” at the end of the interview—is extremely important. Saying “No, not really” can be interpreted as a lack of interest in the company. This is your chance to demonstrate that you have a clear vision of what it would be like to work there.

Questions that help boost your evaluation are those that demonstrate how you envision yourself working there, such as inquiries about team composition, technologies used, performance evaluation systems, and growth opportunities after joining. It’s safer to save questions regarding compensation and benefits for the end. Preparing two or three questions in advance and tailoring them to the flow of the conversation will better convey your enthusiasm for joining the company.
