I recently attended a workshop at a renowned research institute, to which you can participate only if you're invited by the organizers, who were rather well-known researchers.
I'm wondering if there's a point in including this information on my CV? On the one hand, it shows that some recognized people think well enough of me and my work to invite me to this type of event; on the other hand I'm afraid of appearing over-proud of a minor deal.
(For context, I'm a PhD student.)
If it is "prestigious" and on "invite" only basis, I will definitely add it. For a PhD student, I would add any conference papers you got (for now), you can always change your list of publications later on. Keep in mind that in some fields (computer science), conference papers are weighted much heavily than journal articles!
