Form3 Take Home Exercise

Engineers at Form3 build highly available distributed systems in a microservices environment. Our take home test is designed to evaluate real world activities that are involved with this role. We recognise that this may not be as mentally challenging and may take longer to implement than some algorithmic tests that are often seen in interview exercises. Our approach however helps ensure that you will be working with a team of engineers with the necessary practical skills for the role (as well as a diverse range of technical wizardry).

Instructions

The goal of this exercise is to write a client library in Go to access our fake account API, which is provided as a Docker container in the file docker-compose.yaml of this repository. Please refer to the Form3 documentation for information on how to interact with the API. Please note that the fake account API does not require any authorisation or authentication.

If you encounter any problems running the fake account API we would encourage you to do some debugging first, before reaching out for help.

Submission Guidance

Shoulds

The finished solution should:

Be written in Go.
Be a client library suitable for use in another software project.
Implement the Create, Fetch, and Delete operations on the accounts resource.
Be well tested to the level you would expect in a commercial environment.
Contain documentation of your technical decisions.
Be simple and concise.
Have tests that run from docker-compose up - our reviewers will run docker-compose up to assess if your tests pass.

Should Nots

The finished solution should not:

Use a code generator to write the client library.
Use (copy or otherwise) code from any third party without attribution to complete the exercise, as this will result in the test being rejected.
Use a library for your client (e.g: go-resty). Libraries to support testing or types like UUID are fine.
Implement client-side validation.
Implement an authentication scheme.
Implement support for the fields data.attributes.private_identification, data.attributes.organisation_identification and data.relationships, as they are omitted in the provided fake account API implementation.
Have advanced features, however discussion of anything extra you'd expect a production client to contain would be useful in the documentation.
Be a command line client or other type of program - the requirement is to write a client library.
Implement the List operation.

We give no credit for including any of the above in a submitted test, so please only focus on the "Shoulds" above.
