Hexaware Digital Software Developer Interview: Rounds, Questions and Preparation

What the job involves

Software Developers in Indian IT services build, test, and maintain custom software for client projects across domains like BFSI, healthcare, and retail. They work in agile teams, translate requirements into code, fix defects, and support deployments, often rotating across technologies based on project needs.

Role and Technical Knowledge

1. 1

   Explain the difference between a process and a thread, and why it matters when writing multi-user business applications.

   Cover memory sharing, context switching, and how threads improve responsiveness in server-side apps while processes offer isolation.

2. 2

   How would you find the second highest salary from an Employee table using SQL?

   Show a subquery or window function approach, and mention handling ties or nulls in a real project.

3. 3

   What is the difference between abstract class and interface in Java, and when would you use each in a service layer?

   Explain inheritance vs contract, and give a practical example like payment gateways where multiple implementations share common logic.

4. 4

   Describe the software development life cycle phases you have used in a college project and how testing fit in.

   Walk through requirements, design, coding, testing, and deployment, and mention any bug tracking or version control tool you used.

Practical Scenarios

1. 5

   You are assigned to a legacy Java project with no documentation. How do you start understanding the codebase?

   Talk about running the app, tracing entry points, using debug logs, and writing small tests to map behavior before changing code.

2. 6

   A client reports that a report generation page is slow only during month-end. How do you debug it?

   Mention checking database query plans, indexing, batch sizes, and server logs, then proposing a fix like pagination or caching.

3. 7

   You need to add a new field to an existing database table used by a live application. What steps do you take?

   Cover backward-compatible schema changes, migration scripts, testing in staging, and coordinating release windows with the team.

4. 8

   Your code passes unit tests but fails in the client's UAT environment. How do you approach the difference?

   Compare configurations, data, and environment versions, and suggest replicating the UAT setup locally to isolate the issue.

Behavioural and Teamwork

1. 9

   Tell me about a time you had to learn a new technology quickly for a college project. How did you manage?

   Use STAR format: describe the need, your learning plan, resources used, and the outcome with a measurable result.

2. 10

   Describe a situation where your team disagreed on a technical approach. How was it resolved?

   Show listening, data-based reasoning, and willingness to accept the better solution, not just winning the argument.

3. 11

   How do you handle feedback on your code during a review?

   Emphasize openness, asking clarifying questions, and improving the code without taking it personally.

4. 12

   Give an example of a deadline you missed and what you learned.

   Be honest, focus on the lesson like better estimation or early communication, and how you applied it later.

HR and Company Fit

1. 13

   Why do you want to join the IT services sector rather than a product company?

   Highlight exposure to multiple domains, client interaction, structured training, and long-term growth in delivery roles.

2. 14

   Are you comfortable with relocation, rotational shifts, and working on any technology assigned by the project?

   Answer clearly with flexibility, and back it with a reason like eagerness to learn and adapt to business needs.

3. 15

   Where do you see yourself in three years in this role?

   Show realistic progression from developer to module lead, with focus on deepening technical and domain skills.

4. 16

   What do you know about our company's training and career path for freshers?

   Mention structured onboarding, certifications, and project allocation based on skills, and connect it to your own learning goals.
