Hi Everyone,
I am preparing for an online QuantHub assessment for a Data Science Analyst role at McKinsey. The assessment has the following modules: Storytelling with Data, Analyst, and SQL.
Do you all have any tips/advice for preparing? I have completed the practice tests for the following: SQL, Wrangling, Storing, and Exploration. Any additional insight / resources would be extremely helpful.
Thanks!
1. SQL: practice easy / medium questions on Leetcode and Hackerrank
2. Analyst (Data Wrangling, Exploring, Storing): Understand data architecture / warehouse / Snowflake principles (i.e. asynchronous replication, load balancers, etc.). Also, practicing SQL was helpful here (some questions around ‘which one of these queries would lead to an error?’)
3. Data Storytelling: Just understand key principles in data visualization (i.e. know when to use certain graphs, etc.) and interpreting graphs
