"You are welcome, bye!"

Translation: Szívesen, viszlát!

[szundi00]

Viszlát is the shorter form of viszontlátásra, it is not so formal. But when you want to be polite, use the longer form. People will be happy to hear that ;) When you say goodbye to your friends (or to younger people), use Szia (or sziasztok - plural) instead.

[MrtonPolgr]

I use viszlát with friends without much problem, not to mention half-formal situations of course (e.g. university lecturers of younger age)

In this case, why the word "kérem" is not correct?

[EstherCsur]

the reason kérem isn't correct is because if you turn it to English it means please

[RayRay71625]

How about szervusz and szervusztok. Its like saying ciao in Italian. It is understood by Austrians and Germans too.

[JimDoyle15]

Isn't "hallo" also a legitimate way of saying goodbye? I just got marked wrong for it but my parents in law use ot often - but my wife says its not really correct. I'm a little confused!

[MrtonPolgr]

I'm gonna assume you are talking about Hungarian.

Halló is how people set up a conversation on the phone, I don't think I've ever heard it used differently.

Helló is used, and there are indeed people who use it as a farewell as well (no matter how this use annoys me).

[josiahsprague]

What about "Nincs mit, szia"?

[MrtonPolgr]

It seems to me it's accepted. And really, why not
