Job title: easy, you can use your prev job or whatever your expertise is
Company: this one is tricky imo. I saw “Visitor” , “Personal Contractor”, “Freelance”, “Independent contractor”, and also made up name (Bob Inc)…etc.
Usually those places just want you to fill out the info online, then at the event, you scan a QR to get your badge. But in some rare case, they need to call out “Your name + Your company” to get the badges. What do you do? I had to use my prev company title and name.
I will often not mention my company in conversations, as it’s well-known and I don’t want anything I say or do associated with the company, just in case (risk management is a primary driver of the business).
So “Independent Contractor” is good enough, and vague enough.
