Ericsson Network Engineer interview questions

The first inteview was with HR manager. He asked questions to understand who you were. They asked about availability to travel abroad for a long time and to difficult countries as well (they could come up with examples, say Nigeria, Angola, Algeria, Lybia). A no is not a good answer... The it came the technical interview where they asked several questions to make sure you have a solid university background. No undergraduate would ever be considered for a job in this company nowadays
