Intel Corporation Product Development Engineer interview questions

I had a Screening call with a manager followed by in person interview with two hiring managers , questions were coding/electronic circuits related , and lasted about an hour , it was an in depth interview but I found it an enjoyable challenge

I got an email from the hiring manager saying they needed to talk more and ask me questions, we set-up a date and time, the interview duration was 30 mins, so I thought it would be an introductury interview. it wasn't, it was a full interview that the hiring manager and another senior engineer attended. we all introduced ourselves and what we do, and then the technical questions began but there was barely any time left. so the interview was concluded,
