How many rounds is the Substack interview?
Substack's loop usually includes a recruiter or phone screen, one or more technical rounds (coding and/or system design), and a behavioral round. The exact number varies by role and level; accepted-candidate experiences show the specific Substack loop.
How hard is the Substack interview?
Substack interviews are competitive and skew medium to hard on coding and system design. With targeted prep on the questions Substack actually asks, plus the round structure, they are very beatable.
