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.
Interviewed for an engineer position, the interview was a joke. Asked basic OOP question with a few follow ups - no system design portion. Interviewer was very laid back and chill, didn't take it to seriously.
Was not too difficult. three total interviews all on the same day back to back. technical one, behavioral one and a case which was more of just a debugging question
Expecting a challenging experience, I found the interview at Capital One to be intense, particularly during the system design section. The question on designing a rate limiter with a token bucket algorithm took me by surprise; mid-way through the problem, I realized it was very similar to a drill I’d practiced on prachub.com just days earlier. The technical rounds included several DSA questions, and the interviewers were thorough but supportive. Ultimately, I received an offer and happily accepted, feeling well-prepared despite the pressure.
