The interview process for a System Engineer at Infosys typically consists of multiple rounds, including an online assessment, technical interview, and HR interview. Here's a breakdown of the usual process: 1. Online Assessment (Aptitude + Technical) Aptitude Test: This is a standard part of the selection process and includes questions on: Logical reasoning Quantitative aptitude Verbal ability Data interpretation Technical Test: This part assesses your technical knowledge and problem-solving skills. You may be asked questions related to: Programming (often in languages like C, C++, Java, Python) Data structures (arrays, linked lists, stacks, queues, trees, etc.) Algorithms (sorting, searching, dynamic programming, etc.) Basic computer science concepts like operating systems, databases, and networking. 2. Technical Interview If you clear the online assessment, you will be shortlisted for a Technical Interview, which is usually conducted by a senior engineer or technical panel. In this round, you can expect: Core Technical Questions: Focus on your subject knowledge (based on your specialization, e.g., Computer Science, IT, Electrical Engineering, etc.). Topics could include: Data structures and algorithms Operating systems concepts (processes, threads, memory management, etc.) Networking fundamentals (TCP/IP, protocols, etc.) Object-oriented programming (OOP) concepts Problem-solving and coding exercises (usually with pen-and-paper or on an IDE) Practical Problem Solving: You may be asked to solve coding problems or logic-based questions live. For example, "Write a program to find the nth Fibonacci number" or "Implement a sorting algorithm." System Design (Optional): In some cases, depending on the role and experience, you might be asked basic system design questions, such as "Design a URL shortening service" or "Design a file storage system." 3. HR Interview If you perform well in the technical rounds, you'll be called for an HR Interview.
