The interviewer asked me really difficult questions, and I could not answer them. The interviewer was too strict and was not responsive. It was the worst interview experience of my life. I didn't get the job, and I felt humiliated.

Medium level mostly DSA questions, ranging from LeetCode Medium to High difficulty. System design questions were also asked. Begin by designing the solution from its brute-force form to an optimal approach (as much as you can optimize).

I was asked two questions on DSA. The interview lasted one hour. They first asked me to introduce myself and then posed the following interview questions, which were based on greedy algorithms, stacks, and hash maps.
