I first applied for StarTek on Careerbuilder.com. I passed the phone interview, and then I went for the on-site interview. Basically, when you are interviewing for StarTek, you need to exude several things:
1. Confidence, and a strong phone voice.
2. You need to be a fast typer. (50-60 WPM)
3. You need to show them that you will not show any sass or backtalk; no matter what happens to you.
