I recently interviewed for the position of Project Engineer in the Full Stack Java domain at Wipro, and Iād like to share my experience to assist others preparing for a similar role.
Round 1: Online Aptitude and Technical Test
The first round was an online assessment that consisted of two sections:
- Aptitude: This section included basic logical reasoning, quantitative aptitude, and verbal ability questions. While the questions were fairly easy, they required quick thinking.
- Technical: The technical section featured Java-related multiple-choice questions, focusing on core concepts such as:
- OOP concepts
- Exception handling
- Multithreading
- Collections framework
- SQL queries
Additionally, there were questions covering front-end basics, including HTML, CSS, and JavaScript.
Round 2: Technical Interview
This round delved deeper into both back-end and front-end technologies. The interviewer began with questions on Java and gradually transitioned to full-stack concepts.
- Core Java:
- I explained OOP concepts with examples.
- I was tasked with implementing a real-world problem using Java classes.
- There were questions on Exception handling and Multithreading, where I was asked to write sample code for handling exceptions and creating a multithreaded application.
- Spring Framework:
- I discussed the Spring Boot lifecycle and annotations like @RestController, @Service, and @Autowired.
- I answered questions on creating REST APIs and their security measures.
- Database:
- I faced queries on SQL and Joins.
- I was given a scenario to design a database schema and write relevant queries.
- Front-end (JavaScript, React/Angular):
- Given the full-stack nature of the role, I answered questions on basic JavaScript functions and DOM manipulation.
- I also discussed React.js (since I had mentioned it in my resume), covering components, props, and state management.
- Problem Solving:
- I was given coding challenges related to string manipulation and data structures. One challenge involved reversing words in a string, while another focused on efficiently traversing a matrix.
Round 3: HR Interview
The final round concentrated on my soft skills, aspirations, and cultural fit. Some questions asked included:
- Tell me about a challenging project you worked on and how you resolved issues.
- Why do you want to join Wipro?
- How do you manage deadlines and handle pressure?
Key Takeaways
- Brush Up on Java Fundamentals: The interviewers expect a solid understanding of core Java concepts and their real-world applications.
- Grasp Spring Boot and Front-End Basics: Be well-versed in Spring Boot for back-end development and basic JavaScript/React for front-end tasks.
- Practice Coding Challenges: Focus on algorithms and data structures in your preparation.
- Prepare Project Examples: Be ready to share experiences from your past projects, particularly how you overcame challenges.
The entire process took about a week from the first round to the final offer. I was thrilled to receive an offer and am excited about this new opportunity.
I hope this information helps you in your preparation. Good luck!
