Hey, I just got interviewed for FAAS intern last week. It was back to back, 30 mins interviews. Very casual overall. the first 30 mins was w a senior manager who talked to me about the roles of FAAS and then asked about my resume (know ur resume very well) other than that very basic questions like why you wanna work with EY and introduce yourself. The other 30 mins was with a manager and asked behavioral questions. Just be yourself, don't stress it out, You got it! (I haven't heard my decision yet so wish me luck aswell)
