DSA (core)
Arrays, hash maps, trees, graphs, dynamic programming; 100+ medium–hard problems. OA and Tech 1 are heavily DSA-based.
Complete preparation guide for Unacademy placement 2025-2026. Step-by-step study plan, topic-wise strategy, exam pattern analysis, and tips from selected candidates.
Unacademy placement is driven by an Online Assessment (OA) of 90 minutes (2–3 coding problems on HackerRank or similar) followed by two technical rounds, a managerial round, and HR. Success depends on strong DSA, system design for video streaming and CDN, and clear communication. This guide matches Unacademy’s actual exam pattern and hiring focus in India.
DSA (core)
Arrays, hash maps, trees, graphs, dynamic programming; 100+ medium–hard problems. OA and Tech 1 are heavily DSA-based.
System Design
Video streaming, CDN, learning platforms, scalability; design for 1M+ users. Critical for Tech 2.
Tech stack
Python/Java/JavaScript preferred; databases (SQL/NoSQL), APIs, microservices. Often discussed in project deep dives.
Behavioral
Impact, problem-solving, teamwork; STAR stories for managerial and HR.
| Week | Focus |
|---|---|
| 1–2 | Arrays, strings, hash maps, two-pointer; 2–3 problems/day. |
| 3 | Trees (traversals, BST), graphs (BFS/DFS, shortest path). |
| 4 | DP (1D/2D, knapsack, LIS); revise weak areas. |
| 5 | System design: streaming, CDN, load balancing, DB design; practice “design live class platform.” |
| 6 | Mock OA (90 min, 2–3 problems); timed coding. |
| 7–8 | Mock technical + system design; project and behavioral prep; research Unacademy products. |
Unacademy offers ₹12–18 LPA for freshers (total compensation). Senior roles (2–3 years) can reach ₹20–30 LPA. Strong DSA and system design preparation aligns with their bar and improves negotiation leverage.
