I was interviewed on behalf of the interested employer. Interview started on time and took about 40-50 minutes.
1)Presentation of ISS and its services.
2)Classical "what can you tell us about yourself question", clarification questions on my CV
3) 20 minutes psychometric test (-0+).
Very professional and friendly interview. From they treat potential candidates I am sure they are good at what they do. I recommend ISS to employers and job seekers.
