1. Online MCQ Test The first round typically involves an online multiple-choice questionnaire (MCQ) covering fundamental concepts in computer science. The topics include programming languages, data structures, networking, operating systems, and microprocessors. This round tests theoretical knowledge and logical reasoning. Candidates must answer around 50 questions, and the difficulty level ranges from easy to moderate. Scoring well in this round is essential to qualify for the next stage. 2. Coding Assessment The second round is an online coding test that evaluates a candidate’s ability to write efficient and optimized code. This round typically consists of five sections, each with a unique problem, and lasts for about two hours. The problems require a solid understanding of algorithms, data structures, and problem-solving techniques. Candidates must demonstrate the ability to implement solutions efficiently within time constraints. Strong performance in this round significantly increases the chances of progressing to the technical interview. 3. Technical Interview The third round is a one-on-one technical interview, where the interviewer assesses the candidate’s coding skills, system design knowledge, and technical expertise. Topics covered in this round include: Object-Oriented Programming (OOP) principles Data Structures and Algorithms (DSA) Operating Systems (OS) concepts Networking fundamentals Database Management Systems (DBMS) The interviewer may also ask coding problems that require real-time problem-solving and optimization. In addition, candidates are expected to explain their thought process while solving problems. If the candidate has prior project experience, they may be asked to discuss their past work, technical decisions, and challenges faced. This round is crucial in determining the candidate’s ability to apply theoretical knowledge in practical scenarios.

1. Laptop Test (Online Coding + Aptitude) The first round was a laptop-based test that included coding questions and aptitude questions. Aptitude: Profit and Loss problems Coding Questions: Reverse a string Count/find vowels in a string Convert a string to uppercase Find duplicates in an array Binary conversion This round mainly tested basic programming logic and problem-solving skills. 2. Technical Round 1 This round lasted around 50 minutes and was mainly based on core concepts and the resume. Java / Core Java Questions included: What is JVM and how it works Exception handling in Java Threads in Java Collection Framework concepts Deep conceptual questions from Java basics Coding Questions Find non-repeating character in a string Find missing number from an array Anagram program SQL Basic SQL queries and concepts JavaScript Basic JavaScript questions Microservices What are Microservices and their purpose Most questions were asked based on technologies mentioned in the resume. 3. Technical Round 2 (CTO Round) The second technical round was taken by the CTO. Discussion Topics Self introduction Detailed discussion about projects Which data structures were used in the project and why Coding / Problem Solving Difficult star pattern coding Longest palindrome in a string String manipulation question: Example: Input: I love java Output: I eovl aavj Logical / Puzzle Questions Bridge Crossing Puzzle There are four people: A takes 1 minute B takes 2 minutes C takes 5 minutes D takes 10 minutes Find the minimum time for all to cross the bridge.
