How to not get discouraged while searching for a job?

The market has not been forgiving, especially when it comes to interviews. I am not sure if anyone else has noticed, but companies seem to expect flawless interviews and coding rounds. I have faced a few rejections over the past couple of months, and it is getting harder to trust my skills and not feel like I will be rejected in the next interview too.

How do you change your mindset to get through a time like this?
