- Two pathways:
- Full-Stack: application development (weeks 1–3), DevOps and infrastructure (week 4), and a possible special assignment (weeks 5–6)
- Front-End: application development training (weeks 1–4) and a DevOps project (week 5)
- Outstanding interns may receive a full-time job offer in Japan
