Behavioral questions are the fucking worst and I despise them. If you're honest, it looks bad but you go for the standard bullshit answers and you look like you're just bullshitting. Interviewers who ask these types of questions are people you don't want to work for. ha
I actually haven't had one of those stupid "what is your weak point" or something like that in a long time. I one time had a guy who asked me what my friends would say about me if they were to describe me. I said "troll and prankster." Got the job. He later said that he took that to mean "crafty" and he liked it.
I also tell jokes, make fun of myself, and throw in some sarcasm. But I'm IT and IT people are cynical bastards.
I have found great success in interviews by just being flat out honest and the less desperate you are, the better you'll do. I've gotten offers when I just don't give a fuck, but when I really need it is when I start failing because I feel like I need to say the right things. Got an offer once with the contingency that I needed to change my hair. Fuck that. I declined. If they are concerned about hair, they reeeeally wont' like me.
So, I suggest being flat out honest even if the honesty is masked with some professional verbiage.
SEO is kinda marketing, a little technical and these fields are less uppity than something like finance. Of course, every interviewer is different. Remember an interview is not only for them, but it's also for you to determine if you'll make a good fit with their team.
