The DS challenges were perfect to prepare and helped me get a DS job at Pinterest!Dorna Bandari
As part of the 1:1 coaching I offer on the main site, I would ask candidates to send me the questions they were asked in the on-site/phone interviews and I collected them on a private twitter account.
From that collection of questions (and this can also be verified by checking on Glassdoor), it is obvious that data science interview questions are often about:
Such as the famous Facebook question: "Should I add a love button?"
"I am launching this new feature, which metric should I use to see if the feature is successful?"
"How do I improve engagement on FB?" or "How do I improve host response rate at Airbnb?"
"FB wants to test a new algorithm to recommend friends. How can I design a test to see if the new algo is successful? Why can't I just randomly split users in test (new algo) and control (old algo) and compare their behavior?"
DS candidates are often really surprised by these kinds of questions and don’t know how to answer them. To my knowledge, there is currently no resource that explains how to answer these questions and many people asked me if I could create one.
You will not be charged when you pre-order. You will be charged when you receive the book, i.e. on Nov, 7.
The book will never be sold independently for just 59$, except for during this pre-sale. That is, it will be only sold as part of a several hundred dollar package including other stuff. So, if you are only interested in this book, this is your only chance
There will be 40 questions and answers in the ebook.
The questions will be taken from this private twitter account, focusing on the product questions. If you want to see the current list of questions, just send a follower request, and I will add you.
Some other question examples are: “Give an example of a case in which you run an A/B test. Test wins with significant p-value, but you still choose to not make the change.” or “How would you use data to evaluate if it makes sense to implement two-step authentication when users log in?”.
If you are interested in a specific question that you don’t see there, just tweet your question @DS_JobInterview (or a private message) and I will add it to the list of question candidates.
If you want to influence the final choice of questions, just favorite or retweet a given question. I will definitely pick the questions with the highest number of favorites/retweets.
This book is for you if:
