I had one track down the phone number for my employer, call here, and ask the secretary to speak with me while refusing to say what the reason was until he spoke with me.
Hasn't happened to me, but it's happened several times to a guy I work with. They always claim that they need help with some software issue, I guess to make it sound more plausible, though I have no idea why anyone outside the company would call us for software help.
Same thing here - on top he was talking in English (I'm German) and didn't even ask if I was in a good position to talk. Talk about awkwardness to my colleagues.
At another job I worked at, our team had some of the most well-known devs in the metropolitan area, and our office line received 5-10 calls a day from recruiters asking for one of the devs. We had a team rule: you answer with "Hello" only and don't give any information to the caller until they give you their name, company, and reason for calling. It didn't stop some people from calling us daily.
