A potential coworker of mine is from a Latin country, and has a full (?) name with 4 words. The first word sounds like a first(=given) name, the last word sounds like a last(=family) name. The middle two I'm not sure.
I remember several people from Latin countries (well, celebrities really) who had longer names they shortened, or use some other kind of short name. But - how am I supposed to address my coworker? That is, assuming I'm not as formal as using Mr./Ms. LastName? Should I just use the first word? The first two words? The whole thing?
Of course I could ask them, but it's a bit awkward and I'd like to start out with a reasonable default assumption.
