ABB Sales Engineer interview questions

I have applied as a Trainee. and they called me for a job interview and when i went to the meeting they apologized for the mistake that the HR have sent my mail to them as an experienced and looking for a job engineer. while i was applying for a Training at the employment fair at my university.

The interview went well and I wasn't stressed at all. I felt the interviewers tried to be friendly. Mostly asked about my background and the knowledge on the new role. The interview was set up with the HR. HR contacted me and set up a time.
