Ever wondered why interviewers are obsessed with Lists and Maps?
Why does O(1) time complexity feel like a magic trick in technical interviews?
Join us for an exclusive guest lecture by Mr. Rohit Kirtankar, Ads Solution Engineer at Google (Hyderabad), as he breaks down one of the most important foundations of coding interviews — data structures and time complexity.
This session goes beyond theory. Drawing from real-world industry experience and interview insights, the speaker will cover:
🔹 How Lists and Maps work behind the scenes
🔹 Why O(1) operations matter in real systems and interviews
🔹 How interviewers evaluate your choice of data structures
🔹 Techniques to structure and clearly explain answers during interviews
🔹 Common pitfalls candidates face — and how to avoid them
Through practical examples, interview-style problems, and optimization strategies, participants will learn how to think like an interviewer and respond like a strong candidate.
Whether you’re preparing for internships, placements, or product-based company interviews, this session will help you transform basic concepts into high-impact interview answers.
🚀 Perfect for:
CSE / AIML / IT students | Placement aspirants | Anyone preparing for technical interviews
