If you work for IT industry for more than two years as a recruiter, you can ask yourself a question- does “regular job offer” for particular position today is different than job offer for same position a few years ago? What about expectations of known technologies, about additional tools or infrastructure?
Of course answer for this question is yes. Technologies, methodologies and tools are different now than some time ago. You can expect, that in next two years they will change again. Probably some frameworks will be still in use (in new versions), some will disappear and there will be a lot of new ones. That’s normal situation- you need to get use to it.
When anybody starts asking you about technologies or anything tech-related it’s probably easier just answer that it’s not within your competences. But… using this approach you can lose some good candidates. Out there are a lot of similar technologies. Your client can ask to find someone with experience in Hibernate. Hibernate is just an implementation of JPA so you can check every candidate that have JPA in CV. Knowledge about these relations can boost your productivity. Lets be more aware of Java world!
