Interestingly, I have never really used algo questions in my hiring. I also have never worked in companies where any fundamental innovation in computer science takes place but rather we need strong application developers who understand particular business domains and can make the end use cases work for business clients. I have used coding assignments with junior hires where comparing several candidates based on school work is sometimes challenging.
