I just finished Visa Pre-Screen (General Coding Assessment), administered by CodeSignal.
A 70-minute home assignment of 4 questions in: Basic Coding, Implementation, Data Structures, and Problem Solving. I took it in Python, and the platform wasn't really comparable to work in, and there was no debugging option.
Interview questions [1]
Question 1
Create a function that simulates terminal cd (change directory) commands to determine the final path. It starts at the root (/) and processes each command in order:
"cd ": moves into the specified directory.
"cd ..": moves up one level (if not at root).
"cd .": does nothing (stay in the current directory).
"cd /": resets to root.
