Cracking a tech interview at a top product company (Amazon, Flipkart, Microsoft, or unicorn startups) requires more than just coding knowledge. The Indian hiring process typically involves an online assessment (OA), 2-3 technical rounds (Data Structures & Algorithms, System Design), and a final managerial/HR round. Each stage filters candidates ruthlessly. However, with the right preparation strategy, even non-IITians can secure offers of ?30 LPA+.
Platforms like HackerRank, CodeSignal, or Mettl. Usually 2-3 coding problems (medium-hard) plus MCQ on OS, DBMS, OOP. To excel, practice on LeetCode (top 150 problems) and GeeksforGeeks. Time management is critical � aim to solve within 70% of allotted time.
Focus on arrays, strings, hash maps, recursion, DP, trees, and graphs. Indian interviewers often ask variations of "Kadane's algorithm", "LRU cache", "merge intervals", and "lowest common ancestor". Use "think aloud" technique: explain your brute force, then optimise.
Design a URL shortener, WhatsApp, or a ride-hailing app. Understand load balancers, caching (Redis), databases (SQL vs NoSQL), message queues (Kafka), and microservices. Resources: "Grokking the System Design Interview", YouTube channels (Gaurav Sen, CodeKarle).
Behavioural questions using STAR (Situation, Task, Action, Result). Common themes: conflict resolution, failed project, leadership, learning new tech. Research the company's values. Have 5-6 strong stories ready.
Finally, mock interviews (with peers or platforms like Pramp, InterviewBit) reduce anxiety. With discipline, any motivated engineer can crack India's best tech jobs.
