✅ Round 1: Core Technical Interview
Focus Areas:
Core Java (OOP, Exception Handling, Collections, Multithreading)
Java 8 Features – Stream API, Lambda, Functional Interfaces
Spring Boot – Annotations, REST APIs, Spring Security, JPA
SQL/Database – Joins, Indexing, Optimization
Problem Solving – Coding or logic-based questions
Sample Questions:
Difference between HashMap and ConcurrentHashMap
How does Spring Boot auto-configuration work?
Write a code to find the first non-repeating character.
Explain how microservices communicate and handle failures.
✅ Round 2: Advanced/Architectural or Managerial Tech Round
Focused on:
Project architecture, responsibilities
Real-time problem-solving
System design basics (may be asked at 4+ years)
Best practices, version control, and debugging
Scenario-based questions: “How would you handle X in a microservices system?”
🔹 3. Managerial/HR Round
Behavioral + Project Discussion
Your role in the project, challenges faced
Strengths/Weaknesses
Interview questions [1]
Question 1
hey asked me to explain the entire flow of how a Spring Boot REST API handles a request from the controller to the database."
Why it stands out: Tests depth of understanding in real-world applications.
"They asked me to write Java code to remove duplicates from a list without using Set."
Why it stands out: Checks both logic and coding style.
"They asked how I would make a microservice secure using Spring Security with JWT."
Why it stands out: Shows knowledge of authentication, security—a key in real-time systems.
"They gave me a scenario where one service is down, and asked how to ensure the whole application doesn't fail."
Why it stands out: Tests real-time problem solving with fallback, circuit breakers, etc.
"They asked me to explain how a HashMap works internally in Java."
Why it stands out: A classic mid-level question that dives into data structure
First round was aptitude which have logical questions and second round was technical interview in which they have asked about sql and introduction.Based on skills they have asked me the questions
round 1 screening.
round 2 cpp concepts all including dsa concepts.
Initial screening over phone and later online interview. Asked all releant questions for cplus plus and had to know all th concepts.
thats all i have to say.
I applied online. I interviewed at Mphasis (Bengaluru)
Interview
The interview process was quite lengthy and somewhat unorganized. Initially, my interview was scheduled but got cancelled at the last minute. After multiple follow-ups, it was finally rescheduled for a 45-minute session.
The interview mainly focused on standard Java topics such as Collections, Streams, JVM Memory, and Spring Boot concepts like Actuator and configuration. The discussion went well, and I was able to answer almost all the questions confidently.
However, despite the interview going well, the final result was negative. What made the experience more frustrating was the delay in communication. The result was shared after nearly three weeks, and even after continuously following up for about two weeks, the HR team mentioned they still hadn’t received feedback from the interview panel. Overall, the process felt quite tedious and slow.
