The Interview was conducted on phone and lasted for around 50 minutes.

Firstly the interviewer asked me about my Project which was based on Machine learning.
He asked me about the vanishing gradient problem and the difference between Supervised and Unsupervised learning.

He then shifted to Data Strcutures and Algorithms.

The questions asked were:

1: How will you code level wise traversal of Binary tree.

2: What is a heap? Explain Heapify and its applications.

3: What is a disjoint set and where it is used?

4: https://leetcode.com/problems/number-of-islands/

5: https://leetcode.com/problems/unique-paths-ii/

The interviewer wanted best solutions to the above questions and also why the following approach has been used?

Overall it was a nice experience and I was able to answer all the questions.

P:S : I got the offer next day.
