I was hired from within--started as a CA and responded to a job posting in the breakroom. There was a brief phone interview, and then an interview at the office. They asked general questions about troubleshooting and CS skills and experience--nothing unexpected. Next, I had the chance to awkwardly be walked around the building and introduced to every person working that day.

The interview is fairly standard although you are expected to bring in a letter you have written about the CapTel phone addressed to a potential customer. Interviewers take questions directly from your resume, so be ready to answer how your past positions directly relate to Customer Service or working with either the deaf/hard of hearing or with seniors.
