Question 1: Given a list of Integers, any nodes that have values previously occured in the list and return the reference the the new head of that list.
Question 2: A Graph problem related to social media and people connected online. The connection nodes were given and edges. This was a disjoint graph. We have to return the number of connected to a particular user.
E.g Here in below image H is connected to 2 nodes so if we query H we have to return 2 as answer.

Round 2: Technical Interview
The technical interview was conducted by two interviewers from ION Trading. We started with a brief introduction about myself, as prompted by the interviewers after they reviewed my resume.
1. LRU Cache Design: One of the interviewers began by explaining the concept of a cache. Although I was familiar with caching, I listened carefully as he detailed it. He then gave me a problem involving the Least Recently Used (LRU) cache, specifying that the and operations must be performed in O(1) time, while maintaining the LRU property.

The interviewer hinted at optimizing retrieval time, suggesting the use of a hash map. I proposed using a hash map to maintain addresses, combined with a doubly linked list for efficient management. This approach met the O(1) requirement, and I successfully explained the pseudocode.
2. Object-Oriented Programming (OOP) Concepts: The interviewers then shifted to questions about OOP concepts. They asked why OOP is important, and we discussed key principles like encapsulation, inheritance, and polymorphism real life use.
3. System Design (OOP focused): Uber Taxi Management System: Next, they asked me to design a class-based architecture for an Uber-like taxi management system. I outlined my approach, focusing on how classes would interact to manage drivers, riders, rides, and payments. The interviewers appreciated my design and the thought process behind it.
4. Programming Challenge: Zigzag Level Order Traversal: We returned to programming questions, and I was asked to implement a level order traversal of a binary tree. While I was writing the code, they asked me to modify it to perform a zigzag (spiral) traversal. I successfully made the adjustments to the code to handle zigzag traversal.

Round 3: Case Study

In this round, the interviewer opened a PDF document on his laptop and asked me to read a paragraph related to online and traditional education. After reading, he asked me a series of questions to gauge my analytical thinking and perspective on the topic.

1. What is better: online education or traditional education?
My Answer: I explained that it depends on the situation. For children aged 5-16, traditional education is generally better as it supports overall growth, including social and physical development. For those aged 16 and above, both online and traditional education have their merits. Online education can be more flexible, time-saving, and offer a better understanding through interactive content.

2. Why not online education for kids?
My Answer: I mentioned concerns such as health issues (like eye strain), growth problems due to reduced physical activity, potential for addiction to screens, and the lack of social interaction that can lead to feelings of isolation.

3. Will online education overtake traditional education?
My Response: I believe online education will not completely replace traditional education, but it will certainly impact and complement it. The two can coexist, each serving different needs and preferences.

4. If various online education platforms like Byju’s are failing or facing losses, what would you do as the CEO or management?
My Response: I suggested opening offline centers in collaboration with popular local teachers to create a hybrid learning model. This would combine the strengths of both online and offline education. Additionally, I would focus on reducing unnecessary spending and optimizing resource allocation to improve financial stability.

Conclusion:
In conclusion, I believe both online and traditional education have their places. The best approach may be a blended model that leverages the advantages of both to meet diverse learning needs.
