Wow is this common? I wouldn't be surprised. More and more, I see job posts that list multiple languages (more than two or three), and I wonder why they would have such a fragmented setup. But I guess having one script somewhere in Haskell, for example, might help attract a bunch of smart folks but who are then asked to write C# all day. There is a large informational gap between employees and employers unfortunately.
Happened to me twice, and Google once boasted about advertising for python to filter for devs at the forefront - not that they'd actually be doing much python. I guess one could check in the interview.
