If you cannot solve PALINDROME in your coding interview, you will NOT get hired. Period. This is THE most asked string question in tech interviews. Google asks it. Amazon asks it. TCS asks it. Microsoft asks it. Infosys asks it. Every single tech company includes palindrome in their coding tests. And if you make ONE tiny mistake in your approach, interview over. In this video, I am teaching you how to check if a string is a palindrome using Java. Not just any method. The OPTIMAL method that interviewers want to see. The method that gets you hired. WHAT IS A PALINDROME? A palindrome is a word that reads the same forwards and backwards. MADAM is a palindrome. RACECAR is a palindrome. NOON is a palindrome. HELLO is NOT a palindrome. Simple concept. But coding it correctly? That is where most students fail. WHAT YOU WILL LEARN Complete algorithm explained step by step Live coding in Eclipse no slides just pure code How to compare strings from both ends Why you should NOT reverse entire string Time complexity O of n and space complexity O of 1 Common mistakes that get you rejected How to handle uppercase and lowercase Edge cases like single character and empty strings WHY THIS VIDEO IS DIFFERENT I am not using fancy tools or complicated explanations. I am coding in Eclipse 2016 style old school method just like you do. I make real mistakes and fix them in front of you. No editing. No hiding errors. Pure teaching. This is like sitting next to me and learning. You will understand not just the code but the LOGIC behind it. WHO SHOULD WATCH College students preparing for placements Job seekers appearing for coding interviews Anyone learning DSA in Java Students who failed interviews and want to improve Self learners building programming skills COMPANIES ASKING THIS TCS Digital, Infosys InfyTQ, Wipro Elite, Amazon OA, Google Campus, Microsoft Screening, Cognizant GenC, Accenture Off Campus, and literally every tech company. This question appears in 90% of string based coding tests. You WILL face this. The only question is are you ready? Watch this video. Code along with me. Test with MADAM, HELLO, RACECAR. Master this problem. Crack your interview. Source code in pinned comment. Subscribe for more interview questions. Drop your doubts in comments I reply to everyone. Your placement depends on this. Your salary depends on this. Your career depends on this.
