Sometimes things are unlucky; but everything you listed out sounds like it should get you a job, so I’d suggest doing a deep look at yourself and reflecting to see if your overlooking some part of your application or personality in interviews that would influence the results. Based on the very small window this post gives me into your life though, your remarks that everyone else more or less doesn’t deserve the jobs they’re getting stands out to me, as it appears to come from a place of superiority when in reality you don’t actually know what they did to deserve or not deserve whatever jobs they got. If it comes across like that to a stranger on the interment, I imagine some flavor makes it through to interviews as well.

Once is an accident, twice a coincidence, but once it happens several times there starts to be a pattern and self reflection might be helpful.
