Tier 2 IT support questions/ your experience

[Superfreak04]

So, I have an interview coming up for a tier 2 IT support position. (Desktop support). I was going through an IT staffing company, and when they sent in my application for Tier 1 support, the company said I was overqualified. So with that being said, they bumped me up to tier 2 support. Not really sure how I'm over qualified since I only have 10 months experience in tier 1 help desk support, and a Bachelors degree with no certifications. But anyways, I'm a bit nervous.

With that being said, I'm calling out to anyone who is currently in this role, or has had experience with this type of roll.

I'm curious as to what type of questions would be asked in the interview for this role, as well as what common problems I may encounter in the work place. I know that I would be dealing with a lot of networking, as well as other tougher problems, but I'd like to hear people's personal experience.

As I've said, I only have experience in tier 1 support, which is super basic (ie. I have a virus, internet isn't working, keyboard isn't working, etc.)

Thanks!
