Preguntas de entrevista para el puesto de Senior Java/J2EE Developer en SiriusXM

Initial communication was through a recruiter who essentially set up a phone interview. I had a phone interview with the hiring manager and a few of his direct reports (apparently also developers). The questions were difficult and detailed for just a phone interview. Found the detail was extremely difficult to know what they were looking for however they stressed core Java skills especially. They also were very heavily interested in scalable, and concurrent development.
