That’s weird. Any senior developer worth their salt surely should know that LLMs produce a lot of weird nonsense with one-shot prompts, so they need to talk design first, then code the implementation.
This said, IMHO one-shot is worth a try because it’s typically cheap nowadays - but if it’s not good (or, for interview reasons, unavailable) any developer should have the skills to break the problem down and iterate on it, especially if all learning/memory-refreshing resources are so available. That’s the skill that every engineer should have.
I guess I must take my words back - if that’s how nowadays “seniors” are then I don’t know what’s going on. My only guess is that you must’ve met a bunch of scammers/pretenders who don’t know anything but trying to pass for a developer.
