Gartner Editor interview questions

I was contacted by a recruiter on LinkedIn. The role looked like a good fit and the initial video call went well. I was supposed to do an editing test the following Wednesday, and I'd receive the info about the test on Tuesday. By Wednesday morning, I hadn't received anything, so I checked in about the test -- no response. The time for the actual test came and went. I heard nothing back from the recruiter. They never followed up to explain what happened. Not wanting to engage with a company with this many red flags so early in the process, I did not email them again either.
