I was initially selected for the Systems Engineer role during campus recruitment. Later, I got the opportunity to participate in an upgradation program conducted by Infosys, which evaluated candidates for the SP and DSE role. The upgradation program assessed our DSA knowledge, including problem-solving skills, coding ability, and core CS concepts. Those who cleared the evaluation were shortlisted for the DSE interview round. After around two months of being shortlisted, I attended my interview in Chennai. The interview was conducted in a single round and covered: 1. General Introduction – A brief self-introduction and discussion about my background. 2. Basic Programming Concepts – Core logic-building questions and syntax knowledge. 3. DSA Questions – Data Structures & Algorithms concepts, with a focus on problem-solving. 4. Coding Round in the Interview – Writing small to medium-level code snippets to solve given problems. 5. Basic Front-End Questions – HTML/CSS fundamentals and simple UI-related queries. 6. Database & SQL – Core queries, basic joins, and differences between common SQL commands. 7. Project Discussion – Detailed explanation of projects I had done, particularly those demonstrating coding and technical problem-solving skills. 8. Resume-Based Questions – Questions from my areas of interest and skills mentioned in the resume.

A couple of coding and sql questions. A nested sql query was asked. Some medium level questions from arrays, strings etc. Sql was mainly focused on joins. Learn about joins.
