I applied through an employee referral. I interviewed at Rio Tinto (Perth, Western Australia) in Oct 2020
Interview
Stage 1: Initial interview with 2 managers.
This is a standard fit interview, asking questions like why I wanted to work with Rio Tinto, CV review.
Stage 2: Inbox Case Study
You get 3 hours to review an investment opportunity. The whole process is a quick intro, followed by solo work for 3 hours, ending with a review with some senior analysts.
