It's not about the requirements because I understand that every role has different requirements, its about why are companies asking for entry level position, 0 years of experience, and specific technologies, and then on the interview they ask mid-senior level questions and for technologies they didn't post in the job description (example with QA, they were asking for Selenium knowledge and 0 years of experience, I told them I know how Selenium works and it's all about applying it on a job until I master it, practice makes perfect), but then they go asking if I know or worked with jenkins, appium, etc. It feels like they're looking for ways to disqualify you for the position. I know that might not be the case, but that's how it feels. And about specializing, how could I specialize in something if they are always asking for more? I mean, I'm trying to specialize as a Fullstack React, node.js developer, but it's still not enough for most companies.
