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.
A former coworker of mine was basically pushed out of the company we worked for, despite having basically written most of the software stack. He started doing independent consultant work for the customers, as the company’s management was such a disaster that they were unable to support deployments. He operated under the company name “MMI”, which stood for “Me, Myself and I”. I’ve stolen this name to describe working for myself on more than one occasion.
