This is my own experience: if the recruiters don't call me back, that means I fail.

No - it just means the decision has been made, and you won't be hired.

Which is different from "you failed". It could just as easily be their failure to evaluate you properly.

I came here to say this. You didn't fail. Its just not a good fit. maybe they are incompetent, and saving you heartache in the long run. Maybe they weren't able to extract your relevant experience. maybe you didn't share effectively. Just keep moving and good luck!
