Software Developer Interview

You know the concepts. You’ve done the course. You’ve built a project or two. But when someone asks you to explain your code out loud, or reverse a linked list on a whiteboard, something goes blank. That’s not a knowledge problem; it’s a preparation problem. Most freshers prepare for interviews by reading. Interviews are won by practising. This guide walks you through every round of a software developer interview in India in 2026, exactly what each round tests, how to prepare for it specifically, and the mistakes that cost freshers the offer when they were otherwise ready. How the process works (2026): Product companies and GCCs may add a second technical round or managerial round. Total time from application to offer: typically 2–4 weeks. What the Interview Process Actually Looks Like at Indian IT Companies in 2026 Before you can prepare, you need to know what you’re preparing for. The process differs meaningfully depending on who is interviewing you, and a lot of freshers realise this too late. IT services companies: TCS, Infosys, Wipro These companies follow a reliable three-round process: Online Assessment, Technical Interview, and HR Round. The OA covers aptitude, logical reasoning, verbal ability, and, for some companies, a basic coding section. There is no negative marking in most OAs, but sectional cutoffs apply more to that in the next section. The technical interview covers DSA basics, OOP concepts, SQL, and your project. The HR round evaluates communication and cultural fit as formal pass/fail criteria, not a rubber stamp. Based on Glassdoor fresher interview experiences from 2025–26, the full process from application to offer runs about 2–3 weeks. Product companies and startups in Pune Companies like Persistent Systems and KPIT run fewer rounds but make each one harder. Expect two technical rounds and one HR round, with no aptitude test at all; you go straight to code. The first technical round typically includes one or two DSA problems followed by a deep dive into your project. The second goes into system design basics and culture fit questions embedded into the technical conversation. The bar is higher, but so is the pay and the learning curve. GCCs: JPMorgan India, Deutsche Bank Tech, Goldman Sachs India These are the hardest filters for freshers and deserve their own category entirely. The online assessment includes quantitative reasoning at a higher level, not just standard aptitude. Technical rounds have stricter DSA expectations and often include a culture-fit round specific to the parent company’s values. These roles pay two to three times what IT services pay at the fresher level, but the preparation timeline is longer. Budget three to four months of focused work if a GCC is your target. Interview preparation is only one part of the hiring journey.

Most freshers know the technical content well enough to pass the technical interview. They never reach it because they treated the OA as a warm-up. What the OA actually tests The three standard sections across most IT companies are quantitative aptitude (percentages, ratios, time-speed-distance, probability, this is basics, not CAT level), logical reasoning (series, coding-decoding, blood relations, seating arrangements), and verbal ability (reading comprehension, fill in the blanks, para-jumbles). TCS adds a pseudocode or coding section on top of these. Infosys does not include coding for L1 roles. Know which companies you’re targeting before you decide where to spend your preparation hours. How to prepare specifically Aptitude is not knowledge; it’s speed. You don’t pass the OA by knowing how to solve a percentage problem. You pass it by solving it in under 90 seconds, consistently, under time pressure. That comes from repetition, not from understanding the concept once. Practice 20–30 questions daily for four weeks. Use IndiaBix for aptitude and reasoning, and LeetCode easy problems for the coding section. The student who answers 60 questions in 90 minutes beats the student who spends 90 minutes on 40 questions perfectly because the scoring is based on total correct answers, not the quality of the best ones. The one mistake that eliminates good candidates Sectional cutoffs are the silent killer of OA performance. You can score 90% overall and fail because your verbal section was below the cutoff. This happens constantly with technical candidates who ace the coding section but haven’t touched verbal prep in months. Distribute your preparation time across all three sections from day one. Do not specialise. Every week, practice all three areas, even if reasoning comes more naturally to you than verbal. The OA does not care about your strongest section; it cares about your weakest. Round 2: The Technical Interview: What Interviewers Actually Look For The technical interview is the one most freshers think they’ve prepared for and the one most freshers are surprised by. Reading about DSA and actually explaining your approach while writing code on a whiteboard are two completely different experiences. Let’s break down what the interviewer is actually evaluating in each part of this round. The four areas every technical interview covers Data Structures and Algorithms sit at the centre of most fresher technical rounds. For IT services companies, the focus is on arrays, linked lists, stacks, queues, and basic sorting, not hard LeetCode mediums. For product companies, trees and basic graph traversal get added to the list. The key is not just solving the problem, but explaining your reasoning while you do it. Interviewers at companies like Persistent Systems and Wipro have confirmed in Naukri Campus fresher guides (2026) that candidates who think aloud while solving a problem consistently rate higher than those who solve
