Ericsson Senior Project Manager interview questions

The staffing agency called me and asked me if I am interested to work for Ericsson. I agreed and they submitted my CV to Ericsson. I was called again for a phone interview. I then received the call on per the appointment and lasted for about half hour. HR, the hiring manager and the function manager were on the call. They asked about my previous experience with Ericsson and how to handle stress and keep the customer satisfied. The interview was good and later I received an offer from the staffing company to start the job after doing a background check.
