Nagarro Interview Process
Nagarro interview process involves four rounds to effectively assess the core capabilities of a potential employee:
Written Test Round 1
This round comprises three major sections:
- General Aptitude Test: Mathematical and logical reasoning and verbal ability test.
- Technical Ability Test: Questions on operating systems, algorithms, data structures, programming languages, and networking-based problems.
- Coding Test: Three coding problems.
Written Test Round 2
The candidates who clear the first written round need to appear for a coding interview round. This written test consists of three to four coding interview questions. It is a paper pen-based round or could be held online via a test on HackerRank.
The interview round conducted at the company’s office requires candidates to optimize the code they wrote in the second written round. The interviewers put up questions on data structures, algorithms, and SQL. The questions can also be influenced by the technical skills mentioned on a candidate’s resume. Often puzzles are also a part of the Nagarro interview process.
The HR round involves behavioral and scenario-based questions. The recruiter inquires about a candidate’s goals and expectations from the job while assessing their soft and hard skills to determine if they fit the position and the company.

8. What is the merge sort, and how does it work?
The divide-and-conquer algorithm suitable for sorting the data is called merge sort. It merges and sorts adjacent data to create bigger sorted lists. These lists are then merged recursively to form even bigger sorted lists. The process continues until the programmer has one single sorted list.
9. What are dynamic data structures?
The collections of data in memory can expand and contract to shrink or grow in size as a program runs, enabling the programmer to control the amount of memory to be utilized. Examples of dynamic data structures are linked lists, stacks, queues, and heaps.

Encapsulation is the winding of data into a single unit/ class. Inheritance is an indication that a child class takes all the attributes/methods from a parent class.
11. What is concurrency, and why is it important in OS?
Concurrency or multithreading is the execution of multiple instruction sequences simultaneously. In operating systems, several process threads are running in parallel that communicate with each other via shared memory or message passing. It ensures:
- Faster and better performance of the OS
- Running of multiple applications
- Better resource utilization
- Better average response time
12. What is SQL injection? How can it be prevented?
SQL Injection is a code-based vulnerability allowing an attacker to access sensitive data from a database. Attackers often use SQL queries to add, modify, update, or delete records from a database. An SQL injection attack badly affects applications and websites using relational databases like Oracle, MySQL, or SQL Server. The following measures are effective against SQL Injections:
- Password hashing
- Object-relational mapping
