Process
Took the initial programming technical interview as practice, despite not wanting the commute or the significant pay cut it would entail. The interviewer was professional, but if a company wants to ask questions like this without providing any interview prep, they should at least offer competitive pay.
Questions
A very difficult LeetCode "Medium" problem, combining graph/tree DFS and string parsing.
Debugging pseudocode for a Transformer block.
