Start 3–4 months early with a fixed routine: build a one-page resume, practise quantitative aptitude, logical reasoning and verbal ability daily, master one programming language with basic DSA, and revise core subjects like OOPs, DBMS and OS for technical roles. Research every company visiting your campus — their test pattern, interview style and previous questions — and finish with a few mock interviews before the season begins. Consistency over months beats last-minute cramming.

Most companies mix aptitude questions (percentages, time-speed-distance, puzzles), technical questions from your resume and core subjects, and HR questions like "Tell me about yourself", strengths and weaknesses, and why you want to join that company. Service-based companies such as TCS, Infosys, Wipro, Accenture, Capgemini, Cognizant and Deloitte follow a similar pattern: online test, technical round, managerial round and HR round. Practising company-wise previous year campus placement questions is the fastest way to spot repeating patterns.

Off campus placement preparation demands more self-management: you apply to companies yourself through career portals, LinkedIn and referrals, so your resume must clear ATS screening without a placement cell's help. You also face varied exam patterns since each company runs its own drive, and no coordinator briefs you on shortlists or schedules. Building referrals from seniors and employees and tracking application deadlines becomes as important as technical preparation.

Infosys campus placement preparation should begin with the online test pattern — usually quantitative aptitude, logical reasoning, verbal ability and pseudo-code or coding questions — followed by the technical and HR interview rounds. Practise Infosys previous year questions, strengthen one programming language deeply, prepare your resume projects thoroughly, and rehearse your HR answers. A live mock interview modelled on Infosys rounds helps you handle pressure before the actual drive.

A campus placement preparation course is worth it only if it gives you structure you cannot create yourself — a scheduled syllabus, company-specific mock tests and interviews, and honest feedback on where you are losing marks. If you are self-disciplined, free resources plus peer practice can work well; if you struggle with interview confidence or don't know where you stand, a course or 1:1 mentorship with someone from the industry speeds up progress. Always check the mentor's background and reviews before paying.

The TCS interview process for freshers typically has four stages: an online assessment (aptitude, verbal and coding/programming logic depending on whether you applied for Ninja, Digital or Prime), followed by a technical interview, a managerial round and an HR round. Technical rounds focus on your resume projects, programming languages, OOPs, DBMS/SQL and sometimes simple DSA. HR rounds include questions like "Why TCS?" and discussions on relocation and shift flexibility, so know the exact pattern for your specific role.

The most frequently asked TCS interview questions for freshers include explaining your academic projects and internships, OOPs concepts like inheritance and polymorphism, basic SQL queries and DBMS topics, simple programs such as palindrome or string reversal, and HR questions like "Tell me about yourself", "Why TCS?", strengths and weaknesses, and willingness to relocate.
