Mock Interview:
Interviewer said only 3 people have ever solved the first question after conducting hundreds of mock interviews. The problem was just presented with the number values and I was asked to solve for the next row of n. I was not able to code this fully because of how confusing the problem was. After reading the comments on leetcode for this problem and the acceptance rate I don't feel too bad about it.
Problem number 2 I was able to give the optimal solution with for loop and 2 counters and math.ciel solution and interviewer was happy. Interviewer then discussed how these questions have nothing to do with doing a software engineering job but because of how the job market is they have no choice.
