Preparation

How to prepare.

Tips

  1. Review fundamental data structures (arrays, linked lists, trees, graphs, hash maps) and algorithms (sorting, searching, dynamic programming, graph traversal).
  2. Practice coding problems on platforms like LeetCode, HackerRank, or AlgoExpert, focusing on medium to hard difficulty.
  3. Study system design principles, including scalability, availability, reliability, and common design patterns (e.g., load balancing, caching, database sharding).
  4. Prepare to discuss your past projects in detail, focusing on your contributions, technical challenges, and design decisions.
  5. Understand core computer science concepts such as operating systems, databases, and networking.
  6. Research eBay's products, services, and recent news to understand their business context.
  7. Prepare for behavioral questions by using the STAR method (Situation, Task, Action, Result) to structure your answers.
  8. Practice explaining your thought process clearly and concisely, both for coding and system design problems.

Data Structures and Algorithms

Weeks 1-2: Data Structures & Algorithms. Cover core DS&A, solve 5-7 problems per topic.

Weeks 1-2: Focus on Data Structures and Algorithms. Cover arrays, linked lists, stacks, queues, trees (binary trees, BSTs, AVL trees), heaps, hash tables, graphs. Implement common algorithms like sorting (quicksort, mergesort), searching (binary search), graph traversal (BFS, DFS), dynamic programming, and greedy algorithms. Solve 5-7 problems per data structure/algorithm type.

Questions

Commonly asked.

  • Design a URL shortening service like bit.ly.
  • Implement a function to reverse a linked list.
  • How would you design a system to handle real-time notifications for a social media platform?
  • Tell me about a time you disagreed with a team member. How did you handle it?
  • Explain the concept of eventual consistency.
  • Write a function to find the k-th smallest element in a binary search tree.
  • How do you approach debugging a complex distributed system?
  • Describe a situation where you had to make a difficult technical decision with incomplete information.
  • What are the trade-offs between monolithic and microservices architectures?

Interview focus

System design and scalability are often emphasized more in US-based interviews.Candidates in India might face more in-depth questions on data structures and algorithms.Behavioral questions might be tailored to local work culture and communication styles.

Common questions

  • How would you design a system to handle a large number of concurrent users for an e-commerce platform?
  • Describe a complex technical challenge you faced and how you overcame it.
  • Explain the trade-offs between different database technologies (SQL vs. NoSQL) for a specific use case.
  • How do you ensure the scalability and reliability of a distributed system?
  • Tell me about a time you had to mentor junior engineers. What was your approach?

Tips

  • For US interviews, focus on high-level system design and architectural patterns.
  • For India interviews, ensure a strong grasp of fundamental computer science concepts and coding proficiency.
  • Research eBay's specific product offerings and challenges relevant to the location.
