Why These Interviews Are a Big Deal
Getting into a top IT company isn’t just about knowing how to code. Interviewers want to see how you think, communicate, and solve problems under pressure. These companies receive thousands of applications every month. Your preparation is what will make you stand out in that pile.
Your Step-by-Step Prep Plan
Think of this as your interview “survival kit.” Let’s break it down.
1. Brush Up on the Basics
Before you dive into advanced stuff, make sure you’ve got your fundamentals rock-solid:
Data Structures & Algorithms – Arrays, linked lists, stacks, queues, trees, graphs.
Computer Networks – OSI model, TCP/IP basics.
Operating Systems – Memory management, process scheduling.
Databases – SQL queries, normalization, indexing.
Object-Oriented Programming – Classes, inheritance, polymorphism.
Pro tip: Practice daily on platforms like LeetCode and HackerRank. Treat it like a workout—consistency matters more than intensity.
2. Code Like You Mean It
Set aside at least an hour or two each day for coding.
Solve both easy and tricky problems to stretch your skills.
Take part in timed contests to mimic real interview pressure.
While coding, explain your thought process aloud—this is a big plus in interviews.
3. Show Off With Projects
A resume full of projects says more than grades ever could.
Build a web app using React or Angular.
Try a small machine learning model with Python.
Deploy a cloud tool on AWS or Azure.
During your interview, be ready to explain not just what you built, but why and how. That’s where you win trust.
4. Do Your Homework on the Company
Before walking into the interview room (or logging into a video call):
Check the company’s tech stack on LinkedIn or Glassdoor.
Learn about their work culture and recent projects.
Prepare for behavioral questions using the STAR method (Situation, Task, Action, Result).
5. Polish Your Communication Skills
Even if your code is perfect, poor communication can cost you the job.
Practice explaining tech concepts in simple language.
Ask clarifying questions when needed (shows you’re thoughtful).
Avoid jargon when unnecessary—it’s about clarity, not complexity.
6. Don’t Skip System Design
For senior or mid-level roles, system design questions are common.
Learn how to design scalable systems like an online shop or a social media feed.
Use resources like Grokking the System Design Interview.
Focus on explaining trade-offs in your solutions.
7. Try Mock Interviews
Mock sessions prepare you for the real deal.
Partner with friends or join platforms like Pramp.
Request feedback immediately, and work on weak areas.
8. Nail the HR Round
Many candidates stumble here. Remember:
Be genuine—don’t try to be someone you’re not.
Prepare answers for common questions like “Why should we hire you?” or “Tell me about a challenge you faced.”
Show enthusiasm for the role and the company.
Mistakes You Should Avoid
Preparing generally instead of for the specific company and role.
Ignoring HR and behavioral interview rounds.
Leaving coding practice for the last minute.
Talking too little or too much in responses.
Resources to Keep Handy
LeetCode, GeeksforGeeks, HackerRank – Coding practice.
Glassdoor – Company reviews and interview patterns.
