The example in the post actually sounds quite relaxed (environment of candidate's choosing) compared to what I went through in a recent interview for something akin to a data analyst position.
I was given an Excel sheet with a mass of sales data in it and asked to come up with whatever 'insights' I could in 15 minutes. On a Spanish version of Windows/Office, running on a laptop with a Spanish localised keyboard layout (which meant none of the symbols were where I would expect them to be on a US or UK keyboard). I must've spent about 5ish minutes of the allotted time just figuring out how to get the required symbols to show up :(
