They filter out positives, though according to hiring managers, that's the point. I had a frustrating experience with a hackerrank recently. My code was passing all of the public test cases, but failing one of the hidden test cases, and there was no way (that I could find) to debug it. Incredibly frustrating. Even if you're a long time senior developer who can code, don't be fooled into thinking you can pass one without practicing on the particular platform.
