Automation and robotization are a trend of the last ten years. In the case of HR, technologies help to automate routine processes such as document flow or candidate selection, process large volumes of data, and analyze employee performance. But as in other areas, in HR with the introduction of technology, everything is not so simple. First of all routine tasks which do not require creativity, creative thinking and deep analytics are automated: various calculations, construction of graphics, creation of statistics, accounting, personnel record keeping, filling of references. The trend will capture new aspects: from video interviewing to automatic calling of candidates. Automation saves employees' time and sometimes helps reduce the HR department. It's also common to automate data storage and management so that data can be easily found and structured. Most technologies are suitable for mass recruitment, if you need to hire ordinary employees with average qualifications. A "manual search" is needed to hire highly qualified specialists or managers on a point-by-point basis. There is an opinion that the introduction of technology is costly, time-consuming and difficult, and people continue to work the old way, from the principle "it works - don't touch". Many systems for automating recruiting and HR Departments are simple to integrate - you can move to them and transfer data from CRM or ATS (Applicant Tracking System, a system for managing applicants) in a week. Integration takes longer if the system is complex: you have a lot of data and business processes. There are also cloud services - they are already set up and do not require the organization of infrastructure in the company. You can do without HR automation if the company has a few employees: 5-10 people. In other cases, the business pays for not innovating with working hours of HR and recruiters who waste time on routine, inability to track hiring processes and make decisions based on analytics rather than intuition. Recruiters use different tools and services: ATS for recruitment, email, calendar, job sites, sourcing services, 1C and others. Recruitment automation systems need to be able to integrate with all the services and programs you need, without having to copy data from one to another. Any developer understands that working with integrations is a complicated story, any uncoordinated change on the other side causes everything to break. On the one hand, it's important to maintain integrations with all these services, to make sure they work. On the other hand, you have to give ample opportunity to other services to integrate with a particular service. That's why it's important to develop APIs.
