I was at a remote company last year and hiring (was lead, building the team) and right before one interview, I reviewed a resume and saw that there were.. 2 jobs for the same time period.

The best way to get the truth is to make all answers acceptable.

me: "So, job A was a 40 hour/week job, right?" him: "Yup" me: "But you were also doing work for job B then right." him: "Yeah, basically" me: "So you basically did job B whenever there was some slack for job A?" him: "exactly."

I was dumbstruck internally and then just wrapped up the interview politely and let him know a couple days later that it wasn't a good fit. No use alerting him that he should change his resume (for other possibile employers..)
