I suppose I am in the minority but I thought it was a pretty good FizzBuzz challenge for DS.
In fact I'd say it is a bit aggressive for a 60 minute challenge.
Quite a bit of data wrangling is expected to complete modeling on all columns. Some regex knowledge would help here too (for example for wrangling internet_users column)
What was the idea behind asking for 20 most important features when we have 16 columns? Is it expected to do some feature engineering?
Disclaimer: I teach Python and basic Data Science to adults and I'd say most people would struggle to complete this in 60 minutes including myself.
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 indeed be solved in the most obvious way possible, as well as in the most creative fashion. We believe how a Data Scientist goes about solving the problem was more important than a fixed outcome.
