I applied through a recruiter. The process took 1 day. I interviewed at Quasus (Brussels)
Interview
2 cases were presented which the candidate had to solve. Questions are testing related ofcourse
Candidate also has to present himself.
If needed, the candidate will be invited for a second interview. this interview can be done the same day if the other person is available.
After that, the candidate gets a job offer if his application was successful.
Interview questions [1]
Question 1
Questions vary from person to person and from application to application. But, as far as I could compare, it seems that they are all logical questions
