I was thinking it wants you to know what the output is for some given code.

As far as I can remember, yes. I graduated with a degree in EE in 2015 and considered trying to apply at SpaceX, but after hearing some anecdotal stories of long ruthless work hours decided against it. I don’t think his companies are well known for a great work life balance nor workers feeling like much other than another cog in the machine. They still did some great work though.
