Infosys is hiring 20,000 freshers in various fields and here is a complete guide to crack  this interview

1. Understand the Interview Structure

Infosys fresher recruitment usually has three main stages:

• Aptitude Test (Written Exam)
• Technical Interview
• HR Interview

2. Aptitude Test Preparation

The first stage typically includes questions on logical reasoning, quantitative aptitude, and verbal ability. Prepare the following:

• Quantitative Aptitude: Topics include time & work, percentages, profit & loss, probability, permutations & combinations, and number series.
• Logical Reasoning: Focus on puzzles, blood relations, data interpretation, and syllogisms.
• Verbal Ability: This includes reading comprehension, sentence correction, error spotting, synonyms/antonyms, and fill-in-the-blanks.

Resources:

• Books: RS Aggarwal’s Quantitative Aptitude for quantitative topics.
• Websites: Platforms like IndiaBix or Testbook provide practice questions.

Tips:

• Practice regularly under timed conditions.
• Use mock tests to improve speed and accuracy.
• Focus on weak areas after taking a few practice tests.

3. Technical Interview Preparation

In this round, Infosys assesses your understanding of basic programming, algorithms, data structures, and other core subjects. Here’s how to prepare:

• Programming Languages: Have a solid foundation in at least one programming language (C, C++, Java, Python).
• Data Structures & Algorithms: Study key topics like arrays, linked lists, stacks, queues, trees, and sorting algorithms.
• DBMS, Operating Systems & Networks: Be prepared for basic questions on SQL, normalization, joins, process management, and networking protocols.

Sample Questions:
• How would you reverse a string in your preferred language?
• Explain the difference between a stack and a queue.
• What is a deadlock, and how can it be avoided?

Resources:
• GeeksforGeeks and LeetCode for coding practice and theory.
• Books like Cracking the Coding Interview by Gayle Laakmann McDowell.

Tips:
• Focus on problem-solving skills and code optimization.
• Be ready to explain your approach in technical questions.

4. Coding Round (If applicable)
Some Infosys roles might require you to go through a coding round. Practice coding problems related to arrays, strings, recursion, dynamic programming, and greedy algorithms.

Tools:
• HackerRank, CodeChef, and Codeforces are good platforms to practice coding challenges.
• Focus on coding efficiency and edge case handling.

5. HR Interview Preparation
In the HR round, you will be evaluated on your personality, communication skills, and cultural fit. Common questions include:
• Tell me about yourself.

7. Common Mistakes to Avoid
• Lack of Practice: Not practicing enough aptitude or coding questions can lead to poor performance in tests.
• Unclear Communication: Even if you know the solution, being unable to explain it well in technical interviews can hurt your chances.
• Overlooking HR Round: Many candidates prepare for technical rounds and ignore HR. Remember, HR rounds can be just as important.

8. Key Resources
• Aptitude: RS Aggarwal for Quantitative Aptitude.
• Coding: HackerRank, LeetCode.
• Technical Knowledge: GeeksforGeeks for theory and coding questions.
• Mock Tests: Websites like IndiaBix provide Infosys-specific mock tests and previous year papers.

Hope this helps you 😊
