Block

Interview process
With roughly 12K employees and headquarters in San Francisco, US, Block hires through dedicated recruiting teams, and loops at companies of this size tend to be structured, with each round scored against a written rubric. Interviewers are usually trained engineers and managers rather than the hiring manager alone, and candidates for backend engineer, database engineer, developer relations engineer roles typically face separate rounds for core skills, design or case thinking, and behavioral fit.
