These days a lot of folks are curious about interview/ hiring process of top technology companies like Google, Facebook and Amazon etc. Sometimes understanding the hiring process in advance helps a lot but there are couple of very simple fundamentals that all aspirants should understand: (A) Getting selected in an interview shows that you are capable of passing but at the same time it doesn't determine and show you your self worth. (B) For every skill there are really very few folks who are at the top, rest everyone else has someone for other who is more capable than them. This is a fact that the interviewing companies are also aware of and they know what to expect from most of the candidates. So all you need to do is believe in yourself and don't ever think that you are inferior to someone because negative thinking will lead to self destruction.
