Terramar DMC interview questions

Well I had a nice first interview and was told by the manager I would be getting asked back for a second interview. She assured me that I would receive an email by the end of the week or the following Monday. Unfortunately, even after countless follow ups over email and Indeed (the original form of contact) I never received a communication back on scheduling a second interview. I never received any communication at all in fact. I found this rather disappointing and unprofessional, especially considering that we had a conversation on timely communication during my first interview.
