Business insights Analyst at YouTube

Any guidance in prepping or any pointers I need to keep in mind to crack the first Hangouts interview? I'm also interviewing for a Senior Data analyst position which according to the recruiter is much more technical than the former. My question is should I also prepare for Algorithms and Data structures even though it's not a developer role. I heard Google takes more of a generalist interview and I don't have a background in working with Algorithms. Just scripting. TC: 90k YOE <1 Thanks!
