The interviews were not challenging but really time consuming. Mine were all on different days so I wasn't there for 7 hours or anything, but 1 hour on 3 different days.
It started off with a personality test to a short phone interview. This was just basics, asking you about what else you're applying for and to see what kind of employment you want with the company. After that, they schedule you for a computer test. It's actually really easy. Read the directions at first, calm down. I was really scared but after it started... It was beyond easy. If anything, just do it accurately and that's better than not finishing. The WPM test was easy, just practice online. As long as you're over a 20 WPM you're fine. You're immediately alerted if you pass or fail.
After the computer test, they scheduled me for another phone interview that they said would take 30 minutes. Mine took 15, and it was a more standard interview where they asked about my skills and how I would handle a situation. After that, I was scheduled for a roleplaying interview. Once again, it was actually really easy. You're able to take notes and place them "on hold" if you do need a few seconds, which I didn't need at all. Main point of this is to be friendly, get the job done, and upsell.
They told me that they'd contact all applicants by today to say who got the job and who will go forward in the interview process. I somehow didn't make it. I think it was my age more than anything since I feel like, and been told, that I excelled in all.
Honestly an easy interview process but it's so long. Considering that there was still more than this, I'm not sure if I'd try to apply again. Keep in mind that you aren't actually learning anything about the company, you're just doing a series of tests...
FYI, The other reviews on here scared me more than anything. My process was definitely pleasant. The only part I'm questioning is why I didn't go further. It feels like a mistake.
Good luck!
