- a coding test in a short time frame (30-90 minutes)
- implementing some singular function that expects a singular answer
- expecting time/space complexity optimizations, often those not naively thought about in said short time frame
- in synthesized test environments (as opposed to something representing a real world environment)
to fall under "leetcode like interviews". Log parsing can fall into either camp depending on the prompt. Once it's asking you something esoteric like to locate a timestamp in Log(N) time it starts to fall into Leetcode territory.
