If you like reading someone with voice, Matt Levine with Bloomberg is pretty entertaining, even when he is banging on about securities fraud or SPACs. This is a funny recent piece about weird interview practices at PIMCO (a bond investment firm which apparently would yell at people in interviews*). The below reminds me of grad school a bit:
But “mock client presentations”? When I was in a client-facing financial-services job I don’t think I ever did a mock client presentation, and in hindsight I hate myself for that. Of course I should have been doing mock client presentations to prepare for real client presentations! Of course those mock client presentations should have been so ludicrously rigorous that they left me in tears! Then you go to the real client presentation and you handle all of their questions with ease, because you were so over-prepared for the terrifying mock presentation, and also you are warm and charming and personable and excited to be there because it’s so much nicer to be with clients than with your colleagues. “I really felt a connection with them,” you say after the client meeting; “they didn’t make me cry once.”
I think this is actually a pretty decent way to prepare for interviews, i.e. go in front of a trusted group of friends two weeks before an interview presentation, and have them chew on you lovingly for two or three hours. Then you have a drink, take their advice and adapt your presentation, and do it again before your interview until you're smooth.
Clearly in the finance sector, folks like to yell and curse and be mean; I don't think that's necessary. It's no fun to subject yourself to rigorous questioning, but it's good practice to have friends who can be critical of your presentation and give you good feedback. No tears needed, but definitely checking one's ego at the door is good.
