6 Infosys Coding Questions

If you’re a budding programmer or an expert trying to bag a job at Infosys, you might have specific questions

To help you get all the answers, we’ve compiled this super guide.

Before that, what is Infosys all about?

Infosys is an Indian IT company that has been focusing on business consultation, outsourcing, technology and other industry-related functions. The headquarters of this huge company is located at Bangalore but there are plenty of branches all around India.

In fact, Infosys is the third big IT company in India and getting a job there is a dream come true.

That being said, you can get inside Infosys; however, the test is pretty challenging.

To help you navigate, we have provided some details about the Infosys recruitment process, preparation hacks and some coding questions to crack the Infosys test.

Let’s get ahead.

What is the Infosys recruitment process?

The recruitment process of Infosys is straightforward. After you apply for the job through their online portal or college placement, you must be prepared for three rounds,

  • Online Infosys test
  • Technical round
  • HR interview

As simple as that.

Remember, in the test and the technical round, you won’t be facing Infosys coding questions alone. There will be questions placed to assess your behavior as well as your other overall core features.

These questions will let the recruiters find out whether you are a suitable person for the company’s structure.

Apart from these basic details, you must know the eligibility criteria of Infosys as well. It is

  • At least 60% marks in both SSLC and HSC
  • Must have a degree in BE/B. Tech with 65% of CGPA
  • No arrears or re-attempts
  • Education gap must only be of two years.

Preparation Tips

When it comes to preparing for any test that matters, you will need to start as soon as possible. Never delay your practice or procrastinate because when it comes to programming, there is so much to learn, almost infinite.

Here are some general tips for implementing as you practice for the Infosys test

Know your basics strongly

Be it formulas, syntax, data structures and algorithms concepts, your hold on these topics must be top-notch. Every coding question will be based on DSA, so if you’re not confident with the basics, you will find it hard to crack the test. Some of the general topics that you can cover are,

  • Arrays
  • Binary trees
  • Dynamic programming
  • Graphs
  • Hash
  • Sorting
  • Linked Lists.

Apart from these, there is so much more to DSA to plan a study schedule and keep learning something new about DSA concepts each day.

Pick a Programming Language

One benefit of the Infosys test is during the coding assessment, the candidates can choose a programming language they want to use. For example, if you choose C++, you will be given only C++-based problems to compile

Hence, if you’re sure about C++ concepts, syntax and other features, you can seamlessly answer these questions and run the program.

Prepare at least two commonly used programming languages in-depth to have an option during the test. Don’t just learn about one programming language because in a case in the test, you find the problem hard, you can always have another option to rely on.

Practice using online tests and interviews

There are so many websites that are offering free timer-based mock tests for people to be benefited from. You can quickly attend one or two of those weekly to refresh and increase your coding skills. As these tests are score-based, you can see how much you’re capable of scoring and where you can focus more. Additionally, these test questions will also carry solutions with explanations from which you can learn.

6 Infosys Coding Questions to Practice

The below Infosys practice questions are handpicked from previous years’ test questions. These will give you an idea of what to expect in your test.

Explain loop statements.

For every given condition, a loop statement will keep executing continuously until the result is satisfied. This aspect is most common in the C++ language.

Differentiate C++ and Java

JAVA

C++

In Java, pointers, unions, and operator overloading are unsupported.

Pointers, unions and other similar structures can be used in this language.

Garbage collection support is present.

In C++ garbage collection support is null.

Works on all platforms.

C++ works on every platform as well.

Inheritance is possible, excluding multiple inheritances.

All sorts of inheritances are possible.

Explain Object-oriented programming

Object-oriented programming (OOP) is a computer coding approach that organizes software design on data or objects instead of just procedures and logic. An object is a data element with specific qualities and properties.

OOP concentrates on the objects that coders want to manipulate rather than the reasoning required. Applications that are big, complicated, and associated with the formation or upgrade are a suitable fit for this type of work. This contains both mobile apps and manufacturing and design software. For example, OOP may be used in manufacturing system simulation.

Explain a pointer

A pointer simply denotes that a variable carries another variable’s address. Compared to variables that save data, pointers usually save the addresses which can be used for future references.

What is a virtual function?

A virtual function is a member function that is specified in a base class and reinterpreted (overridden) by a subclass.

When you link to an object in the developed class object using a pointer, you can perform a virtual function. This will execute the developed class's version of the function.

Explain Polymorphism

Polymorphism permits us to perform the same function in multiple ways. Both polymorphism and morph are Greek terms. Poly signifies many, and morphs mean forms. Polymorphism refers to the diversity of forms.

Conclusion

Infosys tests will give you a mind blowing experience as they have a very keen look to pick the best candidate. With these tips and the Infosys coding questions, all you should do is some consistent practice to crack the exam. All the best to your upcoming interview coders!
