PPT round, where I have to pick a complex problem that i have solved in my career. There were various criteria that I have to add in the PPT such as: The problem statement (for example: “Scale our platform to send 10 million emails in 1 hour”)•Why was it hard to solve? What was challenging about it?•Analysis –how was the problem analysed and broken down to arrive at the solution? •Solution –what did the solution look like?•Implementation and Release –how did you test and ensured that the solution worked? •Impact –How did the solution fare once users started using it?•Time and resources that were required to execute the project
