Yeah, it could be slightly gut wrenching the first times. My focus when I started out in software development was to pass the interviews.
Today it has shifted to also finding out do I want to work here?
For me the best interviews are more like good discussions and if a company treats it more like a pass or fail exam rather than a discussion I see that as a warning sign that this is how they will see your work as well. A continuous individual pass or fail exam rather than work together to build the best possible product.
And yeah, don't be discouraged about failing an interview, everyone who's ever done anything interesting has too. (Probably)
