## 2️⃣ DSA Core (Interview Fuel)

| Resource | Why It Rocks |
| --- | --- |
| [Google TechDev DSA Path](https://techdevguide.withgoogle.com/paths/data-structures-and-algorithms/) | Bite‑sized, language‑agnostic |
| [Striver A‑to‑Z Sheet (2025)](https://takeuforward.org/interviews/strivers-sde-sheet-top-coding-interview-problems/) | 450 hand‑picked problems |
| [NeetCode Free Roadmap](https://neetcode.io/) | Guided patterns + video hints |
| [USACO Guide](https://usaco.guide/) | Interactive, Bronze→Platinum progression |

* * *

## 3️⃣ Contest Mode (Rating \> Cert)

- **Weekly Arena:** Codeforces, AtCoder, CodeChef Starters

- **Practice Filters:** [CFTracker](https://cftracker.dev) | [Kenkoo AtCoder Problems](https://kenkoooo.com/atcoder/)

- **Structured Courses:** [Codeforces EDU](https://codeforces.com/edu/courses) modules (Binary Search, Trees…)

> **Target:** 1600+ Codeforces OR 90 % AC on USACO Gold.

* * *

## 4️⃣ Mock Interviews & Patterns

| Tool | Type | Notes |
| --- | --- | --- |
| [Interviewing.io](https://interviewing.io/) | Anonymous engineer mocks | Free & un‑gated |
| [Pramp](https://www.pramp.com/#/) | Peer‑to‑peer | Audio + coder pad |
| LeetCode Discuss Patterns | Community crowdsourced | Tag‑wise archives |

* * *

## 5️⃣ Portfolio & Resume (Show, Don’t Tell)

- Build **2 mini‑projects** : CP helper CLI + REST Todo API.

- Ship on **GitHub Pages** ; link in résumé.

- Format with **[Reactive Resume](https://rxresu.me/)** (open‑source ATS‑friendly).

* * *

## 6️⃣ Power Tools (Quality‑of‑Life)

| Tool | Why |
| --- | --- |
| [CP Editor 7.0](https://github.com/cpeditor/cpeditor/releases) | 1‑click compile‑and‑run, code folding |
| [cf‑tool](https://github.com/aqua4/cf-tool-cpe) | Scrapes tests, automated submit |
| [AtCoder Library Problem Book](https://github.com/atcoder/ac-library) | Battle‑tested templates |

* * *

## 📅 Daily Loop

1. **15 m Warm‑up:** HackerRank 30‑Days / LeetCode easy.

2. **30 m Core:** One 1400‑rated Codeforces or ABC C.

3. **15 m Upsolve:** Fix yesterday’s wrong answer.

4. **Weekend:** Full 2‑hour contest + editorials.

* * *

## 🛑 Reality Checks

- Under **3 months**? Focus on DSA sheets & mock interviews.

- CP alone won’t teach system design; marry it with one solid project.

- Paying for “Alpha Plus” won’t guarantee offers—consistent solving does.
