I agree with the opinion, but not the timeframe. I would say the quality has nosedived over the last 8 years, based on my experience as the tech interviewer for potential new hire interviews across the last 12 years on different projects. The last 4 years I've gotten comments from co-interviewers of 'you ask the hard questions', 'you are tough'. These are in response to questions such as 'What are your thoughts on composition vs inheritance in object oriented design', 'What are the arguments for Java as a better language than Javascript? How about the other way around?', 'What's a progressive web app, what aspects of React and what react-related libs help with creating one?'. These were all directly relevant to the positions being interviewed, and some of those were for senior engineer positions. These are questions that I think should be answerable by any senior frontend engineer, and most senior software engineers.
