Hello blind community,

I have an upcoming virtual onsite(4 video interviews) with Walmart. The interviews are divided in 4 sections - AL-DS/ML-Statistics/CV/ML Design. All rounds will be conducted on Hackerrank. Can anyone guide me on what is the best way to prepare for each round? Has anyone gone through this round recently? Any tips will be genuinely appreciated. Thanks. #walmart #datascience #interview #onsite #machinelearning #dataanalytics #data #datascience

    I have interviewed not as data scientist, but as data analyst at Walmart. And i had 2 rounds of interviews with data scientists, mostly going really technical. I was given business user cases and was asked how i would solve it, then going details about the model i would build. E.g. I said i would build a linear regression model and was asked what is a linear regression model, what do the independent variable coefficients correspond to? How does the optimization of coefficients mean? What is the equation of a linear regression model. What are the assumptions you would make and what data checks you would do? So they go really in detail of the solution you build. Hope this helps!

    Few of my friends have interviewed and I have been told
    1. The recruiters are of no help
    2. Every team is designing their on interview processes - one my friend was given a data Modelling challenge to complete in 1.5 hours during on-site and was told as feedback that he didn’t have to model and rather do data analysis.
    I would recommend finding out interview structure for the team you are interviewing with.
