Software Engineer (New Grad)
This is a demo case file: a realistic example written from commonly known interview formats, not a real candidate's interview experience.
Questions asked
- Given a list of meeting time intervals, merge all the overlapping ones.
- Given a grid of 1s (land) and 0s (water), count the number of islands.
What to expect
Two standard problems in a shared doc with no autocomplete. The interviewer gave a small hint on the second when I stalled, and seemed fine with that as long as I used it well. Walking through my own test cases at the end, including an empty grid, clearly counted.
