Hey everyone, sharing my experience to give back posts from this community genuinely helped me during prep 🙌

🟢 Round 1 (R1) – DSA
Question Types:
Disjoint Set (Union-Find) based problem
Interval-based problem (merging / scheduling style)
Verdict: ✅ Passed

🟡 Round 2 (R2) – DSA + LLD Mix
This round felt like problem solving wrapped inside a design discussion.
Edge cases around overlaps and ordering
Efficient use of sorting + greedy logic
LLD-style Part:
Designed an Attendance Management System
Entities, APIs, and data flow discussion
Handling scenarios like multiple check-ins, late entries, etc.
More emphasis on logic correctness than heavy OOP theory
Verdict: ✅ Passed

🔵 Round 3 (R3) – HLD (System Design)
Focus:
Designing a scalable backend service which interacts with LIVE running applications.
APIs, databases, and scaling strategy
Handling failures & bottlenecks
Discussing design trade-offs
Verdict: ✅ Passed

🟣 Round 4 (Hiring Manager)

Focus:
Past project experience
Ownership & decision-making
Team fit and communication
No deep DSA/LLD/HLD grilling here
Verdict: 👍 Went well

Final Verdit - Selected
