ARN developer test -https://www.alliancereservations.com/developer-test.html

Requirements: You must be a U.S. resident living in the continental United States; do not apply otherwise. In C# create a single class that when subclassed allows this sample test code to run using only the file system for storage, no pre-built database allowed; use files. Create all classes required to compile and pass the test case; you may not modify the test. The test is not wrong, it's not a trick. The Id, Save, Delete, and Find methods must be in the super class only; subclasses must not implement these methods themselves. Use nUnit 2.6 as newer versions lack some of these asserts. Do not put your solution on Github, or a zip file, or an attachment, code is just text, email handles text just fine; you can submit the code in the body of an email as plain text. We're interested in the classes you create, not in build-able solutions or projects.

Choose whatever types you feel appropriate, the purpose of the exercise is to see some of your code and discuss with you the solution you if you make it to an interview. Your resume will not be looked at without code that passes this test. Submit your code along with your resume to jobs@allresnet.com. If we like your solution, we'll contact you to continue the process.
