Crack MNC interviews, step by step
The rounds most IT companies run, what each one tests, and exactly how to prepare. Practise every round free in the portal.
Round 1: Online assessment: aptitude
Quantitative, logical and verbal questions under time pressure. Most service MNCs (TCS, Infosys, Wipro, Accenture, Cognizant, Capgemini) filter here first.
- Learn each company's pattern: sections, time per section and negative marking.
- Practise 45 minutes daily: percentages, ratios, time and work, speed and distance, probability, puzzles, reading comprehension.
- Time yourself: aim for about 1 minute per question and skip, then return.
- Review every wrong answer and write the shortcut in a notebook.
Round 2: Online assessment: coding
Usually 2-3 problems in 45-90 minutes, judged on hidden test cases.
- Pick one language (Python, Java or C++) and stay with it.
- Master arrays, strings, hashing, two pointers, sliding window, sorting, recursion, stacks and queues.
- Solve 2 easy and 1 medium problem daily; read the editorial when stuck for 30 minutes.
- Always test edge cases: empty input, one element, duplicates, negatives and large numbers.
Round 3: Technical interview
CS fundamentals, your projects and live coding. Interviewers check understanding, not memorised lines.
- Revise OOP, DBMS (normalisation, ACID, SQL joins), operating systems (process vs thread, deadlock) and networks (TCP/UDP, what happens when you open a URL).
- Prepare a 2-minute explanation of each project: problem, your role, stack, one challenge, result.
- Code aloud: restate the problem, give brute force, optimise, write clean code, dry-run, state complexity.
- Read the interview cards in the Arena: each has a step-by-step model answer.
Round 4: Managerial round
How you work with people, handle pressure and make decisions.
- Prepare 4 STAR stories: conflict, failure, leadership, tight deadline.
- Show ownership: what you did, what you learned, what you would do differently.
- Ask one thoughtful question about the team or role at the end.
Round 5: HR round
Communication, attitude, relocation, shifts and bond terms.
- Practise "Tell me about yourself" in 90 seconds: present, past, future.
- Answer strengths and weaknesses with real examples.
- Know the company: services, recent news and the role you applied for.
- Be honest about relocation, shifts and the service agreement.
Round 6: Resume and profile
Recruiters scan for 30 seconds. Make every line count.
- One page: skills, 2-3 projects with results, internship, certifications.
- Link GitHub (with READMEs) and a LinkedIn profile that matches your resume.
- Add verifiable certificates: employers can check Training Trains numbers on the Verify page.
A 30-day plan
- Days 1-10: aptitude basics daily + arrays, strings and hashing problems + OOP revision.
- Days 11-20: timed aptitude sets + stacks, queues, trees and sliding window + DBMS and SQL.
- Days 21-27: full mock tests every other day + OS and networks + project explanations aloud.
- Days 28-30: mock interview with a mentor, fix weak areas, polish resume and LinkedIn.
