Received a 30 minute interview over the phone. Was asked about 10 technical questions relating to TCP, VOIP, and a few other level 1 tech support related questions. The interviewer mentioned I did not have to answer all of the questions correctly and I would be notified at a later time if I would continue in the interviewing/hiring process. I never did receive a callback, I only received an automated email letting me know I was no longer being considered for the position. They did not provide a callback phone number and did not provide any feedback. The entire process lasted about 1 month.

Super bit of complex questions that might get you into the world of chaos and make you people hold onto grudge in them, so make sure you have someone in the company for referral and you can easily move on to the next steps.
