Continu Customer Success Manager (CSM) interview questions

Interviewed at Continu about a year ago and I didn't have the experience they were looking for, which is totally fine. Applied for another CSM role that I definitely had the experience for about a year later. When I said I interviewed a year ago the conversation changed immediately, as if I wasn't allowed to apply again. They got back to me two days later saying the position had been filled. Yeah okay... so why'd you interview me then? I clearly threw them off when I said I had interviewed there in the past. Fast forward a couple months to now, which I saw another CSM role that caught my eye. I emailed them directly and received no response. I followed up with them once more and the next day I received an automated email that they won't be moving forward. Clearly Continu isn't interested in interviewing the same people twice, despite having the experience necessary. Kind of a shame actually, because if someone expresses interest in your company like that maybe it's a good thing, no?
