Getting candidates to come into an office for interviews can be tiresome, costly and time consuming for both, the employers and candidates. And what if they have come all the way into the office just to realize they are not a good fit? On the other hand, many people do not prefer to have phone interviews, as it does not fully depict a person’s personality.

An online interview is an online research method conducted using computer-mediated communication such as instant messaging, email, or video. More and more companies are conducting online job interviews because it saves on travel, time, and can be less stressful than traditional face-to-face (F2F) interviews. It saves employers money as they don’t have to pay for candidates to travel to the office and it’s easy to interview right from home for the candidates.

Fortunately, the growth of video technology eliminates many of these issues. Besides, the technology needed to conduct online interviews has become mainstream, so it is a simple and effective way to interview candidates for employment. It enables an experience similar to real-life interaction while saving the time, costs and effort of bringing someone into the office, at least for an initial check. This makes the process simple, quick and productive for both parties.

WebRTC for Interviewing App Development

After a while, since the real-time chat technology pulled the global market value, WebRTC has become the common element that plays multiple roles in exchange for the best possible voice and video communications.

WebRTC stands for web real-time communications which are an HTML5 specification. It is a free, open, powerful, and highly disruptive cutting-edge technology and standard that provides browsers and mobile applications with real-time Communications capabilities via simple APIs. WebRTC leverages multiple standards and protocols including signaling, servers, data streams, STUN/TURN, NAT, UDP/TCP, ICE, SIP, network sockets, etc. and a set of plugin-free APIs that are supported by all major modern browser vendors on both desktop and mobile.

WebRTC brings a lot of benefits to the users and developers that were not available in previous communications and collaboration platforms. Its components have been optimized to the level which enables the development of rich and high-quality RTC applications for the browsers of desktop, mobile, and IoT devices, and allow them all to communicate via a common set of protocols.

Let’s examine some of the advantages of using WebRTC Development for an interviewing app.

It’s Free

First and the foremost benefit of WebRTC is that it’s a free and open-source project. It was first introduced in 2011 by Google, supported by, Mozilla and Opera, amongst others with the objective to deliver a standards-based, real-time media engine that will be free and resident in all available browsers. It is embedded in all the popular browsers with many free voice and video codecs available to download. Most importantly, it’s free for both, commercial as well as for private use.

Being an open source platform, it is maintained by a huge community of volunteer developers, agencies, skilled engineers, and many contributors who work extensively to constantly evolving and improving, add new functionality, create new extensions, release new versions, and solve challenges.

It’s Easy and Simple to Use

WebRTC is not just a free web-based chat server, it’s more than that. Unlike other interviewing platforms that require to open an account or download a platform before engaging in an audio/video conversation, WebRTC removes this barrier by providing a seamless and non-invasive way to connect and collaborate. Using WebRTC when communicating with candidates, clients and business partners are easier, simpler and often more convenient.

Besides offering the real-time communication service, it helps companies to automate online interviewing directly between websites and mobile applications. The exchange of the arbitrary data is possible between the browsers without having an intermediary. You can also stream peer-to-peer audio/video calls without the requirement of third-party integration to the web application and mobile applications.

You can create a multi-user video conference using WebRTC just by setting up a mesh solution, which involves each user establishing a direct, peer to peer connection with one another. You can scale up to more users by using multipoint control units (MCUs) and selective forwarding units (SFUs).

Independent of Platform and Device

WebRTC is considered to be game-changing in terms of communications standard with endless possibilities for innovation. It allows developers to write HTML5 code that can work on desktop as well as on mobile devices. It can easily be embedded in the browsers with any operating system and a web services application and can direct the browser to create a real-time voice or video connection to another WebRTC device or media server. It does this by implementing standard APIs from the W3C and protocols from the IETF.

Unlike Skype, WebRTC makes it possible to incorporate embedded real-time communication features directly into websites and mobile applications. It also allows access to other communication devices. For example, you can access the microphone of your device, the camera that you have on your phone or laptop or it can be a screen itself. Furthermore, you can record the voice, capture the screen, or take a picture of the user and then have it shared or recorded remotely.

This feature of WebRTC is very helpful for live video interviewing. It enables browser-to-browser applications for video interviewing and allows more one-on-one interviews on the go, as it strengthens the quality of mobile video communications and offers capabilities for mobile devices like laptops and iPads.

Innovative Recruitment Solution

WebRTC has helped to fuel the evolution of recruitment solutions to HR technology. It is a highly scalable and enhanced solution to HR problems. It allows developers to build an interviewing application that allows up to six interviewers at the same time. Which means it is six times faster than the traditional interview platforms. It is also equipped with many other features that enhance the recruitment process even more. For example, it offers archiving and playback options. You can also enable interviewers to take private notes or have a chat while applicants are talking without requiring the help of any software downloads or plugins. Companies can also feature their logos and branding on the screen throughout the interview session, making the session more professional.

Market Impact

It is important for a company to keep up with the industry trends and the latest technology to showcase its relevance and awareness of what’s happening around. Real-time communication is becoming the norm across any industry and that’s what as a company you should be working on. The HR departments must keep in mind the types of candidates that will be joining the workforce. More often, the candidates are tech-savvy. They expect real-time interaction, feedback and access, and not just the recruitment process.

WebRTC, with its multi-faceted communications capability, can provide several different forms of communications that have a significant impact on the job market. Candidates want to be able to use it. With its ability to provide web-based chat, HD-quality audio and video makes connecting in real-time easy and efficient for those candidates who want to contact companies. Also working with video interview platforms and solutions saves time and money.

Fast, Easy and Cost Saving

When it comes to the benefits of using WebRTC for building audio/video chat enabled application, it’s no surprise that the WebRTC goes beyond its technical and architectural benefits, it also provides cost-saving benefits to the world on a real-time basis. If you were to build an application that allowed audio/video calling a few years back, you were most probably be using C or C++ for that. That means longer time for development resulting in higher development cost. On the other hand, you can use multiple programming languages, database & OS such as peer.js, JavaScript (Node.js), which are faster, lighter, efficient, and easy way to build WebRTC audio/video chat app for Android, iOS & Web. This also acts as a run-time environment in developing WebRTC applications, which is a perfect model for data-intensive in a real-time application that runs on across multiple distributed devices and performs seamlessly on multiple platforms.

Furthermore, WebRTC can even offer reduced business costs when used as a supplement to remote meetings, interviews, and conferences. Through a peer-to-peer connection in delivering real-time audio/video chat functionality across multiple browsers and platforms. It can eliminate at least some business travel, which can be a huge expense for some organizations. Plus, WebRTC systems can serve many of the same purposes as some of the other interviewing apps, but for significantly fewer expense thanks to the ease of deployment.

Advanced Voice and Video Quality

Among the other benefits of WebRTC is also included the fact that, particularly due to the adjustable built-in microphone settings, this technology provides better sound quality than Flash. WebRTC uses the Opus audio codec which is based on Skype’s SILK codec technology that produces high fidelity voice. Similarly, it uses VP8 codec for video transmission. These selections ensure interoperability and avoid the need for codec downloads that may contain malicious code.

WebRTC with its advanced adaptive network solution such as multiplexed RTP Control Protocol (RTCP) and Secure Audio Video Profile with Feedback (SAVPF) compensates and adjusts to changing network conditions. The receiving browser sends network condition information back to the sending browser where the conditions can be analyzed to respond to changed network conditions. It adjusts the quality of the communication, detecting and avoiding congestion. This also produces an efficient use of bandwidth, delivering the best possible voice and video communications.

Furthermore, WebRTC also supports reliable session establishment which reduces the server load by blocking other communications and collaboration protocols. The reliable operation avoids server-relayed media and thereby reduces latency and increases quality.

Secure Voice and Video

When it comes to browser security and stability against external attacks, WebRTC is certainly the best choice. WebRTC has an always-on voice and video encryption. This is accomplished using the multiplexed RTP Control Protocol (RTCP) and Secure Audio Video Profile with Feedback (SAVPF). The Secure RTP protocol (RTCP) is used for encryption and authentication of both voice and video. This is especially beneficial over WiFi networks. This prevents overhearing and recording of the voice and video.

Not only that it secures voice and video but you can also send massive files directly through your web browser using WebRTC’s data channel, Instead of emailing the file or uploading it to a third party cloud storage system, with the benefit of full encryption between the two endpoints.

Supported by most leading Web Browsers and Platforms

You can easily couple WebRTC with third-party apps like OAuth to pull data from services like Facebook, LinkedIn, and Google. These features also enable rich contextual communications which makes it possible to have a video interview where WebRTC’s data channel is used to send a stream of relevant and contextual data as an overlay to what’s seen by participants, complementing the live video chat. This could enable easy sharing of the person’s Twitter handle, email address, or other public profile information, along with links to their most recent tweets or Facebook posts.

WebRTC is mostly implemented using C/C++ library and comes with a Javascript API which is also supported by most leading Windows browsers, including Google Chrome, Opera beta, Yandex and Firefox. This makes it far easier to develop and integrate real-time communications anywhere including existing online business.

Conclusion

The bottom line is WebRTC delivers HD-quality audio and video communication and makes connecting in real-time easy and efficient. In addition to these benefits, working with video interview platforms and solutions saves time and money. Job seekers want to use it to get in touch with businesses, and businesses have a great potential to use it to contact other businesses and save big on business travel.

It allows browser-to-browser applications for video interviewing. It offers live video interviewing to both, employer and candidate and enables multimedia chat applications for desktop and mobile. As this technology grows, it’s going to offer more one-on-one interviews on the go.
