I have been recruiting / interviewing people since I worked as a Senior System Administrator, it is not possible for HR admins to understand the level of experience a person has in terms of technology, I have been doing this on a part time / as required basis.
I have worked as a System Administrator / System Engineer and have worked with various technologies like Cloud (AWS & Azure), Docker, Kubernetes, Jenkins, VMWare, Linux & Windows Servers to name a few.
I can help you to determine a persons overall understanding of a particular technology, whether he understands what he is required to do and whether he would be a good fit for the role offered.
Do ping me if you need to hire a DevOps Enginee, Cloud Engineer, Linux Engineer, VMWare Engineer, Windows Server Engineer. You may hire me as a full time or part time technical recruiter, I prefer working remotely and can adjust my work timings as per the candidates timezone.
