One starring every company that uses HackerRank to send take home tests to candidates. Some of the many problems when forced to use a browser IDE * No debugging. You cannot step through any code to troubleshoot issues * Dysfunctional IDE. All kinds of bugs (as you would expect in a browser IDE), auto complete removes the code instead of completing. * Hidden test cases. How are you expected to fix the test cases when you cannot see what is failing * Buggy boilerplate. The code they have to use the class was functioning in a way that output an additional empty line at the end of all output, which would fail the tests even if the class was functional Half of my time was spent fighting with HackerRank and I would never recommend taking this assessment.
