Hi All,
I appeared for an interview at Oracle last week.
Experience: 5.5 years
Current Company: Service-based
Round 1: DSA + Technical Discussion (1.5 hrs)
- Problem-solving round involving the Longest Common Substring question
- Discussion on my project experience
- Concepts around memoization and lazy loading
- A few scenario-based questions
- Questions on design patterns
- React hooks fundamentals
- Core JavaScript topics were also covered
Round 2: Machine Coding + Deep Dive (1.5 hrs)
- Questions based on the technologies mentioned in my resume
- More discussion on design patterns
- Hands-on JavaScript coding (topics included higher-order functions, singleton pattern, closures)
- Questions related to the event loop
- Some output-based questions
- A few polyfill implementations
I haven't heard back after this round yet.
Note: A strong understanding of JavaScript fundamentals is also crucial for clearing these rounds.
Thank you!
