Interview preparation can take weeks or months. The HR department was very helpful, giving me three weeks to prepare. They provided interview preparation materials, videos, and useful links that aided my preparation.

Hard DSA questions: trees, graphs. Basically, you need optimistic ways to approach a solution. I am able to solve 2 out of 4 questions based on arrays, binary search trees, and one linked list question.

It went well, but there was no feedback from the recruiter or HR. They are not following up. I was asked for exact answers, not general ones. The interviewer wanted whatever information they knew.
