I noted that they had aggressive product deployment schedule (that one had little control over) that may required occasional OT or an weekend to get it out the door, that was fine and I understood it came with the nature of the work. I asked if they had a comp time i.e. work a Saturday and take a Monday off for example with mgt approval?

The quiz was pretty simple, you'll be asked basic questions about Linux. Battleship game: write a function that finds a ship and return its coordinates. Write a script that connects to 100 hosts, looks for a particular process and sends an email with a report. What is a filesystem, how does it work? File permissions, properties, file types. A write operation failed with an error, how do you figure out what happened? What's a signal and how is it handled by the kernel? What's a zombie process? Talk about an iostat output (what does user vs system cpu load mean, what does iowait% mean, cache vs buffers, why do we need caching, how much cache is needed, how can disk performance be improved, where is the bottleneck) How do TCP, UDP work? Describe what happens when a client opens a web page. How does DNS work? How does HTTP work? How does a router work? Various questions about your current experience, talk about a conflict situation and how you handled it. How would you design a system that manipulates content sent from a client (e.g. clean bad words in a comment post)? Write a function to sort a list of integers that looks like this [5,2,0,3,0,1,6,0] -> [1,2,3,5,6,0,0,0] in the most efficient way.
