You apply online and receive an email to read a script on voicemail. If they like the way you sound you will receive an email to set up a phone screening interview. During the phone screening interview you read a script and role play with the interviewer. After the interview if they like you they set a in-person interview where you get to go to the work site answer a few questions about yourself and shadow a team lead for about 5minutes.

Was sent an email after submitting my resume asking to call a number and read a script. A few days later got another email asking to schedule a phone interview. Read similar script on phone interview and was asked to set up face to face interview. At face to face interview first met with someone and was asked a few standard interview questions about previous experience and was told about the job. Listened to a few calls and met with another manager. Talked about the position and asked if it was something I think I could do. Was told would hear back the same day or following morning.
