I've been on the mailing list since the initial beta a few months ago, and found the questions to be very helpful with my data science interview at Facebook!
I've been enjoying the mix of questions coming out Data Interview Qs. The balance between stats, data manipulation, classic programming questions, and SQL came in handy during my Amazon interview.
Data Interview Qs helped me land a quantitative analyst role at Google. The ROI here is great and would recommend for anyone seeking a role in the data science space.
