Job interviews are hell, especially for people starting out. They are easy if you feel like you have choices and don't need to be perfect... But recent grads have a "this is your future" thing piled on them.
Honestly I'm not surprised, I've done a couple interviews for Japanese companies and they were almost all terrible. Like they think you should be eternally grateful if they offer you a two bit job for the same pay as McDonald's. And you better dress better than your interviewer!
I guess this is why, despite a humanities degree, I ended up getting a 2 year tech degree and working as a factory mechanic? This is a great reminder of why I hate white collar work.
