The Backend Interview Landscape
Your 8-Week Study Plan
A structured preparation plan is the difference between random practice and systematic improvement. This plan covers all backend interview topics with built-in flexibility for your target companies.
The 8-Week Framework
Eight weeks, ordered so each one depends on the last
Schema design, normalization, indexing, query optimization. 2-3 hours daily.
Isolation levels, ACID, CAP, and when a document or wide-column store beats a relational one. 2-3 hours daily.
REST conventions, gRPC, GraphQL, auth, rate limiting, idempotency. 2-3 hours daily.
Bounded contexts, sagas, CQRS, event-driven communication, circuit breakers. 2-3 hours daily.
The four-step framework, estimation, caching, load balancing, consistent hashing. Step up to 3-4 hours daily.
URL shortener, rate limiter, notification service, chat. Time yourself at 45 minutes each. 3-4 hours daily.
CAP in practice, Raft, concurrency patterns, SLOs and error budgets. 3-4 hours daily.
Full mock interviews out loud, then targeted review of whatever they exposed. This week is diagnostic, not new material. 3-4 hours daily.
Daily Schedule Template
For a 3-hour daily session:
30 min — Review yesterday's concepts (spaced repetition)
60 min — New material study (this course's lessons)
60 min — Practice (LeetCode SQL, system design sketching, or lab exercises)
30 min — Write notes / teach-back (explain the concept in your own words)
Company-Specific Adjustments
Targeting Google?
- Add 1 extra week of algorithm practice (insert between weeks 4 and 5)
- Focus on coding efficiency — Google expects optimal solutions
- Practice explaining algorithmic choices clearly
Targeting Amazon?
- Start writing STAR stories from week 1 (aim for 15+ stories)
- Map each story to 2-3 Leadership Principles
- Practice weaving LP answers into technical discussions
Targeting Meta?
- Practice the AI-assisted coding format (use Copilot/Cursor to simulate)
- Focus on multi-file code navigation and architectural decisions
- Emphasize trade-off discussions in every system design practice
Targeting Startups?
- Complete 1-2 take-home projects to build speed
- Practice pair programming with a friend or on Exponent Practice
- Prepare "why this startup" answers and demonstrate product thinking

Progress Tracking
Use this checklist to track your readiness:
- Can design a database schema and justify normalization decisions
- Can explain B-tree indexes and when to use composite indexes
- Can design a RESTful API with proper status codes, pagination, and auth
- Can explain Saga pattern vs. 2PC for distributed transactions
- Can solve a system design problem in 45 minutes using a structured framework
- Can explain CAP theorem with real-world examples (DynamoDB = AP, Spanner = CP)
- Can identify and fix race conditions in concurrent code
- Have 12+ STAR stories ready covering different behavioral themes
- Can explain salary expectations and negotiation strategy
Remember: Consistency beats intensity. 2-3 focused hours daily for 8 weeks beats 12-hour cramming sessions on weekends.
