Every business collects data, and it's the job of the data analyst to analyze, interpret, and communicate that information in a way that will help drive company decisions. Employers will be looking for candidates with strong technical skills as well as a knack for conveying data in an easy to understand way. Expect a fair number of technical questions, which may include an analytical case study and a math brainteaser.
If you have 10 bags of marbles with 10 marbles each and one bag has marbles that weigh differently than the others, how would you figure it out from one weighing
hmm, drop all the bags a the same height spread out and see which bag make the biggest mark on the ground.
Add bags one at a time to scale. Should be the same increment of weight added until you add the bag that adds a weight value different from all the others.
hint: use the number of stones to code for each bag.
