First received a call from a recruiter. After a brief phone interview, I was called by the manager for a second phone interview. The next step was a series of interviews at the company office in Wayne, PA. These interviews consisted of meeting with 6 different people throughout the day. The whole process lasted about 4 hours. I was told that there were still some candidates that had to be interviewed, and they would be in touch within a week.Overall the people were pleasant, but I felt that it was very unprofessional for them to not return a call even after my follow-up.
