SDE‑2 / SSE in India: what changes vs SDE‑1 (skills, scope, system design depth)

Quick definition (India market)

• SDE‑1: execution + basics (0–2 yrs)
• SDE‑2 / SSE: ownership + depth (2–5 yrs): you’re trusted to ship end‑to‑end and unblock others.

What actually changes from SDE‑1 → SDE‑2

1. Scope: not just tasks — you own outcomes (latency, reliability, correctness).
2. Debugging: reading unfamiliar code and tracing prod issues quickly.
3. Design: basic system design + data modeling + tradeoffs.
4. Collaboration: clearer PRs, docs, handoffs, stakeholder updates.

Skill checklist (2–5 yrs)

• Strong core language + testing (unit/integration) + CI habits
• Databases: indexes, transactions, query thinking
• APIs: pagination, idempotency, rate limiting (basics)
• Performance: profiling mindset, caching basics
• System design: requirements → components → bottlenecks → failure modes

How to prepare (simple 2‑week plan)

• Week 1: revise DSA patterns + build 1 strong project story
• Week 2: 6–8 system design prompts + behavioural stories (ownership, conflict, tradeoffs)
