I worked at Cbeyond (More than 5 years)
good company with employees and management
company was bought out by Birch Communication
I applied online. I interviewed at Cbeyond.
interview is not very technical however they will try to find out what you know in relation to job specs nothing to worry about as long as you have had IT exposure you should do fine. You have two interviews one face to face with upper management then sit with an Engineer interview once they decide they like you, your in just agree with everything they say.
