For infra/systems/devops engineers, Avoid - they screen you via a Codility test and they expect you to have a 100% score for it, with a 60min time limit for two lengthy problems. Anything below 100% is not enough.

Testing infra engineers for algorithms is plain stupid, completely irrelevant and a total waste of time as it does not translate as a test for any other infra specific skill one might have (problem solving / analysis / troubleshooting / systems design / et cetera).
