The eJPT was my very first certification. And I can really recommend it to every beginner. As already mentioned, the course material (without the videos and labs, though) can be obtained for free. The content is, in my opinion, very beginner friendly, and covers a lot different topics. Together with the labs, you can learn your basic ropes, and start exploring more specific topics that meet your preferences.
The certification exam will make you perform a simulated penetration test, starting with nothing more than a PCAP. From there, you gather information about the target network and will then be able to dive into the infrastructure, compromising several services through the techniques you learned during the course. Back in my days, there were on real “surprises” during the exam, since everything that is needed, had been covered by the course and labs.
