Overview
Monthly workshops designed to help you understand the various types of data science roles and technical interview processes. Meets online on the first Wednesday of each month at 12pm ET.
Workshops are paired with weekly study groups and technical interview resources and practice problems to help you progress.
We strongly recommend giving yourself at least 3 months to prepare for technical interviews.

Program Content
Note: Program Videos below are from the Spring 2023 cohort. They will be replaced with the Fall 2023 cohort after each event passes.
We have a large collection of Technical Interview Prep materials and resources available through the "Program Content" button below, including:
- Overview of what a technical interview is
- Subject matter resources (e.g., machine learning practice problems, SQL tutorials)
- Interview format resources (e.g., preparing for white boarding vs. case studies vs. take home data challenges)
- FAQ (e.g., how long does it take to prepare for a technical interview)

Technical Interviews - Part 2
White Boarding & Paired Coding
In this video, Lindsay Warrenburg discusses the Paired Coding and White Boarding types of technical interviews and then provides participants with some sample problems to work on in groups. Space for Technical Interview Prep group work has been provided in our digital campus: https://www.erdosinstitute.org/campus
Project/Homework Instructions
For those who want to have practice interviews, you have the option of signing up to meet with small groups. If you sign up, I (Lindsay) will add you to a private Slack channel where we can communicate about these problems. I will also add you to our private GitHub repo, which will only be visible to those who are actively preparing for interviews.
There are 9 sets of practice interview questions. Here is the way that will work:
- Every week, you will have an assigned study area (example: statistics, product/business knowledge). During the first part of the week, you will be expected to read the corresponding chapter of "Ace the Data Science Interview" and the relevant sections in our Technical Interview Resources page.
- At the end of the week, you will meet with your practice group on Zoom (schedule your sessions here). During this session, you will go to our GitHub page and open that week's problem set. Each group member will take turns answering the questions as if they were in an interivew. This will test not only your knoweldge of the topic, but how well you perform under pressure, simulating the interview experience.
