Hire deeply-vetted Node.js/Raspberry Pi

Node.js and Raspberry Pi are two of the most popular technologies in the world today and the demand for Node.js and Raspberry Pi developers has been rising, making it challenging to hire these professionals. You need to consider various factors, including experience and skills in these technologies before making your hiring decision.

That is why we have put together an excellent resource to assist all the recruiters who aren’t familiar with the technical terminologies related to Node.js and Raspberry Pi. This will help you in filtering the best talent like a pro and help you hire Node.js/Raspberry Pi engineers who will fit your organization's requirements.

At a high level, you should hire Node / Raspberry Pi developers who have the following skills in their arsenal:

Node.js is a JavaScript runtime environment that allows developers to run JavaScript code on the server side. JavaScript provides a robust set of libraries and tools for building server applications, making it essential to understand JavaScript to work effectively with Node.js. A solid understanding of JavaScript's asynchronous programming features, like callbacks, promises to help developers leverage the technology efficiently. Hence, when you hire Node / Raspberry Pi developers, ensure they have a deep understanding of JavaScript as it is one of the core skills and is unavoidable.

Raspberry Pi is used for different reasons like hosting a website, using it as a desktop and for your own DIY projects, etc. This tiny credit card size computer uses the same working principles as the average computer at the expense of a very low cost. Therefore, try to hire Node / Raspberry Pi developers who know the ins and outs of Raspberry Pi’s sensor and software ecosystem.

Data plays a vital role in the functionality of an application which ultimately makes the database a crucial aspect of software development. It allows developers to store, fetch and manipulate data as per the requirements. So, when you hire Node / Raspberry Pi developers ensure they have experience and understanding of tools like object-relational mapping (ORM), Mongoose (for MongoDB), Typeform, SQL Databases Sequelize, respectively, and more. Additionally, you can also check if they understand the differences between relational and non-relational databases.

Raspberry Pi supports C/C++, Python, and Scratch by default. However, it allows developers to install nearly any programming language as required for the project. Although, experience with at least one programming language is an unavoidable skill for a developer. When you hire Node / Raspberry Pi developers, it is important to know if the applicant understands how to install Java, PHP, Rust, Ruby, and other programming languages and run an application.

The Node.js architecture allows developers to handle multiple concurrent client requests quickly and easily without needing to create multiple threads. Additionally, it requires fewer resources and memory to deliver highly scalable, customer-centric, and performant web applications. Therefore, try to hire Node / Raspberry Pi developers who can design, build & manage micro-services and back-end API for high traffic applications.

Today nearly every software application needs third-party integration to make the business operation efficient and error-free. Additionally, it offers companies to have only one source of data and eliminates any prospects of loss and misusage of generated information. Hire Node / Raspberry Pi developers, who know and make the most of these third-party services.

Creating a hiring funnel will provide you with numerous benefits, like assisting you in identifying the top skills to hire Node.js/Raspberry Pi developers who will fit into your company's culture.

Hiring for a new skill can be a daunting task even if you’ve been a part of recruitment processes for quite some time. But it is also critical to the success of your project that you hire Node.js/Raspberry coders who are the right fit for your team. So, if you’re looking for questions that you can ask to test the applicants, here’s a list that you can refer to.

Here are some more Node.js /Raspberry Pi developer interview questions that you can ask to assess a developer’s caliber.
