Ericsson Software Engineer I interview questions

Interview was pleasant about an hour long. Interviewers were friendly and professional. Technical questions including a problem to solve at the end ( in any language). However interview was some time ago (November) and I haven't been updated on whether I'm proceeding further or if I was unsuccessful. I have asked the status and the only reply I got was that I would hear in December. Also had asked about format or needing to prepare for interview and had no reply. Interview was a good experience but communication outside of that has been lacking.
