TestEmployer interview questions

Coding Exercises: Solve problems live on a shared document or coding platform (e.g., HackerRank, Codility). Example: “Write a Java program to reverse a linked list.” Example: “How would you remove duplicates from an array using Java?” Conceptual Questions: Expect questions on core Java concepts like data structures, algorithms, exception handling, and concurrency. Example: “What is the difference between a HashMap and a TreeMap?” Example: “Explain the Java memory model and the garbage collection process.” OOP and Design Patterns: You might be asked to design a simple system or explain an existing design pattern. Example: “Explain the Singleton pattern and implement it in Java.” Example: “How would you design a payment processing system in Java?” System Design (Optional for Intermediate Roles): This could involve a simple system design problem, where you'd need to discuss how to build or scale a system. Example: “How would you design a URL shortening service like bit.ly?”
