Intel Corporation Process Technology Development Engineer interview questions

referred by a former labmate. it takes a whole day, quite exhausting. the hardest interview for me is the one before my presentation... after that, they basically ask questions based on my PhD work, which is not difficult to answer. Overall, a great experience since Intel is a very generous company. The only bad thing is they did not extend an offer to me though and it is their rule not to provide any critics to candidates.
