I was contacted by an internal HR recruiter based on a previous contact with Facebook HR via linkedin. I was given an overview of the position by the HR recruiter and a basic set of weed-out questions to answer. After that I was scheduled for a phone interview with the technical interviewer. The technical interview consisted of some more detail about the job and two scripting tests in a shared collaborative environment and one obscure problem to solve. The first script was to check some number of hosts for a daemon and send email about the hosts that did not have the daemon running. The second was to take a very large list of hosts and see if any were missing by comparing it to a reference list. This really only requires a diff and the interviewer seemed baffled by that solution so he changed the problem to require generating the reference file also. The third question was about accessing files in a directory used as an NFS mount point that had an active mount on top of it. The interviewer explained that the position was an interface between development and operations to avoid difficult deployments due to assumptions one group makes about the others intentions so it would require experience with both development and operations.
