Interview focus

System design and scalability are often emphasized more in US-based interviews.Candidates in India might face more questions on core Java/Python and data structures.Behavioral questions might be tailored to local work culture and team dynamics.

Common questions

  • How would you design a URL shortening service?
  • Explain the trade-offs between SQL and NoSQL databases.
  • Describe a challenging technical problem you solved and how you approached it.
  • How do you handle concurrency in your applications?
  • What are your thoughts on microservices architecture?

Tips

  • For US interviews, focus on explaining your design choices and trade-offs clearly.
  • For India interviews, ensure a strong grasp of fundamental programming concepts and algorithms.
  • Research common business challenges and cultural norms in the specific region.
