my friend just finished his interview at OpenAI today

my friend just finished his interview at OpenAI today and I asked him how did it compare to the questions that you prepared for. He said, I feel so bad for product managers because your interviews are way harder than our software engineering interviews. And I'm like, what? You just finished one of the hardest interviews, I'm assuming, and he mentioned there were two differences. And so I want to get y'all's take on it. First is that software engineering interviews are mostly leetcode, which are case questions. And it's a double edged sword because they're pretty different from what you do in your day-to-day job as a software engineer. But what's nice is that leetcode questions are pretty well documented. And no matter what your background is, you can study for these and get better at them. Versus product manager interviews, the fewer case questions you get, the more senior you go, which is actually a bad thing. It's much more actual domain expertise. So if you haven't worked in a specific domain before, there's no amount of studying that you can really do to make up for it. For example, if I'm applying for research product manager roles, which means I work with research scientists to develop AI models, this isn't something you can just casually pivot into if I've never done this before. There's just no amount of studying that I can do even prepare for these roles. Another difference is that PM interviews, there's a lot more company specific prep that you have to do. If you get rejected and start interviewing for other companies, it really feels like
