Optum Senior Recruiter interview questions

Applied via company page for a Recruiter role in Ireland. Received a message for a call. Spoke with a recruiter based in the UK on a Wednesday. She didn't seem to know a lot about the company and role as she stated she was part of a company recently acquired my Optum. Standard call that lasted 45 minutes where i did most of the talking. She stated she has a team call on Friday and will come back soon. This was 3 weeks ago and haven't heard anything since the call. Followed up twice with no acknowledgment of my messages at all. This is very very poor candidate management. I can understand why they are looking for new recruiters as this is not how you handle the recruitment process.
