What topics are covered?

Data science, machine learning, and analytics interviews are extremely complex. Luckily, we have you covered.

  • Python Scripting

    Test basic skills within coding in Python such as text parsing, reading files for writing scripts, or building features out of datasets in Pandas.
  • SQL and Analysis

    Tests data analytics, ability to pull your own data for building models, and different interpretation of datasets and metrics.
  • Product Intuition

    Understanding how to solve problems before pulling data and how to showcase analytical knowledge to empower business decisions.
  • Algorithms

    These questions test how to write complex implementations of data structures and algorithms for machine learning and engineering focused roles.
  • Modeling

    A focus on testing the interpretation and validation of model building, model case studies, and showcasing an understanding of tradeoffs between technical and business decisions.
  • Probability

    Based on understanding the principles behind many algorithms and models.
  • Statistics & AB Testing

    Needed to understand the basics of statistics, experiment design, and how to effectively measure and implement AB tests.
  • Machine Learning & System Design

    Understanding of how to build, deploy, and test machine learning models in production as well as how to architecting database design for scale.

Get Expert Feedback

Take the uncertainty out of interviewing. Sign up for our Mastery Package to get access to a 1x1 coaching session with a data science professional. 

  • Practice with a Professional

    No one is naturally good at interviewing. Data science interviews today are not only non standardized, but also graded on a combination of technical, business, and communication skills that is tough to replicate without consistent practice and feedback.

  • Expert Knowledge

    A professional data science coach can help you point out gaps in your knowledge before facing the real interview. Interview Query coaches are matched based on specialization (machine learning, analytics, product, etc..), timezone, and availability.

  • Customized to you

    Each data science coaching session is customized to any area you need improvement. Some examples of a 1x1 session would be breaking down an interview step by step, conducting a mock interview with in-depth feedback, or going through strategies to tackle different problem types.
