Phone interview is the first step with an HR person, going thru your resume and experience, what do you do, salary expectations, etc. Afterwards HR will present your resume to the hiring manager who will choose which of the candidates they want to interview in person.

I went to job fare at bombardier wich was pretty big. My first interview over there they just looked at my general experience to know if i had good expertise. After talking for 2 to 5 minutes the person saw my cv and told ok its good thank put my cv aside. She told me dont worry you have good cv its good thing. So she classed me to get my real interview. My real interview where witt 2 managers, question where about what i can do and if i was willing to learn an other Erp program. They wanted to know if i did mass upload and why I changed fields to pricing to planning.
