Do note that these interview slates will vary depending on level of candidate experience.
At Google, we generally do not ask system design interviews of new grads / entry-level candidates. It's pretty rare for mid-level candidates (L4), and expected for senior and up (L5+).
Also, there are situations where candidates may have an extra interview added to their slate. One common reason for this: the hiring committee doesn't have enough signal because the interviewers don't coordinate appropriately, and end up asking heavily overlapping questions (e.g. 3 questions that basically reduce to "use DFS").
