Yeah that's not. Notice how the one below it is also a joke, the "banana stand" one. The others read as legitimate.
I’d be surprised if the PornHub one is legitimate.
I've applied to OpenAI four times in the last two years, and in my experience if you're rejected, they simply don't respond at all. I haven't gotten any rejection emails, but I seriously doubt they've been been considering my resume for eighteen months.
