Challenges to Hire & Access MERN/MEAN Stack Developer 

Challenge #1 - Misaligned Expectations

Hiring & assessing managers think that a full-stack developer can work on all programming languages. But the fact is that various stacks need specific technical expertise or knowledge of specific elements.  

Here are most popular stacks and their technologies; 

  • MEAN Stack includes MongoDB, Express, AngularJS & Node.JS.  
  • MERN Stack includes MongoDB, Express, ReactJS & Node.JS.  

Challenge #2 - High Demand and Competition

MERN/MEAN stack developers are in high demand because of their ability to work with popular technologies. As a result, there's a lot of competition among employers seeking to hire skilled developers.  

Challenge #3 - Shortage of Experienced Developers

Since MERN/MEAN stack is a relatively new and rapidly evolving technology stack, there might be a need for more experienced developers with a proven track record. Finding developers with substantial experience in these technologies could take time and effort. 

Challenge #4 - Lack of Standardization in Skill Evaluation

Since the MERN/MEAN stack is relatively new, there might need to be well-established and standardized skill evaluation methods. It makes it difficult to assess a candidate's proficiency accurately.  

How to Access & Hire the Right MEAN & MERN Full-Stack Developer  

Here are a few steps you can follow to access & hire the right programmer for your MEAN/MERN full-stack development project.  

Step #1 - Create a list of your requirements

Before hiring & accessing MEAN/MERN stack developers, list your project's requirements and success metrics.  

It'll help you find a talented developer with the required expertise.  

Step #2 - Select the right hiring model

With the right hiring model, you can find the experts you need for your project. Here are two main types of hiring strategies; Outsourcing & IT staff augmentation.

Step #3 - Check technical skills

 A MEAN/MERN full-stack developer should be versed in technical skills & programming languages; 

Frontend languages;  

  • HTML and CSS to build web development solutions.  
  • JavaScript & JS frameworks like React, Angular, Node, and Vue to create dynamic web interactions.  

Backend or server-side languages; 

  • Java, PHP, Python, Ruby, etc 
  • Web architecture and APIs for backend development 

In addition, make sure your hired experts must have comprehensive knowledge of database technologies.  

Step #4 - Give Some Space for Soft Skill Assessments

Like technical skills, soft skills are vital in delivering a successful project. It’s essential to take soft skill assements when hiring a full-stack developer whether MERN or MEAN.  

 Here are common soft skills a full-stack developer must have: 

  • Open-mindedness & flexibility 
  • Integrity 
  • Creative mind 
  • Agile decision-making 
  • Ability to communicate and lead 
Step #5 - Make Practical Assessments through a Project

 It’s the best practice to assess technical skills when hiring software developers for your tech team. While algorithmic programming tests are a popular way to gauge skills with specific frameworks and languages, they don’t exactly provide a big picture of full-stack skills.  

For that, coding tests that mirror real-life tasks are far more effective in assessing candidates’ problem-solving capabilities and predicting their on-the-job performance. 

A coding skills assessment should also provide insights into their ability to solve the real-world problems they’re likely to encounter in their roles. Coding assessment tools like CodinGamePlatform and GLIDERai make your job easier and faster. 

Questions You Must Ask in the MEAN/MERN Full Stack Developer Interview 

You can understand the candidate’s skills, qualifications, and capabilities with a few questions. It’ll help you find the right fit for your project. Here are several questions you must ask from MEAN/MERN Stack developer during the interview: 

  • What are the key features they have for SEO when building a web app? 
  • Which development approach do they want for such projects? 
  • How do they fix bugs? 
  • How do they handle continuous integration? 
  • How can they protect a website from being web-scraped by a publicly available API? 
  • How well-versed are they in UI development paradigms like Bridge and Observer?
