Interviewed by the Head of Organic Performance and another senior person in the company.
One interesting aspect was that they were late to the interview (one would expect the same courtesy and preparation from interviewers as it's requested from the interviewees - even more so when the interviewer represents the company). Unprofessional, for sure.
The other aspect worth mentioning is that one of the interviewers called the person from the recruitment agency an idiot because he's sent them someone who wasn't interested in some particularities of the job. If he didn't care what I would think about something as unprofessional as this when I wasn't even on board yet, I imagine he wouldn't be quite the ideal manager to work under. I am only speculating, of course.
That aside, it was a fairly straightforward process altogether, with both of them being polite but quite stern and detached, like they were paying the bills. Expect the typical questions regarding SEO, have a look through the latest trends and developments in this industry, make use of tech lingo and mention as many of the specialist tools you're using as possible (if you remember them).
I was a bit surprised not to be asked about actual results obtained in the past - with live examples, and to do a little practical exercise to showcase my (potential) knowledge of G Analytics (filters, dashboard widgets, where to look for specific user behaviour patterns, free/paid campaign results), Search Console, analysing a live website and make recommendations (where possible).
All in all, it wasn't a bad experience, but slightly unpleasant.
