General Elastic Path Cortex API app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in Elastic Path Cortex API application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

How would you describe the role of Elastic Path Cortex API in e-commerce?
Elastic Path Cortex API plays a crucial role in e-commerce by providing a hypermedia-based API that allows for the seamless integration of e-commerce capabilities into any application, device, or business system. It enables the creation of unique, flexible, and scalable e-commerce solutions.
What are the key features of Elastic Path Cortex API?
Key features of Elastic Path Cortex API include hypermedia API, cloud-native architecture, flexible data modeling, multi-tenant SaaS, extensibility, and scalability. It also supports omnichannel operations and provides a unified view of customer data.
Describe the difference between RESTful APIs and Hypermedia APIs.
RESTful APIs are based on representational state transfer technology, which is an architectural style that defines a set of constraints to be used for creating web services. Hypermedia APIs, like Elastic Path Cortex API, go a step further by including hypermedia links in the response that clients can follow to discover more resources and actions, making the API more self-descriptive and navigable.
How would you handle versioning in Elastic Path Cortex API?
Elastic Path Cortex API uses media type versioning. This means that the version of the API is included in the Accept header of the HTTP request. This allows for multiple versions of the API to coexist, enabling backward compatibility.
What are the benefits of using Elastic Path Cortex API for e-commerce development?
Elastic Path Cortex API provides benefits such as faster time-to-market, flexibility in design, scalability, and the ability to create unique, tailored e-commerce experiences. It also allows for seamless integration with other systems and supports omnichannel operations.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with Elastic Path Cortex API.

What does this simple JSON object represent?
{ 'product': 'Shoes', 'price': 100, 'quantity': 2 }
This code represents a JSON object with three key-value pairs. It describes a product with the name 'Shoes', a price of 100, and a quantity of 2.
What does this JSON syntax do?
{ 'employees': [ { 'firstName':'John', 'lastName':'Doe' }, { 'firstName':'Anna', 'lastName':'Smith' }, { 'firstName':'Peter', 'lastName':'Jones' } ] }
This JSON syntax creates an object with a key 'employees' that contains an array of objects. Each object in the array represents an employee with 'firstName' and 'lastName' properties.
What will be the output of this JSON array manipulation?
{ 'fruits': [ 'apple', 'banana', 'cherry' ] }.fruits.push('dragonfruit')
This code will add the string 'dragonfruit' to the end of the 'fruits' array in the JSON object. The new array will be [ 'apple', 'banana', 'cherry', 'dragonfruit' ].
What does this JSON threading-related syntax do?
{ 'thread': { 'id': '123', 'status': 'running', 'priority': 'high' } }
This JSON syntax represents a thread object with properties 'id', 'status', and 'priority'. It does not actually perform any threading or concurrency operations, but it could be used to describe the state of a thread in a concurrent system.

Wrap-up questions
