starting to believe something is wrong with me

i keep getting rejected even though i have faang and startup experience (senior) and im starting to think there is something bad or wrong about me. maybe its my attitude, personality, hard skills, soft skills, maybe theyre somehow able to see how defeated i am after all these rejections and that rubs off on how im coming across even tho i feel im doing a good job of hiding it. maybe its my references. maybe i have a glaring skill flaw

i dont know anymore, im just feeling defeated.
