McKinsey QuantHub Assessment (Data Science Analyst Role)

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!

Hello!

Unfortunately no, although I have looked for examples in several occasions and haven´t found them. It´s still really niche :(

Good luck!

Cheers,

Clara

No worries! I completely understand. I actually ended up taking the assessment and passed! For future awareness / for anyone who was wondering, here’s my personal recommendation:

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

For storytelling you should read Barbara's Minto book which is Mckinsey's bible on communication: The Pyramid Principle

Based on what you described in your comment this is exactly what they are looking for.
