CodeSignal. 4 questions in 70 minutes. I feel the time aspect of it is the hardest part. 4 questions in 70 minutes is hard considering each problem statement is a long essay. I shouldn't have to read War and Peace for every question.
The test seems like a pure iq/speed test. If you did great on your SATs you will do well here. Very little to do with actual software engineering. It is a very frustrating experience and I feel like the companies using it are sending it out in mass to candidates making it a waste of my time. In the future I will just politely decline CodeSignal as it just feels hopeless.

Question 1
NDA pointless to disclose anyway since it is a long essay you are better off reading War and Peace.
4 rounds of interview including coding , design , case study, behavioral after clearing the code signal assesment. Coding was medium hard of 2 questions each. case study and system design was difficult.
This took a bit longer than expected, stretching over several weeks. The technical rounds were intense, featuring an LRU cache implementation and a problem on detecting duplicate transactions within a 60-second window. I was nervous at first, but it clicked for me when I realized I had practiced a similar approach on PracHub just days before. Unfortunately, I didn’t receive an offer in the end, but the experience was a solid learning opportunity. The behavioral questions felt straightforward, so I wish I had made a stronger impression in the technical segments.
