Yup. More mental "shortcuts" that seek magic "signals" to avoid both evidence and pragmatic interviewing effort testing both business problem-solving critical thinking and cultural fit. There are no shortcuts. Furthermore, "competitive" programming has little to do with the real world, and it's more about showing off and ego inflation.
Reading between the lines: Problems that are typical of software engineering interviews and in competitive programming are poor evaluation of one's capabilities as a professional software engineer.
