Commonly Asked TCS Interview Questions

The specific questions you’ll be asked in a TCS interview depend on the role. However, certain questions tend to come up frequently across positions. Here’s an overview of the top questions candidates report being asked and how to prepare stand-out answers.

Tell Me About Yourself

This common opening interview question is an invitation to provide an overview of your background and experience most relevant to the role. Keep your answer to under five minutes. Focus on your:

• Degrees and education credentials
• Years of overall experience and in speciality areas
• Past positions, companies worked for and notable accomplishments
• Technical skills and expertise
• Reason for interest in TCS and the open position

You can use a “PAR” structure when responding:

P – Problem faced

A – Action you took

R – Results achieved

This technique helps craft compelling stories versus just reciting a factual resume summary.

Why Are You Interested in This Role?

With this question, interviewers want to gauge your passion for the opportunity. They are trying to determine if you just applied for the sake of having a job or if you are truly excited by and fit for the position.

Thoughtfully reflect on what draws you to the role and TCS before your interview. Make sure your answer conveys sincere interest and highlights relevant strengths. For example, you may say:

“I’m excited for the chance to take on more project management responsibilities and lead complex IT deployments from start to finish. TCS is doing innovative work modernizing infrastructure and applications through cloud and automation. I look forward to contributing my skills in Agile, AWS and DevOps to deliver robust solutions for clients.”

Why Do You Want to Work for TCS?

Along similar lines, interviewers want to know what attracts you specifically to TCS versus another tech services firm. They are listening for knowledge of the company’s offerings, values and culture.

Do your research before the interview so you can speak to specifics that appeal to you. Mention factors like:

• Global footprint and opportunity to work with multinational clients
• Commitment to diversity and inclusion
• Career development programs like Ignite My Future
• Cutting-edge services around digital transformation, automation and AI

Convey your alignment with TCS’ core mission and principles. Show that you want to work for them, not just take any position that comes along.

What Are Your Salary Expectations?

Questions about your desired salary can trip up candidates if not handled carefully. Try to avoid naming an exact figure unless required. Instead, say your salary expectations are open or flexible based on the total compensation package.

If pressed to share a number, give a reasonable range informed by research on TCS salaries for similar roles. Explain that you prioritize finding the right fit and are willing to negotiate fair compensation aligned to your experience and the position responsibilities.

Deflect back to learning more about the complete rewards programs at TCS including bonuses, retirement plans and other perks. Show you are focused on succeeding in the role more than the starting pay rate.

What Are Your Greatest Strengths?

This is your chance to highlight 2-3 qualities that make you a strong candidate for this job at TCS. Think about the key requirements and responsibilities of the role. Select strengths that best align to these and provide specific examples of when you demonstrated these traits.

For a technical position, for instance, you may share strengths around programming languages, systems integration or data analysis. Or for a consulting job, highlight analytical problem-solving, building trusted advisor relationships and communication skills.

What Are Your Greatest Weaknesses?

The weakness question is another potential landmine. Don’t actually share your core weaknesses or flaws. Rather, pick an area that is not critical to success in this role. Position it as a “growth area” you are actively improving versus a weakness.

For example, you could mention wanting to become more proficient in a technology that would be helpful but not mandatory for the position. Or share you are developing delegation skills as you transition from individual contributor to people manager roles.

Follow up the weakness by talking about the proactive actions you are taking to improve in this area. This way, you turn the question into a positive.

Why Should We Hire You?

This gives you a prime opportunity to sell yourself as the top candidate for the job. Summarize why your skills, experience and passion uniquely equip you to excel in the role and add value to the team or company.

Speak to concrete examples that illustrate strengths aligned to the position like:

• “I spearheaded the deployment of multiple cloud-based applications that boosted workforce productivity and customer satisfaction scores by 25%.”

• “I simplified coding processes that accelerated software releases from quarterly to weekly cycles.”

• “I overhauled supply chain operations, reducing costs by $2.3 million annually while improving part accuracy rates by 13%.”

Close by expressing your enthusiasm to bring your capabilities to TCS and reiterating your core motivations that make you a great cultural fit.

Do You Have Any Questions for Us?

Never say no! Use this as a chance to demonstrate thoughtful interest in the company and role. Ask smart, well-informed questions that show your preparation and align with your motivations for pursuing the position.

Good options include:

• Asking for more details about day-to-day responsibilities and challenges
• Inquiring about top priorities and goals the team or department is driving towards
• Requesting insights into the corporate culture and values
• Following up on key benefits, training or advancement opportunities

TCS Technical and Coding Interview Questions

For IT roles, expect your TCS interview to include assessments of your technical abilities. Be ready to tackle coding challenges, explain your approaches to projects and answer questions about systems, tools and platforms.

Review these examples so you can ace the tech portions:

Q: How would you go about debugging an application that is running slowly?

A: I would use profiling tools to isolate the slow parts of the code. Then I would analyze those sections to identify any inefficient algorithms, unnecessary steps or repetitive processes to optimize. I would also check that proper caching is implemented across the app. Beyond code issues, I would check for problems like insufficient memory, database call failures or network bottlenecks.

Q: How do you ensure quality and accuracy when developing an application?

A: I incorporate testing throughout the development cycle with unit testing for individual components and integration testing across connected systems. I also build in monitoring so any bugs that surface post-deployment can be swiftly tracked down. I leverage code reviews and collaborate with QA teams to identify defects early when they are easier to fix. I emphasize clear requirements gathering and documentation so the end application meets needs.

Q: Can you explain inheritance, abstraction, encapsulation and polymorphism in object-oriented design?

A: Inheritance allows new classes to be defined that reuse behaviors from existing classes. This helps reduce duplication. Abstraction focuses on the essential features of an object ignoring unnecessary details. Encapsulation bundles data and functions within a class and restricts direct access to prevent corruption. Polymorphism enables the same operation to act differently based on the data types it applies to. This flexibility makes code more easily extensible as needs change.

Q: How would you go about optimizing the performance of a web application?

A: I would speed page load times by minimizing code size, using compression, implementing caching and reducing server requests. I would optimize images and videos by choosing the right formats and compression levels. Using a content delivery network can improve load speeds by distributing resources geographically. I would also profile pages against performance best practices and fix any issues. Setting performance targets and monitoring helps sustain optimization.

Q: Please write a function to reverse a string recursively without using any loops

def reverse_string(input):  if len(input) == 0:    return ""  else:    return reverse_string(input[1:]) + input[0]

Being able to effectively respond to technical questions and code challenges will help demonstrate your hands-on abilities to the TCS hiring team.
