Anyone offer some good interview questions?
I have moderate Linux experience myself, but must interview some candidates for some Linux Administration positions. I was wondering if anyone out there could offer up some good moderate to advanced Linux administration questions fit for an interview. I think I have all the basic ones I need. I am looking for either "right or wrong" questions, or scenarios. Accompanying answers would also be greatly appreciated, or at least, what you would look for in an answer.
Thanks All Geoff |

things in Linux/Unix are distro dependent ... as I learnt just the other week RH has even made extensions to useradd (the -r flag). Commands like tar are out there in several versions/flavours. How about giving a rough idea of the environment, and what the tasks in question would be? Or if asking for tasks is too specific, what are the machines the admin is going to look after doing?

I'm going out on a limb here since I see you have Red Hat listed and that is my distro of choice.
I would use mostly command line questions as any Windows user can figure out the click click thingys. For example... From the command: chkconfig --list iptables I see that level1 shows iptables as being off. This is a big security problem isn't it? Why or Why not? Answer: Not a problem as networking is off in level1 and you are not connected to any other machines. How do I determine the Linux version that I am using? Answer: uname -r Remember that Linux refers to the kernel How do I determine the Red Hat version that I am using? Answer: type the command cat /etc/redhat-release or browse to that directory and view the file directly. List two commands to find the hardware address of eth0 Answer:ifconfig eth0 and ip addr List the steps to create a partition using fdisk and format it as ext3 Check around on the forum and I bet you could find a lot of ideas. :) |

Then there's always the problem where someone who isn't that technical ends up using the pop quiz, and the candidate gives a perfectly correct answer that wasn't on the answer sheet. For example, the Linux kernel version could also be obtained from the top line of /var/log/boot.msg. And unless you have 30 interfaces, you can just as easily issue ifconfig without the eth0 argument to get the hardware address. The point is, there is more than one way to skin a cat. If I'm interviewing an experienced Linux sysadmin candidate, these are the questions I'm interested in: - What OSs have you supported? - What application environments did you support? - What level of troubleshooting/support did you provide to application programmers / DBAs? - What was your storage solution? - How did you manage OS patching? - What was your HA/DR strategy? This makes it an open format, and what you're looking for is someone who: - Has demonstrated skills comparable to what you're looking for. - Can critically assess the strengths and weaknesses of strategies employed at other sites, and can even offer improvements in your own site's current strategies. - Will honestly acknowledge areas of weakness in their own skill sets, and doesn't try to bullshit. Granted, I've only ever done it once, but it landed me a top candidate. |
OHH> Old post.
