The Poth road location is real hard to find. I drove by several times before finding it. It's actually in the Kroger warehouse. I didn't see the sign until actually parking in the Kroger lot and walking up to what I thought was the Kroger office to ask where EJA was.
Walking in without an invite worked for me. I'd suggest hand carrying your own app is a way to get it moved to the top of the stack.
Thanks for the info. I passed by Execjet last weekend. Unfortunately nobody was there. However, one of the security guards did take us on a tour of the facility. Pretty impressive. He said that he would pass on our resumes to HR on Monday. Hopefully the HR people will be impressed that we passed by.
