I can't speak to how they are now now, as this was about ten years ago, and I don't want to be too specific as they are extremely litigious lol, but...
I applied for a jr position, something I was not overly qualified for but could have easily done at the time with some training. I am now a Sr in that position, so the capacity was there. Anyway, round one interviews are fine, nothing stands out there, but like I said it was ten years ago, at least. Then for the next interview I had a call with the director of the department I was applying for. He was short with me from the start, and I remember being incredibly taken back by his attitude before we'd even gotten into the interview. I have extreme social anxiety and am admittedly terrible in job interviews, so being thrown off right at the beginning of the call didn't help things. Then there seemed to be a misunderstanding on his part about which level of job I was applying for. He clearly thought I was underqualified either way. He asked me what I now can confirm were insanely technical and architecturally specific questions and then when he'd finally managed to trip me up on an answer he completely unloaded on me. For several minutes he berated me for wasting his and Nintendo's time and then told me I was being blacklisted and to never apply for a position anywhere at Nintendo ever again. Which, no problem. Even though I understand he was just a jackass, I'm still recovering from it to be honest. But extrapolating how he must run his department and what that must mean for the culture over there, I have not been surprised by the downfall of Nintendo in the least. Shit is as shit does, my friend.

i think it’s a combination of two things:

1. these people had an emotional attachment to nintendo and it’s games growing up, or knew someone who did, so thought very highly of it. when faced with the reality that nintendo is just like any other corporation, aka they only care about their profits and nothing else and will act accordingly, the fall from heaven was brutal.
2. the main targets of nintendo’s shittiness are its own customers and fans. microsoft may be helping mass murder of people in Palestine, ubisoft may have protected the sexual abuse of their employees by management, rockstar may do union busting… but gamers are none of these people. gamers are "consumers", and highly lacking in empathy. so, in their eyes, nothing is worse than being "anti-consumer". like, ask any gamer if they like ubisoft and, if not, why. they won’t talk about the sexual abuse, or crunch… they’ll talk about bad overpriced games and microtransactions.
