Medtronic Software Engineer I interview questions

First round of telephonic discussion on c/c++. Then F2F interview in 2nd round followed by discussion with Manager and Director on same day. Then HR interview on another day to discuss salary. The HR said I should expecting offer letter by end of week and was also asked to login to their portal. Then no response from the HR team for 8 weeks. And then I receive an email saying the position is offered to other candidate.
