I applied online. The process took 2 days. I interviewed at SumAll.org (New York, NY) in Apr 2014
Interview
I was first asked about my resume. I was then asked why I wanted to work for them. The main part of the interview consisted of three challenges, which I was given a couple days to complete. They were typical data science tasks. One tested knowledge of data bases. One tested knowledge of API's. One tested basic machine learning via a text classification challenge.
Interview questions [1]
Question 1
Was I concerned with sparsity of my solution when utilizing an SVM? Why or why not?
