Recruiter call aligns role and experience. Technical screening tests coding (DSA + practical tradeoffs). System design is critical—design large-scale, real-time systems (feeds, messaging, analytics), focusing on data flow, scalability, and tradeoffs. Strong candidates emphasize production-ready thinking, high throughput, and clear architecture decisions over textbook answers.
