The entire process took about a month. The first-round interview was a phone call with a recruiter. The phone call was very direct and involved questions about skills (e.g. previous work with data, software, knowledge about the company) and only lasted about 10 minutes. The second round was a case study that involved preparing a client PowerPoint presentation on risk for patent litigation for microchip company. You are given an Excel spreadsheet with figures and errors and a partially filled PowerPoint presentation.
