Pathways: Full-Stack vs Front-End
Applicants must select at least one pathway when registering for the HENNGE coding challenge. The two pathways have different technical requirements and training structures.
| Area | Full-Stack Pathway | Front-End Pathway |
|---|---|---|
| Main focus | Back-end APIs, front-end interfaces, cloud deployment and DevOps | Front-end application development and integration with back-end/cloud systems |
| Key technologies | Python, Go, TypeScript, React/Vue, AWS | TypeScript, React/Vue, AWS |
| Application development | Weeks 1–3 | Weeks 1–4 |
| DevOps project | Week 4 | Week 5 |
| Additional assignment | Possible special assignment in Weeks 5–6 | Depends on programme structure and batch |
Candidates interested in both pathways can apply to both, but HENNGE requires separate applications using different email addresses for the respective coding challenges. After joining the programme, interns cannot switch pathways midway.

Duration and Work Schedule
HENNGE GIP normally runs for 4 to 6 weeks. Interns attend the programme onsite at HENNGE’s Tokyo headquarters from Monday to Friday, 10:00 AM to 7:00 PM Japan Standard Time.
The HENNGE internship states that batches have fixed starting dates because interns within a batch are expected to begin together. The duration can sometimes be shortened, but not below four weeks. Candidates who need a shorter period should discuss this during the interview stage.
HENNGE currently does not offer GIP as a remote internship. Applicants should therefore ensure that their university timetable or other commitments allow them to stay in Tokyo for the required period.

How to Apply ?
The HENNGE internship application has three main stages.
Step 1: Register and Select Your Pathway
Use the application option on the official HENNGE GIP page and select either the Full-Stack Engineering or Front-End Engineering pathway.
After registration, verify your email address to access the coding challenge.
Step 2: Complete the Coding Challenge
Applicants must complete HENNGE’s coding challenge before submitting their main application materials.
HENNGE states that the coding challenge has no time limit and that the amount of time an applicant takes to solve it is not used as a screening criterion.
Step 3: Submit Your CV and Cover Letter
After completing the challenge, submit the required application documents, including your CV and cover letter, and indicate your preferred internship batches.
HENNGE specifically advises applicants to explain their technical experience and motivations clearly rather than submitting generic application material.
Step 4: Attend the Interviews
Candidates who clear the coding challenge and document screening proceed to an HR interview followed by an online interview.
Applicants should be ready to discuss their projects, programming choices, technical reasoning and interest in joining an engineering environment in Japan.
Application Dates and Deadline
HENNGE does not currently publish one universal annual deadline for the Global Internship Program.
Instead, internships are organised into separate batches with limited capacity. Applications are reviewed as they are received, and HENNGE states that places are filled on a first-come, first-served basis. Applications for a particular batch can therefore close once all available slots are occupied.
Important: Do not rely on a third-party website’s stated HENNGE GIP deadline without checking the official internship schedule. The available batches can change as places are filled.
Candidates should check the official HENNGE Global Internship Program page for the latest batch availability before applying.
Selection Process
The HENNGE Internship program follows a multi-stage selection process designed to identify candidates who can contribute effectively to participate.
- Online registration and pathway selection
- Email verification
- Coding challenge
- CV and cover letter submission
- Internship batch preference submission
- HR interview for shortlisted applicants
- Online interview
- Final internship selection
The coding stage deserves particular attention because HENNGE expects candidates to demonstrate that they understand their own code and technical decisions rather than simply producing a working answer.
Can You Use AI for the HENNGE Coding Challenge or Internship?
HENNGE has published a specific policy on the use of artificial intelligence during GIP training.
The company asks interns not to use AI tools to generate code for training assignments or solution implementations. Submitted code should reflect the intern’s own understanding.
A designated AI service may be used for limited learning support, such as clarifying a technical concept, understanding documentation or assisting with non-essential tasks. Interns are still expected to explain their code, design decisions and technical trade-offs themselves.
Stipend and Benefits
The HENNGE Global Internship Program is unpaid. HENNGE nevertheless provides several forms of financial and logistical support to participating interns.
| Benefit | What HENNGE States |
|---|---|
| Monthly subsidy | Provided to support living expenses during the programme |
| Round-trip airfare | Covered subject to HENNGE’s programme conditions |
| Visa assistance | Pre-arrival support and visa guidance are provided |
| Medical insurance | Provided to interns who do not reside in Japan |
| Mobile phone | Japanese mobile phone with data |
| Technical learning | Mentoring, engineering assignments and Monthly Technical Sessions |
According to HENNGE’s page the living subsidy is intended to help cover regular expenses such as accommodation, meals, local transport and essential living costs.
For airfare, HENNGE states that round-trip travel can be covered when an intern arrives in Japan within the programme’s stipulated arrival window. Interns receive a flight budget and reimbursement according to HENNGE’s process.
HENNGE has not published a fixed subsidy amount on the current GIP page. Applicants should therefore avoid treating third-party stipend or allowance figures as confirmed unless HENNGE provides them directly during the selection process.
Do HENNGE Interns Need a Visa for Japan?
Visa requirements depend on the intern’s nationality.
HENNGE explains that because GIP is an unpaid internship with a subsidy, participants do not require a Japanese working visa specifically for the programme. Interns from countries that require a visa for short-term entry into Japan may need a short-term stay visa.
HENNGE provides guidance and financial assistance for relevant visa procedures. Applicants should follow the instructions provided by HENNGE after selection rather than arranging an employment visa independently.
What Will You Work on During HENNGE GIP?
The programme is designed around structured software engineering assignments rather than interns being assigned directly to normal production work.
Depending on the pathway, training can cover:
- Full-stack web application development
- Back-end API design
- Front-end application architecture
- React or Vue with TypeScript
- State management and data fetching
- Testing
- Unix-like development environments
- AWS deployment
- Cloud infrastructure
- DevOps concepts
- CI/CD
- Infrastructure as Code
- Technical decision-making and code reviews
Interns work with experienced Cloud Product Development engineers and receive mentor feedback throughout the programme.
HENNGE also runs Monthly Technical Sessions, where engineers share technical knowledge and discuss new technologies. HENNGE’s own account of GIP notes that interns may also make a short technical presentation during these sessions.
Can HENNGE GIP Lead to a Full-Time Job?
Potentially, but there is no automatic conversion from internship to employment.
HENNGE describes GIP as part of its pre-hiring process and states that outstanding participants may receive full-time employment opportunities. The official page states that interns interested in working for HENNGE after the programme can explore that possibility with the company.
Candidates interested in a long-term software engineering career in Japan should therefore treat the internship as a separate selection process while recognising that strong performance can create a route to further discussions with HENNGE.
How to Prepare ?
The screening process begins with a coding challenge and HENNGE publishes detailed technical requirements, preparation should focus on demonstrable engineering ability rather than collecting unrelated certifications.
1. Choose the Appropriate Pathway
Select Full-Stack if your strongest work covers back-end development, APIs, front-end development and cloud or DevOps concepts. Choose Front-End if your portfolio is stronger in TypeScript, React/Vue, application state, UI implementation and client-side architecture.
2. Review Unix and Git Workflows
Both pathways expect applicants to be comfortable working in Linux, macOS or another Unix-like environment. Applicants should be able to work with the command line and explain how they manage and test their code.
3. Strengthen the Skills Listed for Your Pathway
For Full-Stack applicants, this can include Python or Go, TypeScript, APIs, containers, AWS and CI/CD. Front-End applicants should be particularly comfortable with React or Vue, TypeScript, state management, data fetching, testing and responsive application development.
4. Prepare to Explain Your Code
HENNGE’s published AI policy makes this especially important. Do not prepare only for whether your solution works. Be ready to explain why you chose an approach, what alternatives you considered and what trade-offs your implementation creates.
5. Make Your Cover Letter Specific
Connect your existing engineering experience with the pathway you selected and explain why an onsite engineering programme in Japan fits your career plans. HENNGE itself warns that generic applications may not communicate a candidate’s potential effectively.
