EPAM Systems interview questions

Contact via Linkedin, video call interview, company description, everything good, and so on. The technical interview (1 week later) was not so pleasant, the interviewer asked questions via chat about the description and writing of blocks of codes or scripts, but the point is that, who today memorizes a code to answer or put everything together a script in a text box, live and direct, is meaningless and does not seem to me to be a real validation of the intelligence, capacity and abilities of an applicant. Also the interviewer, despite it being a video call interview, never showed his self, while I did, and I faintly heard a small laugh when I was trying to search in my memory for the code structure in the questions. I think, how is it possible to do a technical interview in this way, when nowadays tools like Terraform, Jenkins, Linux, Docker, Kubernetes... etc., give you access to command consultation while doing a certification, and in the same way they provide you with a code template either in Groovy, JSON, or YAML, to start a project. What was the interviewer trying to measure by asking about writing an entire script in a text box without even allowing the applicant to see the tool's documentation? Really a bad experience, and perhaps a disproportionately wasted time.
