They are interviewing candidates for positions that are: 1) Not yet required 2) With no job description They just want you on the bench so when the time comes they'll call you

Met with HR staff for an hour remotely. HR was nearly 10 minutes late. They struggled to describe the role and didn't know basic information about it. They spoke in a rambling stream of consciousness style and gave generally unhelpful responses. Despite their talking at length in response to my questions, I somehow still managed to learn very little about the job or team it was a part of. Did not create much confidence that this was actually a legitimate company or position.
