I have been trying to get in with one of the big grocery chains as an in-house tech/ coordinator of sorts. I am located dead in the middle of Knoxville and Chattanooga pretty close to I-75.
I have my vocational certificate and then some. School was free for me, so I took many classes beyond the scope of what I really needed. Heck, I even took Solar power classes.
I am respected by my contractors as being knowledgable and many of them call me for help when they are stumped. I am very experienced in controls for Parallel Refrigeration racks, including programming.
Now, if only one of those big companies in the are would answer my resume!
