Micron Technology Engineer interview questions

Long Multi-Stage Process that took quite long but was handled well with multiple staff members assisting along with F&B being prepared for us. The interview was standard with the department manager.

Was called for a different role from the one i was applying, went onsite for the interview. The interview process itself was easy, just general behavioral question, experience, and situational based. The planning for the interview is a mess. Even though I applied for a different role, they did not give me a proper job description even when i specifically requested for it. My interview also got delayed for an hour. After the interview, I was told to wait there and I waited for almost 2 hours, but no one informed me (and also the other people there who were waiting) off anything, then they just suddenly said they ran out of time and told us to go home
