The Recruiter contacted me via Linkedin, and after a brief chat of 30-40 mins, she suggested I should do a technical and business case test.
I worked during the holidays as the recruiter needed the results ASAP.
It was not a very interest problem to solve, and the dataset in which I did wad to work was code generated.
I tried my best to make sense of those datasets, and made a good presentation, but never received any feedback.
I had to get in touch with the recruiter myself after 3 weeks, and she confirm that I was not selected, but did not give me any feedback of why and what they were expecting.
I believe this company did not respect my dedication and time at all.
