To be even more complicated here, as the english (?) standard is to have a title after name (M.D., Ph.D., M.Sc. ...) we used to have a rather different sets of titles, that are in front of the name.
Usualy that was the M.D. title, "MUDr." in czech, which holds the Dr part inside (like MUDr. House for example, LOL). There we not many other titles, there were fro those with technical universities, who got Ing. title, that would translated as engineer, which is most puzzling, since it describes just anyone working in engeneering, not someone with a graduate degree (I think Dipl. Ing. is used instead in Germany).
So, after some 5 years of university studies (in a row, there were no bachelors then), you were either Ing. in the past or nothing (or "master" Mgr. nowadays in non-technicals). Not medical doctors, they had 6 year study (and they still have) after with they got their MUDr. title. Even though actually they are on the similar level as master students.
Before PhD adoption here, we have something called "small doctorate" which was kind of less than PhD now, required addition few yeras and a defense, and those got awarded different "Dr" titles depending on the topic, RNDr. was a "doctor" of Science (math, physics, biology,...), PhDr. "doctor of philosophy" (psychology, sociology,..), JUDr. a "doctor" of law. These were also in front of the name and were quite of highly regarded.
Then it was a "big doctorate" that was equivalent to PhD now, that have a special title CSc. (or further DrSc. meaning a candidate or doctor (again) of science (any science, not only the biology-math-physics kind of science)) after the name, in addition to some kind of "RNDr" of so in front of the name.
So in past, if you were a "PhD equivalent" doctor, you had some of these "..Dr" titles in front of your name anyway.
But after PhD adoption, CSc. titles could be of course used still, but only by past holders, no new CSc. are given, since it was replaced with universal PhD degree. But since PhD is in back, and you need to get masters degree first, most people (like me) are now Mgr. Some Name, Ph.D., (which would be equivalent RNDr. Some Name, CSc. earlier) and as I told earlier, many people don't know what the PhD at the back is, so they just ignore it. And for the Mgr. they often ignore it just as well, because that is some kind of new generic title, pfeew.. to bad living in a country where actually titles do matter
Often they don't know where to write it, if you have a "Title" in a web-form it's usually thought as the "in front of the name" title. So it's complicated.
(and to be even more complicated, it's still possible to get "small doctorates" like RNDr. now, but since they don't have a professional value as PhD does, people only go for it if they don't feel enough for the complete PhD, or the other common reason is to get rid of the front "universal" Mgr. title, (it replaces it) because RNDr. is still more regarded than "unknown" PhD by common people.. and my late grandmother was always saying "what is it Mgr.? (short for "magister", that's how we call "master's" here) The magisters work in the pharmacy!" (sadly as with engeneers, "magister" is a professional title of pharmacy workers, it's all funny )
So I only write PhD after my name for international professional correspondence (no title for non-professional), because no one knows what Mgr. is (and in english writing PhD replaces MSc anyway, it's both in the back),
and I write both in czech, but the first is often looked down on and the second often not understood.
And no, therefore it's not common to be written as "Dr." (and there is no such title, you just write your full titles), but you can be adressed as such in spoken lanuage.
And as I don't insist as much on my title(s), if you have one, people tend to call you by it.. I mean, OK company managers that come to sell us stuff, then.. fine.. in that case I correct them "well if you insist on the title..", but as of quite an importance for medical stuff, people are called by their titles even in a hospital.
I mean nothing is as bizzare as if you hear adressing "oh, good morning, mrs doctor" to an old lady laying unresponsive on intensive care psychiatric unit.. but what can you do in a country such gnawed into titles..
Ah, screw titles
