Capillary Technologies runs a four-round process: a written test, a technical round, a hiring-manager round, and a culture-fit round.
The technical round opens with low-level design or machine-coding (candidates report being asked to build small components like rate limiters from scratch), then moves into authentication design, SQL joins across relational tables, and basic Unix diagnostics (grep, find, ssh) to see how you'd triage a hung process. As a loyalty-and-CRM SaaS platform serving 250+ global retail brands, expect SQL questions framed around real multi-table reconciliation problems, not toy schemas.
