> unnatural conditions including (1) time limits, (2) forbidding research on Wikipedia or StackOverflow, (3) forbidding collaboration, and (4) forbidding the use of libraries

The above indeed does not make sense, unless you're hiring a solve-puzzles-as-sports person.

I don't think it's enforced by HackerRank, though. It must be the employer's requirement. If so, their hiring process does have problems.

I think this is enforced by HackerRank, colleague recently griped that they couldn't set the time limit higher or get rid of the messages forbidding x,y,z.
