Rejection is just a part of life.. I was really scared of rejection till one day I just gave in and told myself that, I'll never get anywhere playing the safe hand.

My advice is go on interviews you don't even care about in hopes to get rejected. Some places might tell you to leave like half way through an interview which is awkward, but most will shoot you an email or you just never hear from them.

Once you get a few rejections under your belt, you learn its not a big deal. I've know some incredibly smart people get rejected. Most times you get rejected because its not a culture fit so its for the better.
