The final stage is highly intensive and centers around a practical business case study and a formal presentation. You will be given a prompt and a dataset, and you will have a few days to build a comprehensive presentation.

The timeline above outlines the standard progression from initial contact to the final decision. Candidates should expect the entire process to take approximately three to four weeks, depending on team availability and scheduling. Use this timeline to pace your preparation, ensuring you allocate ample time to build and practice your final presentation deck.
