You will be asked to role play a scenario where the number of registrations for a service has dropped to 0 for the past 6 or so hours, setting off an alert. You will have to go through an incident response and elevation. You will be asked to write simple reports that are suitable for giving high-level status to a manager.
Coding test: Parse a (syslog) file to get various fields from the logs and message counts. Associate counts with the processes that logged them.
Describe how curl works. What happens when you call the command? Describe the process of loading libraries, parsing arguments, DNS resolution, etc.
