Study plan
Fig · Study plan — 05 phases
01 / 05Phase 01 of 05
Weeks 1-2: CS Fundamentals (Data Structures, Algorithms, OS, Databases).
Weeks 1-2: Focus on core computer science fundamentals, including data structures (trees, graphs, hash tables), algorithms (sorting, searching, dynamic programming), and complexity analysis (Big O notation). Review operating systems concepts (processes, threads, memory management) and database principles (SQL, NoSQL, ACID properties, CAP theorem).
Phase 02 of 05
Weeks 3-4: Distributed Systems & Microservices.
Weeks 3-4: Dive deep into distributed systems concepts. Study topics like consensus algorithms (Paxos, Raft), distributed transactions, message queues, caching strategies, load balancing, and fault tolerance. Understand microservices architecture, API design, and inter-service communication patterns.
Phase 03 of 05
Weeks 5-6: System Design Practice (Scalability, Availability, Performance).
Weeks 5-6: Concentrate on system design. Practice designing large-scale systems like social media feeds, URL shorteners, or real-time analytics platforms. Focus on identifying requirements, defining APIs, designing data models, choosing technologies, and addressing scalability, availability, and performance concerns. Study common design patterns and architectural styles.
Phase 04 of 05
Week 7: Behavioral & Leadership Prep (STAR Method, Company Values).
Week 7: Prepare for behavioral and leadership questions. Reflect on your past experiences and prepare specific examples using the STAR method that demonstrate leadership, problem-solving, teamwork, conflict resolution, and impact. Understand Sumo Logic's values and how your experiences align with them.
Phase 05 of 05
Week 8: Cloud, DevOps, and Sumo Logic Tech Stack.
Week 8: Focus on cloud technologies (AWS, Azure, GCP), containerization (Docker, Kubernetes), CI/CD pipelines, infrastructure as code (Terraform, Ansible), and monitoring/observability tools. Research Sumo Logic's specific technology stack and how their products are built and deployed.

System Design · 90 min · Principal Engineer / Architect
This round is a deep dive into system design. Candidates will be presented with a complex problem (e.g., designing a distributed caching system, a real-time notification service, or a large-scale data processing pipeline) and are expected to design a robust, scalable, and maintainable solution. The focus is on architectural choices, trade-offs, data modeling, API design, and handling non-functional requirements.
