Toothio interview questions

Seemed like a good place to work and interviews went well. I was told I would hear back shortly for the next round, and then just ghosted. No rejection email, no communication, just nothing. Im not sure they were ever even hiring.

I had an initial video interview with the Director of Operations followed by another video interview several days later with the Co-founder. Sent each of them a thank you and follow-up email but never heard from their company again...GHOSTED. No response or rejection email sent. Only found out the role had been filled when I saw via LinkedIn that someone had started in the position. Unprofessional. Dodged a bullet.
