HelloFresh interview questions

Initial call with HR followed by a technical challenge. The goal was to compare the performance of different approaches for binary classification task, you were provided with a dataset that had to do some exploration and feature extraction and answer some questions about . The problem is that you only had 4 hours to complete the task, which is very little if you are trying to do anything more than training a baseline model and do some quick feature engineering. After submitting the assignment, the recruited contacted me a few days later saying that there were not going to move forward because they would have liked to see more from my submission. I think their expectations for how much one can get done in 4 hours is way off, especially when working with unfamiliar datasets.
