When people don't get an offer after a technical interview, it's typically about technical skills. Even if they think they did well because they verified their answers online. Often, although their answers were eventually correct, it took them too long to get there which the interviewer perceived as weak problem solving skills.

Does CtCI publish those times for its problems? How would I know I'm too slow to solve a kind of problem before interviewing?

No, I don't publish times. The times are misleading. Interviewers often give hints, which can dramatically change the amount of time. And there can be random factors that change the amount of time.

triplebyte mentions taking a particular problem from CtCI and solving it within 30min on a whiteboard (pen/paper, plaintext editor).
