The Definitive Interview Prep Roadmap

What this roadmap covers

This is the complete path, start to finish: it doesn't assume you've already found the right courses or the right order to take them in — it sequences everything on the platform built for interview preparation into one guided journey, with a practice step immediately after every theory course so you apply what you just learned before moving on.

The five pillars, plus two rounding-out rounds

1. DSA Patterns — 20 patterns, 80 hand-verified practice problems (two pointers, sliding window, hash tables, binary search, DFS/BFS, dynamic programming, backtracking, trees & BST, heaps, linked lists, intervals, graphs, greedy, prefix sum, monotonic stack, tries, bit manipulation, two heaps, cyclic sort, matrix traversal)
2. Coding Interview — the process itself: a repeatable framework for solving problems live, the mistakes that sink otherwise-strong candidates, and how to communicate while you work
3. System Design Interview — scalability, load balancing, caching, databases at scale, async messaging, and the five-step framework for running the interview itself, paired with named practice problems
4. Low-Level Design Interview — OOP, SOLID, and the GoF patterns interviewers actually ask about, paired with practice problems like Design a Parking Lot and Design an Elevator System
5. Company-Wise Problems — every DSA problem tagged with the companies it's genuinely well-known to be asked at, filterable by company on the practice page

Plus Concurrency (threads, locks, deadlock — the round asked at backend/systems-focused interviews) and Behavioral (STAR-formatted practice questions with an AI interviewer to rehearse against), and a final polish course on CV/LinkedIn optimization.

How to use it

Work through the steps in order. Every course step is immediately followed by a practice step on the matching track — don't skip the practice steps; reading about a pattern and being able to execute it live under interview pressure are different skills, and the practice bank exists specifically to close that gap.
