A friend is doing masters in management of information systems. What are the resources for preparing for data analyst / business analyst for a college grad ? Is there a website similar to Leetcode for these roles ?
Focus on SQL. It will also help if he has experience in R/Python. Doing some MOOCs from Coursera and Udacity for data analytics will help as well
For a fresh college grad I would say focus on SQL and basic stats..they would not expect a lot in terms of experience but a good attitude and presentation would be the key
