Interview Questions for Recruiting Experienced AngularJS Developers

 

AngularJS is one of the most popular JavaScript frameworks available today.Choosing the right AngularJS developer is essential to your organization’s digital progress. The right talent can be pivotal to your software development team. If you find the finest of developers, you can succeed in securing the top development team.

Recruiters are struggling to find right talent in the field of Angular technology. Sometimes they are unfamiliar with best sourcing and screening tools or just stuck with technical interview questions. They could not decide on what interview questions to ask to properly evaluate knowledge of Angular developer.

Here, this article offers a set of insightful questions to help you identify amazing AngularJS developers who are experts in their field.

Before jumping in the questions, let’s take a look at what skills you should look for in an AngularJS developer and in case you want to leave things to professionals you can use our Angular JS Online Test. Interview Mocha also has a vast library of 1000+ other online assessment tests that can be used.

Must have AngularJS Skills

Below are the must have skills you should look for when hiring an AngularJS developer.

Proficiency with JavaScript, HTML, and CSS.

I know this is obvious, but if you want to hire a great AngularJS professional he/she needs to know JavaScript and HTML. The efficiency with JavaScript ensures better performance and a cleaner modular code structure. He/She should be well-versed in the best practices that are critical to building AngularJS web applications properly.

Good understanding of MVVM and MVC.

If you want to hire a professional AngularJS developer, he must know MVC/MVVM model, design patterns. The candidate should have a good grasp of -

  • Separation of concerns
  • Data binding
  • Command binding
  • Validation
  • Unit testing

Build an App.

Ask whether the candidate has built an app

This implies that this candidate is much more valuable than someone who says they know AngularJS but hasn’t actually built anything. Ask questions in details here

Strong Communication Skills.

Lastly and maybe most important. An Angular developer might very well become the main communication node of your team. They will need to constantly cooperate with the back-end team, the HTML coders, and the designers. See whether the candidate can explain technical concepts effectively to coworkers, and less technically savvy clients.

Make sure your AngularJS developer is an outstanding problem solver with communication skills who is capable of taking your applications to the next level.

Human civilization has had technological advancements one after the other over the years. These advancements have taken over the recruitment industry too. The recruitment industry has come a long way, refining and making its recruitment process more advanced and easier for both candidate and management.

Recruitment Trends To Expect In 2020!

In recent years the recruitment process has evolved and continues to do so! It is all about data-driven recruitment now, with a pinch of human emotions! Many new trends came in the recruitment industry over the past couple of years, years pass and trends change!

Employee Engagement Trends to Watch for in 2020

In a landscape full of expensive work laptops, catered lunch, and other fancy benefits, engaging employees today is harder than ever. Despite these perks, however, the New York Daily reports that 70% of US employees are miserable at work. This is a large indicator of how leaders are still having trouble stimulating engagement with today’s employees, which is a workforce more diverse and younger than ever before. As new developments in technology and social norms occur at such a rapid pace, keeping up with the changing workforce and knowing how to engage employees can get a little difficult. That said, we’ve outlined a few ways you can stay ahead and have listed the incoming employee engagement trends of 2020. Be sustainable The millennial generation, who are in-line to be the next executives, want to work for companies who are sustainable — and the numbers don’t lie. A survey conducted by Swytch found that out of 1,000 employees, 70% are more likely to work for a company that has a strong green footprint, with 30% leaving a company due to not having a corporate sustainability agenda. Fortunately, it’s not that hard for companies to adapt — even using renewable energy is something that most companies can do, as it’s not as hard nor as expensive as it was before. In fact, thanks to decades of improved technology, Marcus notes that it's cheaper than ever to generate power from a solar grid. This is mainly because the cost to make it has lowered, making it possible for solar-powered projects to thrive, and companies to get into sustainability. While it isn’t meant to be a marketing scheme, being sustainable also provides an opportunity for outward marketing and branding as well. Offer remote or flexible work schedules Today’s generation highly values a work-life balance, and by offering remote or flexible work options, you’re fostering a culture that values these principles. This will increase employee retention as they see their employers value the same thing they do. Not to mention, quality of work and productivity will increase as granting them control over their time lets them choose the work times and environments that are best for them. If you want to start offering flexible work schedules, transitioning isn’t as hard as you think. Our article on ‘5 Ways to Effectively Improve Employee Engagement’ explains that you can start by offering telecommuting days, which lets employees work from home for 2 or 3 days a week. Download time-tracking tools and messaging apps such as Slack or Microsoft Teams to make collaborating and transitioning easier. Remember to also train managers to handle their new team of remote/flexible workers, as managing a flexible workforce isn’t the same as a traditional one. Provide opportunities for growth With the current technology, employees have an easier time developing their skillset — but they don’t want to do this without an opportunity to grow. Providing employees a clear path for growth along with some guidance will make them more motivated to reach higher and engage with the company. Without this, employees will become stagnant or feel demotivated as there are no goals to reach within the company. That said, make sure to pair your employees with mentors, or let them know about the next step in the corporate ladder and how to reach it. Provide seminars, give them challenging tasks, and let them have more opportunities to grow through conventions or events. An employee who feels like they’re valued by a company enough for the company to invest in their growth is an engaged one, and there’s no better way to do this than to give them opportunities
