Meta Software Developer interview questions

A series of phone interviews, final round is on main campus.

I was contacted by a recruiter for the security team through email about a few openings on the security team. I said, I would like to know more. After a number of email exchanges to set up a time, another recruiter emailed me and told me someone would call me at the scheduled time. The first recruiter mentioned that I will be using the tool on collabedit.com. So far, I was not told what position I was actually interviewing for or whether I was setting up a time for a general interview or whether they were giving me more details! I did apply to a few different roles on their site so I wasn't sure what was up. Turns out first phone call was with hiring manager and I was getting interviewed for a software engineer position. Hiring manager asked if I was told what positions were available and I said no and he was glad to explain for me. I told the manager I was hoping for a security engineering job, not software engineering. He told me I might be a better fit for a different team and he will tell the other manager I was interested and I will hear from him. I asked if there was a opening on that team and he said they are always hiring new talent. I took that as a good sign. I didn't actually get asked to code during the phone interview. I followed up with the recruiters asking where to proceed and whether I could interview with the manager on the other team and they said they will get back to me. I waited and got no emails setting up another interview. I asked what's going on and have not heard back. It's been 10 days. I guess I have been dropped? I am disappointed at the lack of communication and lack of detail from the recruiters. I guess this is common with big companies.
