The process is pretty simple. Start off by applying for the position next they sent me an email yo take an assessment test that you take at home its about (45-1 hr) long if u passed the first test you are invited to take the 473 exam at a located of your choice and that test is also bout 1hr-1 1/2) long pretty simple questions BUT YOU ARE TIMED..... once I finished my test maybe 15 mins later if that I checked my emailed and I passed. About a week later I got an email to do a Background check & drug test they both have to been done with the 3days from the date they give you.. Once I completed both i then got another email invite to interview once you get the interview the rest is up to you and how well you do so pretty much sell your self if you know this is what you want to do. Interview was the easiest part they just ask you basic questions as any other interview they want to know about you and how you would be a great fit with the company after answering bout 8-10 questions my interviewer strongly recommended me for they job. In the same week got another email offering me the job I accepted of course now I'm just waiting for my start date.
