The emergence of web conference technology and its usage has been enabling the most uncomplicated production of webinars and meetings. Being online, they are much easier to attend as well. Network, speed, and browsers are important players of this game.

The companies these days are highly inclined towards hosting webinars for training or sales. A new webinar is being hosted online every 1.5 weeks. Focus and engagement have become the most centric part, and so an average of 25 to 30 minutes webinar is proved to be sufficient as per recent research.

A significant change is also quite vigilant in the arena of job interviews. 66% of job candidates have opted for the video-enabled-interviews instead of wasting their time to visit the interviewer personally to attend the interview meetings.

Web conferencing has proved to make a conference call more interactive and added an option to enhance productivity. Live meetings and live training sessions with a PowerPoint presentation, an Excel spreadsheet, or something else has transformed with the Artificial Intelligence (AI) and Machine Learning (ML) principles. Highly sophisticated 4K resolution cameras, machine vision, virtual assistance, and facial recognition increase the effectiveness of meetings today. AI enables us to determine the optimum length of the meeting session, the ideal number of meeting participants, and the best time of the day to schedule the meeting to improve productivity.

Companies have now become more interested in hiring remote teams than hiring remote employees. Leveraging more on web-conferencing software solutions is saving cost, time, and resource. Virtual chat tools and video conferencing solutions for small businesses have made it easier for remote workers to feel as a part of the team.

The meeting is ideally organized to reach an outcome, and it better proves through what an expert once said, “With cuts to budgets, every trip needs to be justifiable. This time, it is a video conference: safe and budgeted”.
