Dear HackerRank, please stop existing 🙏
Till date, I've never been able to pass atleast one of their test cases, despite the solution provided satisfies all the test cases including the expected ones.
Just because of this, I've lost many opportunities at good companies.
Is there anyone who has successfully passed all test cases in a HackerRank OA interview round ?

Bro.. seriously.. I think you should get familiarise yourself with hackerrank. I have given several test on that platform and passed all the test cases. It's cool platform with auto complete and user friendly.

I know. I have completed many challenges on HackerRank. I know the platform very well. Heck, I use it more than leetcode. I'm even familiar with the new AI integration and everything.
It's just that test cases only fail when giving an OA interview round. On other times, no issues.

Hackerearth is way worse

It is oudated. It doesn't even have the latest version pf SQL

Sometimes yes all of them, and sometimes not all of them Reasons might be:
- Tough one (like amazon, recently)
- Don't know why some unit test cases failed...there was a case where changing event from mousedown to click worked in a react test.
- May be some weird test cases or platform glitches... Also OA is just another filter to hire candidates for recruitmers because of lot of applications.
