MetaLab Developer interview questions

Completely unprofessional. Interview lasted about 10 minutes, with the call dropping once. When I was asking questions about the company, the person interviewing me dropped completely (for the second time) and ended the call. They then proceeded to continue the interview through text and disregarded my question - only saying what the next steps were and apologizing for the "bad connection". Seriously, what kind of company doesn't have a working internet connection? What a joke. A day later I got a rejection letter with no reasoning.
