7-Day Interview Sprint for India Placement Season
Structured day-by-day DSA, system design, and review inside PrepOS — tuned for college students and working pros with a deadline.
Final-week prep is not about learning every topic — it is about sequencing what you already half-know. PrepOS ships a 7-day sprint on the desktop: daily themes, tie-ins to focus sessions, and study modes for Placement Prep or DSA Grind.
Day-by-day rhythm (template)
- Day 1–2: Arrays, strings, hashing — timed sets on LeetCode / GfG.
- Day 3–4: Trees, graphs, BFS/DFS — one hard problem with Capture→AI debrief.
- Day 5: System design fundamentals — ByteByteGo feed + Excalidraw window.
- Day 6: Mixed revision — Problem of the Day widget + weak topics.
- Day 7: Mock + rest — light review, lockdown mode off, sleep.
College vs working pro personas
On first launch PrepOS asks whether you are a college student or working professional and how many days until your interview. Under seven days triggers the sprint automatically. Working pros might lean on Revision mode; students often live in Placement Prep with GfG and Striver feeds pinned.
Pair the sprint with focus lock
Each sprint task can start a focus session on the app you are using (LeetCode window, Notes, AI Chat). Enable Hard focus when deadlines loom — PrepOS blocks quitting until the timer completes. That is the difference between a Notion checklist and a cockpit that enforces depth.
