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)?
