The freelancers on the Worksuite platform go through a screening process. This process is designed around a profile screen, a video call, and a data science challenge. The challenges are built for areas such as NLP, Image Recognition, Time Series Forecasting, Classification, and Regression. For these last two, an applicant receives a train- and test dataset where the test dataset is not labeled. The applicant then implements their solution and returns the predicted labels from the accompanying test dataset. It is imperative that the dataset is either proprietary or can not be found online. Because in either situation the chance of fraud would be significant.
