01 / 04Phase 01 of 04
Weeks 1-2: Advanced DSA practice (LeetCode Medium/Hard), Big O analysis.
Weeks 1-2: Focus on core computer science fundamentals, including advanced data structures (e.g., trees, graphs, heaps) and algorithms (e.g., dynamic programming, graph traversal). Practice coding problems on platforms like LeetCode, focusing on medium to hard difficulty. Review Big O notation for time and space complexity.
Phase 02 of 04
Weeks 3-4: System Design fundamentals, distributed systems, practice designing scalable systems.
Weeks 3-4: Immerse yourself in system design principles. Study distributed systems concepts, database design, caching strategies, load balancing, and message queues. Read case studies of large-scale systems. Practice designing systems like Twitter feeds, URL shorteners, or ride-sharing platforms.
Phase 03 of 04
Week 5: Behavioral questions, STAR method, leadership examples.
Week 5: Prepare for behavioral and leadership questions. Reflect on your career experiences and identify examples that showcase your problem-solving abilities, leadership potential, conflict resolution skills, and ability to mentor others. Use the STAR method to structure your answers.
Phase 04 of 04
Week 6: Company research, mock interviews, prepare questions.
Week 6: Research Bolt's technology stack, products, and recent news. Understand the company's mission and values. Prepare thoughtful questions to ask the interviewers. Conduct mock interviews to simulate the actual interview experience and get feedback.
