How does FollowUp decide which question is important to me? (if at all) I'm concerned about the level of access required for this app before I try it out (I am a Product Manager). Sounds like you'd be reading through all my emails

Thank you ska. This is pretty insightful, and actually makes sense. We will try to incorporate your suggestions as we create more challenges. We are also looking for more data scientists and developers in general to help us built these solu

We had to reduce the time limit on the test to handle the traffic. The intended test duration is 90-120mins. I have updated the test duration to 90mins now. There is indeed some feature engineering involved. The challenge in the test can in

If you are interested, we are looking for data scientists and developers in general from the community to help us built these solutions and provide us with honest feedback. We are also looking at building support for other Data Science role

Thank you for the feedback! - We are not automatically grading it. We have learned that in the past that trying to automatically grade candidates on such challenges biases their approach, which breaks the point of a good data science challe

Agreed. Data Science is a very broad term. The challenge is designed for Data Scientists. We are trying to target all experience levels as of now through a screening/take-home test that should take about 60-90mins at a stretch. Do you

ska, our aim with the challenge was to allow candidates to not be biased by a fixed outcome and try to solve the problem as they would solve any real data science problem. This meant we couldn't automatically score/rank a candidat

That is correct. We had to reduce the time duration to be able to handle the traffic. We recommend 90mins for this challenge. What do you think would the right amount of time for this problem?
