I remember over a decade ago interviewing at a bank and being asked how much experience I had with [insert list of systems] and integrating data specifically between two of those systems. I had never even heard of any of the systems on the list. Got home and Googled them, nothing. Called up a friend who worked there and he told me those were internal names for their systems, no one who did not work there would have any idea what they were, and he was shocked they were asking about them using their internal names during interviews. Oddly enough, one was just an Oracle data warehouse fed by Informatica ETL and generating Cognos reports, and I had experience with all of that technology, but answered "no" when asked if I had experience with "the Pulsar system".
