From my limited experience, they want devs. The initial phone screen is all sysadminy questions (e.g. what commands show you i/o usage?). The second screen is a coding interview. I'm a sysadmin who works in bash every day. The coding questions are mostly related to log parsing. My code interviewer didn't seem to even acknowledge that bash was a programming language and did not understand a simple grep and sort pipeline.
Edit: Sorry everyone! I totally got my LinkedIn and Google interviews mixed up. What I described above is my LinkedIn experience.
