Interview Preparation: Questions, Rounds and What Actually Gets Asked

287 articles in this section.

This is the largest section of the blog, and the one that needs the most context before you use it. Each guide covers one employer: the interview rounds that company runs, the kinds of questions reported for its data science, analytics and business analyst roles, and worked answers for the technical parts.

Two honest caveats. First, interview processes change, sometimes within a quarter, so treat any round structure as a starting point rather than a guarantee. Second, where a question set is reported by candidates on public sites we say so, and where a question is a standard of the discipline rather than something specific to that employer, we say that too. We would rather tell you a page is partly generic than let you walk in believing you have inside information.

If you are preparing broadly rather than for one company, start with the SQL, Python and statistics guides in Learning Guides, then come back here for the employer you are actually interviewing with.
