Insights on Walmart Labs MLE interview process?

1. Will I be tested on SQL? What will be the structure of the rounds - coding vs ML vs design?

2. Are questions based on data structures (LC style) or data manipulation based (numpy pandas etc)?

3. I am comfortable with basics of ML - regression, clustering, regularization, overfitting, bias variance trade-off. What else do I need to study?

4. How important is system design? I am not a new grad.

    Lol, use it for practice and prepare for ML engineering role at FAANG. Avoid that place, as far as I know, most good folks have left or are on their way out given its internal struggle with employee logistics and culture.

    Interview rounds depends on team. Typically, LC medium coding, ML and stats basics and ML system design. Haven’t heard any teams ask SQL or numpy, pandas style q.
    Best to ask recruiter/ hiring manager.

      Is it important to memorize the cost functions and their vectorized forms?

      Should we know how to derive neural network forward and backprop?

      New grad level. Wondering if we should be well prepared to derive them on the whiteboard

      If some one expects you to memorize loss functions please dm me :). I would personally focus on why than what? What can be googled , why need to be understood ...

      It’s good to know what loss functions are used and how. But I doubt that you will asked to derive them
