1: Phone Interview with basic background questions followed by 5 basic arithmetic questions to solve. The answers need to be right, else you don't proceed ahead.
Some of the Topics: weighted averages, break-even quantities/prices, simple interest, profit calculation. (I found most of the sums asked already here)
2. Hackerank Challenge - R, Python, Java, JavaScript
3. Data Challenge - Given the dataset you need to perform analysis and give recommendations (Difficult)
4. On site Interview : If you get one, your recruiter would provide you on how to prepare and topics needed in detail
a. Case Interview - 2
b. Data Challenge presentation
c. Behavioral Interview
For me Case Interview Topics I already found them here, though I have summarized them and here they are here, I bet you practice all of this, you get the job
