This was the first round, lasted around ~1.25 hours, began with me introducing myself and Interviewer explaining what their team does, in detail.

Q1. Implement queue using two stacks
- First told the simple way, then interviewer asked to optimize for pop operation in O(1) time, didn't care about push's time complexity.

Q2. Check if binary representation of a decimal number is palindrome (input is just a number in base 10 format)

Lastly some OOPS questions like what is polymorphism and it's types. What is copy constructor.

Overall pretty basic coding and OOPS questions
