- https://www.geeksforgeeks.org/print-right-view-binary-tree-2/amp/
- https://leetcode.com/problems/copy-list-with-random-pointer/
I was able to solve the first 2 problems without any help from the interviewer. The interviewer gave me some hints on 3rd problem. For all the problems interviewer asked me to give an efficient solution in terms of time as well as space complexity.
Round 3: Technical Interview 2
This interview was started with a general introduction followed by a little discussion on my past interns and projects. First, he asked me how would I design databases for a e-commerce websites like amazon. Then he followed up with 2 DSA problems. The questions are as follows :
