I'm a data scientist (for an MLB team that will win the WS this year!) and I love this. Of course this isn't a whole end to end evaluation platform. But we will get 300-500…

Isn't the most important part weeding out the most unqualified applicants? For that purpose such a test might be fine.

I think this is good as a way to filter people out, but not as a way to rank people to find the best. I would want to see a short script to clean and predict a dataset, plus a…

I think this is great as a self-assessment tool, especially for beginners. It would work great with other learning tools, like MOOCs, datacamp, dataquest.io, as part of an…

What you're asking for looks a lot like a kaggle challenge. You're asking if someone can use xgboost (or linear regression). It's the last ten per cent of a data science problem,…

Working data scientist here. As many have said, this is, effectively a Kaggle challenge. I mean honestly at this point, I don't care, at all, how well someone can predict…

Any assessment that directly provides data sets - even with "gotcha"s like missing values - is testing, based on the conventional wisdom, at most 20% of a real-world data science…

No one does good science in 60 minutes.

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…

Here are my high level thoughts after a quick look at the question and some clarification in thread below. - a single question is difficult to evaluate. "Answering a business…

I think some candidates would be open to performing a half-day exercise. But the best candidates wouldn't, which is what drives the anti-selection I mentioned in my previous…

I think at best this is fizzbuzz for DS, which is not inherently wrong. It's nice to know a software developer can write a loop and a data scientist can use a JN, so for weeding…

That's useful information, thanks. I'll add some thoughts on the rubric. [edit]. Initial thoughts: - "data wrangling" scoring difficult given this task - more weight to…

True. But as long as all candidates have the same time limit / same expectation of work depth, and the test providers have a reasonable expectation of how much can be…

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…

I have a number of concerns about the efficacy of this, but they are made more difficult to rank by not understanding how you are planning to evaluate and use the results. Can…

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…

Ok, although I would be wary of using a numerical comparison for anything except catching obvious errors. I should have asked this before, but "data science" is a pretty broad…

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…

I am in the camp to think that this notebook judges data scientists in a way that soon will be obsolete. If I'm given this clean dataset with all of the features properly set in…
