decent amount of DSA and System design were asked, and behavioral questions. so prepare leetcode level questions and good amount knowledge in sql, java and also mostly oracle sql. overall it was good
I applied through an employee referral. The process took 3 weeks. I interviewed at Oracle in Apr 2025
Interview
Stage 1: Initial Screening (HR/Recruiter),
Stage 2: First Technical Interview (Technical Staff Member)
Purpose: To evaluate your fundamental coding abilities, problem-solving skills, and understanding of core Java concepts. This interview will likely include a coding challenge focused on Strings (LeetCode Medium).
Java Core Concepts: The interviewer will likely ask questions to assess your understanding of fundamental Java principles:
Object-Oriented Programming (OOP): Encapsulation, Inheritance, Polymorphism, Abstraction. Be prepared to explain these concepts with examples.
Data Structures and Algorithms: Basic knowledge of common data structures (arrays, linked lists, hash maps, trees) and their time/space complexities. While the coding challenge focuses on strings, they might ask about the underlying data structures used to implement string operations.
First online assessment. Then 2 interview rounds + 1 hr round. This was during campus placement. In interviews they mainly asked about dsa, os concepts, logical questions and some system design questions also.
I applied through other source. I interviewed at Oracle (Seattle, WA)
Interview
i got a return offer from internship, and I had to do one additional technical interview because I was switching branch. He first asked me a OOP question, and then leetcode medium level question.
