I became a regular employee of the company I work for just this week, making me the newest in one sense.
I've been contracting for them since 2009, which would put me in the middle of the pack.
I started working for the company that merged into this one way back in 2003, and I'm the only one who used to work for that company still left, as well as having been at one or the other longer than most employees of the current company.
