Engineer Interview Questions

Engineers are responsible for designing and building products. In an interview context, expect to be quizzed on your technical skills, and also evaluated for your ability to work as a part of a team to get things built. The specific questions you are asked will depend on what type of engineering position you are looking for such as a specific engineering discipline like software engineer, electrical engineer, or mechanical engineer.

Design an alert system. You have 500,000 hotels you represent, and about 250,000 are visited each day. You want to track hotel page visits such that, if more than 10 visitors per a) 5 minutes, b) 1 hour, and c) 24 hours occur, then a (different for each time period) "alert" appears when someone visits one of those "hot" hotel pages. Don't worry about the UI part, just design the underlying alert system. Then optimize your solution for space.
