Started the process with an application/resume submission, followed by a Virtual Job Tryout. After that, I was given a CodeSignal task where I had to answer 13 questions within 2 hours, based on a large spreadsheet with numerous data tables. I was invited to a Power Day after completing the CodeSignal assessment. Power Day consists of three 1-hour-long interviews; two of them are business case interviews and one is a product interview. Business case interviews involve a hypothetical business in a particular scenario, where the main elements of the interview are creating a framework to increase profitability, calculating important metrics based on provided numerical data, and suggesting recommendations based on your quantitative analysis. The product interview requires you to have thorough knowledge of a digital app or social media platform, where you will describe its business model (what drives costs & revenues) and make suggestions for the company to increase profitability. C1 is the only employer I know of that does not have a behavioral interview component for its internship program (which is why I really liked the hiring process). It's all about your capabilities.

It was around 10 questions of data analysis and graphs and calculating percentages. Just know how to calculate these and understand what the data they give you is talking about. Overall, a pretty typical interview for business analyst role.
