From an applicant perspective
From an applicant perspective, Codility is poorly designed. I have no doubt, from a recruiter perspective, it gives confidence. But it hides the randomness of the results. 1. It is not possible to test all the cases. They are hidden. Performance is evaluated only after you submitted the task. 2. The number of tasks is not indicated. You cannot manage your time properly as an applicant 3. You cannot come back to a previous task. Meaning, any spare cannot be used for a task you would like to improve Either you get a perfect score, or your score is immediately low, as you get no chance to correct the code.
