Applied through a school coop system. Interview went extremely well, it truly seemed that the person that interviewed me cared about what I would be able to learn during my coop term and about my motivations and goals. I was able to get the job, BUT after 3 WHOLE MONTHS during exams the company contacts me saying they will not accept any coop students due to "business reasons". I had other job opportunities, but I had to decline them for Groupby. Because they took away their job offer so late, I was not able to find a job through the school system anymore and had to find a non paid internship during the summer. ***DO NOT APPLY TO GROUPBY FOR INTERNSHIPS*** They will be happy to get rid of you if they have "business reasons"
