Just a learning from experience,for these kind of tasks, better prepare a project architecture beforehand and just add missing pieces on interview time. Never rely on internet they may provide.Take a wifi dongle! Also it's better to go by brute Force approach if there's no clarity provided by interviewers on end time.
