<human>: I just had a phone interview with an old employer's HR department. At the end of the interview I was told that I should expect a call from the hiring manager to discuss, among other things, compensation.

The last time I was hired on at this company, which was four years ago and was my first foray into professional IT work, I was asked by the hiring manager what I believed adequate compensation for a full-time entry level Software QA job would be. I said $12/hr, but settled for $10/hr. (Truth being, my only other job offers were two fast food joints at $7.25/hr)

This time around, I have 4 years of IT experience (3 years doing full-time Sys Admin type work, working as a Lead IT Technician for a company that sells contracts for outsourced IT Administration), and 3 years towards a BS in IT, but no industry certifications to speak of (though I believe myself to be easily at an MCSA, A+, CCNA level, school and experience considered).

I'm in South East Michigan, I made $22.20 (+travel) at my last job, and I see similar positions advertising anywhere from $18/hr to $35/hr (full-time).

I'm not too familiar with this process, but presuming that the hiring manager asks me, again, what kind of compensation I believe would be commensurate to the position and my experience what do I say? $25/hr? $30/hr? $18/hr?

Give me the gist of the text in a nutshell
<bot>: 4y experience, 3y schooling, SE Michigan, PT Sys-Admin, what kind of pay do I want?
