Recruiter reached out on LinkedIn, gave 2 week preparation time.

Phone Screening

Question 1 : https://leetcode.com/problems/zero-array-transformation-i/description/
Question 2 : https://leetcode.com/problems/zero-array-transformation-ii/description/

I was able to solve question 1 optimally on my own, and after getting a bit of a hint, I managed to solve question 2 as well. However, I made some mistakes regarding the time complexity. The following day, the recruiter reached out to inform me that I had cleared the round and mentioned that I need to work on improving my understanding of time complexity.
