I have to study my field & areas of knowledge IN-DEPTH before EVERY SINGLE interview.

They ask me test knowledge questions, success stories and details about what I've done to resolve let's say for example, technical issues on an ecommerce enterprise level website. Or, how exactly did you increase traffic for this one website, mentioned in your resume, and tell us the methods used. Or how do you optimize articles for SEO? Or, what are the latest Google algorithm updates and how do they affect SEO strategy? Or, tell us about an off-site linkbuilding strategy you used that worked well. Or, what are the upcoming trends to look out for, and how have you prepared for those in your work? I have to answer questions about what is included in a technical or on-page website audit - and I have to answer these in detail and 100% accurately.

It's not like interviewing for a teaching role. I have to have all of these types of answers at my fingertips for every single interview I conduct. I tailor my answers based on the employer's area of expertise.

I spent SIX-EIGHT hours prepping for my last interview.

And, yesterday's interview involved a question along the lines of: what would be your long-term strategy for a site of several thousand pages, that is a new website with no domain authority, and what would be your short-term strategy?
