Backend Interview Problems

This directory contains two sets of problems in two subdirectores called json-manipulation and mystery-duplicates. Each contains its own README.md file which explain a set of Tasks you need to complete.

Fork this repo and complete all of the Tasks described in the subproject README.md files, so we can see your solutions and git usage.

Running the sub-projects

We recommend you run these using IntelliJ. Open this directory in it and it should automatically have both sub-projects in the Run Configurations list in the dropdown on the top right of the project window, by the build and run icons.

This is how we will test your solutions!

Via the command line:

Assuming you've installed JDK12 and Gradle 6+, you can invoke Gradle directly by doing gradle :mystery-duplicates:run or gradle :json-manipuation:run on the command line.

Please Note:

This repo is configured to use IntelliJ as it's an industry standard but you're not required to have or use any monolithic IDE. Gradle, which is a free, multiplatform command line build tool, will run everything just fine as described in previous paragraphs. Whatever you're comfortable with, so long as the code works: nothing presented here is meant as a "trick."

If you choose not to use an IDE, you'll need java12 installed as well as gradle 6 command line tool. On OS X you can do that by running brew install gradle. Just remember that you can download intellij community edition for free from https://www.jetbrains.com/idea/download/

Further, one of the reasons we ask you to schedule a block of time with us is so that we can be available to answer questions! If something seems hard and doesn't feel like it should be, don't hesitate to reach out (though we might take five or ten minutes to reply.)

Hints

• Check ai.brace.EmployeeProcessor in the mystery-duplicates project for an example of how to load the lines of a text file from the resources directory.
• Google's GSON library is already included as a dependency in the root build.gradle file's description of the json-manipulation sub-project. It should automatically resolve when imported properly in that project.
