The interview began with a detailed discussion about one specific line on my resume, which lasted for the first 15 minutes. The interviewer asked questions like "pass by value vs pass by reference." This felt surprising and out of place, given the expectations for a senior-level role.

The first coding problem involved an N-ary tree. The task was to traverse the tree with edge weights and find the maximum leaf node weight. I had to select an appropriate data structure and algorithm to solve it.

The second problem revolved around a grid with RGB colors and blanks. The goal was to traverse the grid, grouping the cells by color, and determine the size of the largest color group.
