Interesting general “technical solutions” questions

In software engineering interviews, often there are questions other than coding. Career Cup is a good website for example questions. Below are just some of them:

– How would you go about reducing the load time of a page?

– What is an HTTP redirect? When/Why would it be used?

– How do you change file permissions in Unix/Linux?

– Explain what a shell is and how it works. How does it interact with the kernel? Explain how it relates to privileges, other processes, what happens when you execute a command, shell variables, and anything else.

– When a system “freezes,” why does it usually work to simply reboot?

– Following the previous question, say the system freezes because of disc write operation. How do you find out which program is trying to write which file?
