Apply online only, have a well rounded resume, and always try to be sure your application is seen.
This is how my Process played out ( i think)
Apply Online
Initial Phone Interview
In person Interview with Operations Manager
Drug Test
Final Interview With Operations Manager
Once I had the in-person interview, I was told pending everything else I would be hired.
Be professional, ask questions about how their office runs/benefits/hours.
After the initial phone interview about 30 days had passed. They said they would call me about setting up the in person interview. I called them back and they had forgotten. If I had never called, I would have never gotten the job!
