5 Questions You Must Ask at Every Job Interview

"Why didn't I ask anything back then?"

Lisa (24) from Manila lay in bed one night during her 4th month of work, thinking that over and over. She couldn't stop crying.

The interview was in January 2024. A food factory in Kanagawa. A friend had referred her, saying the conditions were good. The recruiter was warm and welcoming from the start. "We're looking for global talent." "We have a lot of international staff, so language support is solid." A gentle smile. A clean office. A prepared chair and tea.

Lisa wanted to ask questions — but she couldn't.

The moment she was about to say "I'd like to check the salary breakdown," he said, "Oh, we'll explain all that properly after you join." She had wanted to ask about deemed overtime, but the conversation moved too quickly and she couldn't find an opening.

In an interview, all the pressure is on the candidate. The other side is a professional; you are not. Anyone who has interviewed in Japan knows how hard it can be to say "May I confirm something?" when you're not used to negotiating in Japanese.

In the end, Lisa gave the OK sign that day. "Monthly salary ¥220,000 / light overtime / visa support available." Those words from the listing were in her head.

When her first payslip arrived, reality hit. Base salary: ¥172,000. The remaining ¥48,000 was labeled "deemed overtime (40 hours included)." Her actual overtime was 50–60 hours a month, but those 40 hours were "already paid" — no additional payment was made. When she asked HR about "visa support," they said, "Let's look into it together when the time comes."

The following year during visa renewal, she was told there might be a mismatch between her job duties and her residence status. She had to apply for a visa status change — at her own expense.

In four months, everything had changed.

If she had asked five questions at the interview — that's what Lisa says now. Write your question list on paper before the interview, bring it with you, and preface each question with "May I confirm this?" That one preparation can change what comes after.

An interview is not just a place where a company chooses you — it's also a place where you choose the company. Use the following five questions at your next interview.

01."What is the base salary? Is deemed overtime included?"
"Monthly salary ¥220,000" may not be the base salary — it may include 45 hours of deemed overtime. Ask separately: "What is the base salary?" And always ask: "Is overtime paid additionally on top of that?"
02."Are there employees working here on the same visa type as me?"
This confirms whether the job duties are allowed under your visa. "We'll look into it" or "Let's figure it out after you join" are warning answers. A mismatch can require a costly visa status change later.
03."Are employees actually able to take paid leave?"
By law, 10 days are granted after 6 months. "The system exists" and "people actually use it" are different. Ask specifically: "How many days did employees use on average last year?"
04."Does the company cover housing or commuting costs?"
Conditions vary: company dormitory, full commuting cost coverage, or a cap on the allowance. Even with ¥220,000 salary, your take-home can change significantly if commuting is out-of-pocket.
05."Can you explain the difference in salary between trial period and after joining officially?"
Some companies pay less during the trial period (usually 3 months). Some also illegally withhold social insurance during the trial period. Ask together: "Will I be enrolled in social insurance during the trial period?"
Lisa later changed jobs through GloJob's career counseling. At her new workplace, the hiring manager pulled out a document during the interview and said, "Let's check the salary breakdown together." Companies that are honest in hiring welcome your questions.
