Micron Technology Process Equipment Engineer interview questions

First round with managers were good and fun. Second round senior manager interviewer was rude. He demanded me to show my results and pin-pointed the B- that I got throughout my 4 years academic. He told me he couldn't understand Malay Language because he is Singaporean (Bs, cuz Malay Language is SG national language). Interview is an exchange, not worth my time working with people like this.
