I've recently been on the hiring side of DT support interviews so I'll shed some light. Be able to join a Workgroup, change a computer name, install a local/network printer, terminate an Ethernet cable, set a static IP address, Subnet, and Gateway and multiple DNS entries. Be able to explain "over the phone" how to adjust monitor resolution or fix internet connection. Scenarios: how would you deal with an upset customer who thinks they are right? A time you couldn't fix a problem on the spot? How would you complete a task you haven't done before?
Make sure you can do these tasks in both Windows XP and 7. Also know how to do them in recent versions of OS X. With OS X, make sure to know how to boot from a disc, how to copy, paste, move files & folders via Terminal...be familiar with basic Linux commands.
- Emphasize customer service in every scenario, question, or demonstration.
- Look your interviewer in the eye when they are asking you the next question.
- Ask what the day-to-day job is like.
- Ask what kind of training will be available to you.
- Ask about time off, benefits, upward movement, company culture. Ask about your interviewers hobbies (technical or not). Engage with them and get the interview in your court.
- If you are asked about a situation you have never personally dealt with, say that and then say what you think you would do, or give a similar example.
- If you are asked a technical question on an OS you aren't familiar with but know how to do it on another OS, explain that instead and try to tie it all together.
Feel free to ask any questions
