Ghosted before first round of interviews

I applied to a Senior UX designer position with a pretty good company, heard back from the recruiter last Thursday and they wanted to schedule time this week to chat for the first round of interviews. The same day I heard from the recruiter, I added my availability online for our chat this week and...no confirmation. I reached out on Saturday to thank her and to say I was looking forward to our convo this week...no response.

I sent another email yesterday (Thursday) asking if it would help to add availability for next week and...nothing.

I understand this is the way it goes sometimes but left a pretty bad taste in my mouth.
