I had 2 separate interviews. The first interview was with the hiring supervisor and the second interview as with the hiring manager. In both cases, I was asked why I was interested in the job, what experience I could bring and my strengths/weaknesses. The hiring supervisor also questioned me about my willingness to travel and whether I had travelled internationally in previous jobs. In addition to the above questions, the hiring manager explained the group's training strategy and how I would fit into that strategy if I was offered and accepted the position.
I was interviewing as an existing employee for a lateral move. For new hires, I would offer the following advice. If you are an entry level applicant, be prepared to give an impromptu presentation on your resume. The purpose is to evaluate your communication skills. You will be asked situational questions and must draw upon your acedemic experience to answer as best as you can. Also be prepared to explain how you would solve a particular issue related to your field. The company is testing your problem solving abilities. New hires are typically interviewed by at least 3 people who meet afterwards to discuss the interviews and decide if you should be hired. If you are a mid-level applicant, be prepared to also answer situational questions but draw upon your professional experience to answer the questions. Your resume should highlight your professional accomplishments and any continuing education.
Willingness to relocate is a definate PLUS with this company.
