Study Plan
Data Structures and Algorithms
Weeks 1-2: DSA fundamentals and practice (5-7 problems/week).
Weeks 1-2: Focus on Data Structures and Algorithms. Cover arrays, linked lists, trees, graphs, hash tables, heaps, sorting, searching, dynamic programming, and graph traversal algorithms. Practice implementing these and analyzing their time and space complexity. Aim for 5-7 problems per week.
System Design
Weeks 3-4: System Design principles and practice.
Weeks 3-4: Dive into System Design. Study concepts like scalability, availability, reliability, consistency, load balancing, caching strategies, database design (SQL vs. NoSQL), message queues, and API design. Review common system design interview questions and practice designing systems like Twitter feed, URL shortener, etc.
Behavioral and Soft Skills
Week 5: Behavioral questions (STAR method) and behavioral system design.
Week 5: Behavioral and Behavioral System Design. Prepare to discuss your past experiences using the STAR method. Think about leadership, teamwork, conflict resolution, and handling failures. Also, consider how behavioral aspects might influence system design choices (e.g., team collaboration on design).
Company Research & Mock Interviews
Week 6: Company research and mock interviews.
Week 6: Company Research and Mock Interviews. Understand Dataminr's mission, products, and technology. Conduct mock interviews with peers or mentors to simulate the actual interview environment and get feedback on both technical and behavioral aspects.
