Was given a choice to complete 1 of 3 tasks, on my own time. The one i picked used a publicly available API to get a list of businesses , of certain types, given a location (such as city or zip code etc) ad provide an appropriate UI. We’re interested in your skills at using APIs, data sets, and services to build useful and functional user experiences. For these puzzles, you could do most of the code server-side (for example, a Java, Node.js, or Python back-end generating HTML), or client-side (all browser, or even Mobile iOS or Android). Puzzle #1: Restaurant Search Create a web interface that helps you find a local restaurant based on cuisine type and location using either the Yelp API or Yahoo’s YQL API for local search. You can add any specific features you think are useful, but it should Allow searching by location Allow selection type of food (e.g. Pizza, Italian, Tapas, etc.) Allow sorting by rating or distance Format the results as a list however you prefer. We are more interested in the content and usability of the interface than in polished visuals. For example, what are good ways to enter the location? What cuisine types should be used? Can users modify their sort criteria.
