Generally speaking, it's a good practice for interviewers to turn whatever problem they are working on into a simplified interview question and give it to the interviewee. This way they'll know if the candidate can solve problems that they'll actually face if they get the job. Interview questions related to finding shortest path, min/mix of whatever, finding x numbers that sum to y etc.. will only tell the interviewer if the candidate has prepared academically for the interview. In the end, the interviewer will probably end up hiring the wrong person. A person who has done his/her homework but cannot solve the simplest scalability problem.
