When you interview for the profile of a cybersecurity professional the interviewer will get into the technical bits to establish your level of expertise once they finish asking you about your professional experience, educational details, and more such obligatory questions.
Now, how technical they can get depends on the position of the job profile you are applying for as a cybersecurity professional. But in any way as a cybersecurity professional, you are expected to be well versed in your field of work.
