We've added Python/Pandas support!
Why Python?
In the last few years, companies such as LinkedIn, Apple, Spotify, and Google started to mix the data processing and data engineering interviews by asking skills beyond SQL.
A candidate is expected to solve the same data manipulation and transformation problems using Python.
For example, a candidate is asked to first find the top 3 products from the past sales table using SQL and then answer the same question with Pandas.
Why Pandas?
Pandas is simply the most popular data analysis library in Python that every data scientist candidate is expected to know.
How to practice your questions in Python/Pandas?
To practice 200+ coding questions, simply switch the default engine to pandas.
Since pandas support is new, we are limiting this feature to our paid customers for now.
If you want to practice those coding questions using pandas, please upgrade to our premium plan.
