Your question is Work Across Sales and Coding. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
They asked about discovery calls - you had to do a sales presentation. In another meeting you had to write some short code based on the Stripe APIs.
Explain how you would prepare for and execute both practical exercises. Address how you would uncover customer needs, present a relevant Stripe solution, and clarify requirements before writing code against Stripe APIs.
