LP part:

1. Tell me about the most significant technical challenge. How did you resolve it?
2. Tell me about the case, when you simplified a complicated solution? How did you simplify? Why was the first version over-complicated?

Tech part:
The question was a modified version of https://leetcode.com/problems/two-sum/
But instead of "return indices of the two numbers" there was requirement "return earliest indices of the two numbers".
