SLK Software Software Developer Interview: Rounds, Questions and Preparation

What the job involves

As a Software Developer in Indian IT services, you will build, test, and maintain applications for clients across domains like banking, insurance, and manufacturing. Day to day work includes writing code from requirement documents, fixing bugs, participating in daily stand-ups, and coordinating with senior developers and client teams. Freshers typically start with structured training and then move to project-specific development or support work.

Role and Technical Knowledge

1. 1

   What is the difference between a class and an object in object-oriented programming?

   Explain that a class is a blueprint defining properties and methods, while an object is a specific instance created from that class. Give a simple example like a Car class and a specific car object.

2. 2

   Explain the software development life cycle (SDLC) phases you have studied.

   List requirements gathering, design, development, testing, deployment, and maintenance. Mention that in IT services, projects often follow Agile or Waterfall models depending on client needs.

3. 3

   How would you write a SQL query to find the second highest salary from an Employee table?

   Show a subquery approach using SELECT MAX(Salary) FROM Employee WHERE Salary < (SELECT MAX(Salary) FROM Employee). Mention that window functions like DENSE_RANK can also work.

4. 4

   What is the difference between a primary key and a foreign key in a database?

   A primary key uniquely identifies a record in a table and cannot be null. A foreign key links to a primary key in another table to enforce referential integrity.

Practical Scenarios and Problem Solving

1. 5

   You are given a bug report from a client but cannot reproduce the issue on your machine. What steps will you take?

   Talk about checking logs, replicating the client environment or data, asking for exact steps and screenshots, and involving a senior if needed. Show a systematic debugging approach.

2. 6

   How would you handle a situation where you are assigned a task using a technology you have never worked with before?

   Mention breaking the task into smaller parts, using official documentation and internal knowledge base, asking for help after initial research, and delivering incremental progress.

3. 7

   Explain how you would test a simple login feature you developed.

   Cover valid and invalid credentials, empty fields, SQL injection attempts, password masking, and session timeout. Mention both manual testing and writing basic unit tests.

4. 8

   If you find a mistake in your own code after submitting it for review, what will you do?

   Say you would immediately inform your reviewer or lead, fix the issue, and re-submit with a clear note. Emphasize transparency and learning from the mistake.

Behavioural and Teamwork Questions

1. 9

   Tell me about a time you worked in a team during your college project. What was your role?

   Use the STAR method: describe the situation, task, action, and result. Highlight your specific contribution and how you handled any disagreement or delay.

2. 10

   How do you handle feedback or criticism from a senior or professor?

   Show that you listen without being defensive, ask clarifying questions, and act on the feedback. Give a short example of improving your work after feedback.

3. 11

   Describe a situation where you had to meet a tight deadline. How did you manage it?

   Talk about prioritising tasks, breaking work into smaller chunks, communicating early if you needed help, and delivering on time. Avoid blaming others.

4. 12

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

   Mention exposure to multiple domains and technologies, client-facing experience, structured training, and the opportunity to learn quickly across projects.

HR and Company Fit Questions

1. 13

   Are you willing to relocate to any city in India or work in different shifts based on project needs?

   Be honest but positive. If you are flexible, state it clearly. If you have constraints, mention them politely and show willingness to adjust where possible.

2. 14

   What do you know about our company and why do you want to work here?

   Research the company's services, clients, and recent news. Connect your skills and career goals to the kind of projects the company delivers, without claiming specific inside knowledge.

3. 15

   Where do you see yourself in the next three years?

   Show realistic growth: gaining strong technical skills, contributing independently to projects, and possibly taking on small leadership or mentoring responsibilities. Avoid saying you want to leave for higher studies immediately.

4. 16

   Do you have any questions for us?

   Ask about the training program, typical project domains for freshers, or the technology stack used. Avoid asking only about salary or leave policy in the first interview.
