Hello,

I have a phone screening round of 60 mins. It will consist of Coding (basic DS & Algo without any libraries in Python), Data Manipulation (SQL/Python), and Stats/ML. Any help is much appreciated on the difficulty level and types of problems for the coding (DS & Algo) I should be expecting. Also any suggestions regarding how to prepare and materials?
Thanks so much!

    - Complexity Analysis (Big-O)

    For the stat:
    • Hypothesis Testing
    • Supervised Learning (Classification, Regression)
    - Model assumptions
    - Evaluation metrics for model fit - Interpretation of model output - Bias-variance trade-off
    - Regularization
    • Unsupervised Learning

    For data manipulation:
    • Group-by aggregation
    • Join (inner, left, right)
    • Subqueries
