If you are called into an interview for HSI and TTM they will have a randomly selected floor supervisor come down and interview you. There will be a technical knowledge test. Don't fret though because there were a few people I knew there that failed all the questions (the test is pretty easy like what's a modem etc...) If you pass your drug test you will get the job.

I applied online, after a couple months I received a call about my application. I was asked if I had time to do a over the phone interview with generic questions such as "do you know what a modem is?" and "do you know what bandwidth is?" After the phone interview I was sent a link to take a test online that showed I was able to problem solve account issues and work quickly. After the online test I was told to call the original person, that did the phone interview, back because the training class started soon. She then checked the online test and set up an in-person interview. I showed up for the in person interview on time but had to wait a bit for the person that was interviewing me to come do it. The questions were generic and seemed like he wasn't prepared. After the interview he went to talk to someone from HR for about 15 minutes then said I'd receive a call to let me know the results. I didn't receive a call for about 2 weeks, when I did it was from another recruiter who had seen my resume. He asked me two generic questions and then offered me the job over the phone and I went in to do the paperwork that day. He mentioned to me that the original position I had interviewed for had been filled BEFORE I even went in to the original interview, but that I was qualified for the job opening he had now.
