I went on-site for an in-person interview. The interview consisted of a pair programming challenge. I was allowed to use any language, tools, or libraries of my choice to solve the problem.

The interview lasted one hour. All staff I interacted with were friendly and helpful.

The interview followed a standard format, where an input was given and certain outputs were expected.

The inputs were presented in a file on the disk. As a JavaScript engineer, this was awkward, as JavaScript is rarely used to read/write directly to the hard drive.

Due to NDA, I cannot disclose the specifics of the question itself.
