It was awful. CTO asked me bunch of questions about library management system. How would I implement one. At the end he told me he will mail me coding challenge. Library App Dev Test PART 1 You just got a your first client as a developer. They want you to build a Ruby on Rails app for their small town library system. The core functionality of the system is: - assume there is only library - the library system will have have many users - a user must have an account to take books out at the library, they may sign up using their email and a password - the library system will have many books - assume there are multiple copies of each book - a user can check out many books at once; the book must be returned 1 week after checkout date. - there must be a log of who checked which book out when, and when it was returned; in terms of UI, thing of this as a page where a system user can drill down on a particular copy of a book and see the full history of that book - who took it out when, who returned it, etc. - a user who is not logged in should be able to see the full list of books in the library, but not "check out" any books - only a user who is logged in can borrow a book; next to each title, there should be a button which will say "borrow" - this button is only available if all copies of the book are not currently signed out by other users. - the user needs to see a list of books they currently have signed out, and their due dates; to "return" a book, the user simply clicks a button next to the title of the book which will say "return" - there must be an administrator user who can edit the details of books, add new ones, add new copies of a book, etc. - the details page for each book should show the status of each copy of a particular title, including who currently has it signed out, if applicable - every day at midnight, users with overdue books must be emailed - the list of potential books is attached as a CSV file, which you will need to load in Deploy this app on Heroku; send me a link to the app, as well as a link to the source on git. PART 2 The big city saw your work on the small town library and now they want to buy your system! You need to make a couple changes to do this: You must take the app from PART 1, clone it, and create a new app with the following changes: - you must now support many libraries - each library needs to have a branch name, address, and phone number - each library has it's own collection of different books, the collection for the whole library system is attached as a CSV file, which you will need to load in - when searching for a book, users need to know which library the book is at - if all copies of a book are signed out, users can put a "notification request" on a title; when a copy of the book becomes available, the user needs to be notified via email Deploy this as a separate app on Heroku; send me a link to the app, as well as a link to the source on git. He told me implement this two projects in less then 8 hours.
