Infosys: Who It Is, What It Does, and How to Prepare for an Interview

Infosys is a global consulting and IT services company that employs hundreds of thousands of professionals. If you are considering a position at Infosys, practicing your answers to common interview questions can help you brush up on your knowledge and feel more confident during each stage of the hiring process. 

Having a little background on the company and what it does may also give you an edge and help you better prepare for your interview. While questions may vary, consider how you might answer some commonly asked questions in interviews with companies like Infosys. 

What is Infosys? 

Infosys is an Indian global consulting and IT solutions corporation based in Bangalore, India. Professionals at Infosys strive to consult with clients to provide helpful, technical business solutions. 

In just 40 years, Infosys has become recognised as one of the world’s most ethical companies and is one of the fastest-growing global IT service companies. Employing more than 345,000 people, this multi-billion dollar corporation has helped clients solve their business concerns and created some of India’s first salaried millionaires through their employee stock programme [1]. 

What does the Infosys recruitment process look like? 

Infosys’ recruitment process has three steps. It starts with an online assessment, then moves to a technical interview, culminating in an interview with human resources (HR). 

Online assessment: This test asks participants to answer questions in three categories to test verbal abilities, logical and analytical reasoning skills, and quantitative abilities. You might face questions regarding data sufficiency or interpretation, visual reasoning, statement reasoning, syllogism, analogy, coding-decoding, and related topics.

Technical interview: Once you pass the online assessment, you will begin the technical interview stage. Here, you may face many questions about your resume and areas of interest. Interviewers may ask questions during this round to gauge your knowledge of computer skills, programming languages, data structures, and analytics or to see how you problem-solve through puzzles and aptitude questions. Expect to also delve into your previous work experience during this round. 

HR interview: During this last step, you will face a broad range of questions from the human resources department. Expect to face questions about your life, education, hobbies, and views. This third and final round lets Infosys see if you’d be a good fit for the company. Interviewers may ask company-specific questions, and you should expect to expand on why you applied for and want the job. Sincerity and genuineness can only help you in this round, and you may consider going a step further to prepare by researching Infosys to see how you’d best fit in. 

10 Potential Infosys technical interview questions 

1. Explain Java's four major OOP (Object Oriented Programming) concepts. 

What they’re really asking: Interviewers want to ensure that you understand the basic concepts necessary to complete the job. 

When interviewers ask a question like this, it’s essential you know how to define the following terms: 

• Inheritance: Moving existing properties into a new class—the new class is called a “subclass” while the existing class is called the “base class.”

• Polymorphism: An object’s ability to take multiple forms 

• Data encapsulation: The practice of combining methods and data into a single class unit 

• Data abstraction: Representing a data set’s essential features while excluding the background details 

Similar questions: 

• Explain the difference between data encapsulation and data abstraction. 

• What is __, and how have you used it in your work? 

2. What is an object versus a class in OOPs?

What they’re really asking: Can you explain the intricacies of these terms and appropriately define them? 

If interviewers ask a question such as this, remember that, as an instance or member of a class, an object is responsible for physical operations, properties, behaviours, and individual attributes. A class, on the other hand, provides an outline for the object based on user definition. A class defines the object's properties, describes its behavior, and can exist without an Object. An object is a subset of a class and can’t exist without it. 

Similar questions: 

• How do you observe and use objects and classes in your day-to-day work? 

• Can you explain ___? 

3. What is stored procedure?

What they’re really asking: Do you have knowledge about stored procedures and how they fit into database management? 

A stored procedure is a group of statements unified by logic that can access an RDBMS (Relational Database Management System). It is stored in a database's data dictionary and is often used for data validation, but it can also be used for access-control mechanisms. 

First, let the interviewer know that you can properly define the term. Then, describe a specific experience you have with using, in this case, stored procedure. This will let the interviewer know that you know the term and have a specific and memorable experience with it. 

Similar questions: 

• Tell me about your experience with stored procedure. 

• How have you used the stored procedure? 

4. What is a frame in HTML?

What they’re really asking: How advanced is your knowledge and skill level? 

Frames allow authors to view HTML documents differently or present multiple documents simultaneously. You can use frames to divide browser windows into multiple sections, allowing you to load and present multiple HTML documents simultaneously. Like stored procedures, this is a perfect opportunity to demonstrate your knowledge and ability level regarding a specific skill. 

Similar questions: 

• Can you define ___? 

• Tell me about your HTML frames experience.

• Describe the benefits you’ve experienced while using HTML frames. 

5. Explain different levels of programming languages.

What they’re really asking: How much do you know about programming? What’s your ability level? 

Several levels of computer programming languages may be important for you to know: 

• Low level: This language is directly understood by a machine. Typically, humans do not code with this language.

• Assembly level: Similar to computer machine code, assembly-level language uses words instead of numbers to convey mnemonics, reducing complexity. 

• Middle level: Working to combine high-level and machine-level language, middle-level language interacts directly with a computer’s abstraction layer. 

• High level: As a human-understood form, high-level language does not require knowledge of computer hardware. 

This is a great time to show your proficiency with a specific skill. Chances are, a potential employer will ask a question like this about an important workplace tool. Use this to your advantage. Take time to discuss your ability level and then dive into an example or two to demonstrate how you’ve mastered certain skills and overcome challenges. 

Similar questions: 

• Tell me about your experience working with specific programming languages. 

• How have you improved your knowledge of computer programming? 

6. What is software development life-cycle?

What they’re really asking: Do you understand how to increase the longevity of this work? Are you knowledgeable on this specific subject? 

Software development life-cycle (SDLC) is a process that allows computer program developers to produce high-quality, low-cost software in a short period. SDLE can show a software’s methodology for complete development, maintenance, required analysis, and much more. 

A potential employer in this field may want to know how you plan to produce work quickly and cost-effectively. Knowledge about SDLC would be very beneficial in this case.

• What tools have you used in software development? 

7. Differentiate between DDL and DML commands in SQL.

What they’re really saying: This is an important skill in our workplace—are you familiar with it? 

For reference, here are the differences between DDL and DML: 

DDL (Data Definition Language): Without any further classifications, you can use DDL to define certain constraints and database schema using commands like CREATE, COMMENT, RENAME, etc. 

DML (Data Manipulation Language): DML is classified as either procedural or non-procedural. You use DML to manipulate existing data in a database using commands like DELETE, UPDATE, etc. 

This is another opportunity to demonstrate your skills and knowledge of workplace proceedings. Employers want to know that a potential new hire is at least familiar with workplace policies and tools, so don’t hesitate to expand on your personal experiences with a question like this. 

Similar questions: 

• Are you familiar with ___? 

• How have you used DDL and DML in SQL? 

• Our workplace frequently uses ___. Are you familiar with this? 

8. List some advantages of DBMS (Database Management Systems).

What they’re really asking: Do you believe this work has advantages? Do you understand what this work does for others? 

A DBMS controls and organises the structured information a computer system stores. Combined with software applications, DBMS provides users with an interface to update and manage data. It also allows users to create and maintain databases and links the user and their application to databases. Here are the main advantages: 

• Better data security 

• Improved data integration and access 

• Less data inconsistency 

• Improved overall simplicity 

• Assured recovery and backup 

• Increased user productivity 

This is where you can demonstrate a broader understanding of database management systems and discuss how this tool fits in a larger context. For a question like this, you’ll want to draw from personal experience alongside demonstrating an understanding of DBMS's specific qualities. 

Similar questions: 

• How is this work advantageous? 

• Where do you draw inspiration? 

9. What inspires you in this line of work? 

What they’re really asking: Do you want to do this? Are you passionate and committed? 

A question like this is a perfect opportunity to demonstrate enthusiasm for the position you’re applying for. Employers want to know you are knowledgeable and hard-working but also want to see passion and excitement! When answering this question, draw on specific experiences or memories to show that you’ve learned and grown from your previous positions. 

Employers want to know that you are flexible and willing to learn; knowing that a candidate is passionate and inspired by their work will leave a positive impression. 

Similar questions: 

• How do you hope to grow/progress? 

• What inspires you? Your work? 

10. Demonstrate ___. 

What they’re really asking: Are you the right person for this job? 

When applying for any position that demands technological proficiency, you may need to demonstrate certain skills, knowledge, or abilities during an interview. Specifically, regarding Infosys, interviewers may ask you to demonstrate knowledge of a coding language or use a specific application for a given task. They may require you to define specific terms and explain how they apply to the job you’re applying for. You might also need to compare and contrast different commands, coding languages, applications, etc.
