SLB VOIP Engineer interview questions

Schlumberger interview 5/22/2014—three weeks waiting time with 4 person via conference number ID. Took approximately 55mins for the interview. Very detail voice interview. I manage to answer all questions using the knowledge that I had for many years supporting voice. Very knowledgeable managers and engineer. Sound like a very good team to work for if hired. Crossing my fingers because I like to retire with Schlumberger. The interview did not cover the role or what they hiring for. They said they putting the job on hold and could not find an exact person for the position. Please explain to the recruiters what you want please. Disappointed .
