I'm from the GTM side, and I can offer my two cents relevant to that.
• Early in my career, most of the sales interviews I've been through/the interviews I observe now for entry level SDRs have at least one email writing assignment. I think that goes straight out of the window. If you know how to ask the right questions to AI, it can draft a beautiful email. This is imperative considering email assignments for interviews are done on a hypothetical situation, and not a real person, eliminating the argument of "Hey, but AI can't personalise!".
• Deep-diving/research assignments on a company, understanding it to bare-bones becomes easier with GPT. A simple search command of 'Explain me everything about Springworks' helps me understand essentials, ranging from year of inception, to products and services, to USP, and what not. Such assignments would be useful, but might not accurately gauge the skill you're trying to evaluate here (researching).
