You can work remotely **2 days a week**, and your home office stipend is **€900**. Since you joined on 15 September 2026 (on or after 1 September 2026), the amendments in §7 apply: the intern remote-work allowance rises from 1 to 2 days a week (§7, amending §2), and the home office stipend increases from €600 to €900 (§7, amending §3).

DeepSeek V4.1 Flash
Passed: Stated all 3 facts with the section.
**Remote work: 2 days a week.** §2 sets interns at 1 day, but §7 (amendments of 1 September 2026) raises intern remote work to 2 days a week, and you joined on 15 September 2026, so the new figure applies. **Stipend: the handbook doesn't clearly say.** §7 does set the home office stipend at €900 "for everyone who joins on or after 1 September 2026," which would cover your start date. But the stipend itself is granted in §3 only to "new **staff**," and the handbook never states whether interns count as staff for this purpose. So the €900 figure is stated (§7), but whether an intern is entitled to any stipend at all isn't covered in the handbook.

* **Remote work:** You can work remotely up to 2 days a week (§7). * **Home office stipend:** Whether interns receive a home office stipend isn't in the handbook (the handbook specifies that "New staff" receive the stipend (§3), amended to €900 for those joining on or after 1 September 2026 (§7), but does not state if interns are included in "staff").

Claude Opus 5.5
Passed: Stated all 3 facts with the section.
- **Remote work: 2 days a week.** §2 sets interns at 1 day, but the 1 September 2026 amendment raises this to 2 days (§2, §7). - **Home office stipend: €900, if interns are eligible.** For anyone joining on or after 1 September 2026, the stipend is €900 instead of €600 (§3, §7). However, §3 grants the stipend to "new staff," and §2 treats "staff" and "interns" as separate groups. The handbook doesn't say whether interns get the stipend, so it's worth confirming with the People team.
