That is a difference people make in their mind. I don't see a difference. The criticism is the critism. If you receive enough negative feedback on PRs after being hired, you will be fired for not be good enough.

The only way to take away the stress of an interview is to not care about the outcome. I don't and interviews are stressful for me. I present myself as I am and if they don't like it oh well, but that is a confidence I think most people don't have. I have been like this since I was junior so it's not the arrogance of experience. It's not even the confidence of easily being able to get jobs because in my early career it would sometimes take months to get a new job. I'd ask for feedback if I could get it and accept or disregard it. Some feedback amounted to, "this wasn't the job for you" and that's okay.

I just don't think it's worth worrying about any particular job when hiring is like dating. You can be perfect for one job and an obvious no for another, so it's not worth worrying about the outcome. They like you or they don't.
