Context: North-America, hot summer, urban park, networking party.
An international mid-size consulting company is inviting future graduates (Msc in E-business at a top tier school in the area) at a sort of garden party bbq in an urban park.
It's presented as an opportunity to network, not necessarily getting a job right there, but getting to know this not so well known company and think of it when it's time to apply for internships or jobs when students will graduate in around one year time.
I'd know how to dress for a bit more formal networking event, but in this unusual setting I'm at a loss: no indication in the invitation, no indication from the school's job service.
Could you suggest –or is there– a dress code for a professional bbq party meet and greet ? Is that kind of event different from a normal networking cocktail?
