I think that tasks should be changed every 1 year for example.
ReplyDeletePeople who solve tasks, exchange information with colleagues, publish the content and solutions of tasks on forums, etc.. Systematic knowledge about the tasks becomes publicly available.
We are not removing any tasks from the pool, because this can be really painful for recruiters in the middle of the process. We mark tasks as "wel-known" once we see that its screening ability diminished. We keep adding new tasks (average one task per week). Interestingly, some tasks do not deteriorate even after long time on-line. We track occurrences of solutions to Codility tasks online and it shows that most of solutions on-line are wrong. This is beneficial--cheaters trying to copy solutions are likely to copy the wrong ones.
DeleteWhat You think ?
ReplyDeleteDefinitely you are right. But changing questions should depend also from the usage of each question. Some are more popular than other.
