Experience:

This detailed interview experience for a Software Engineer (IC1 / IC2) role at Snowflake was shared on Reddit. The overall process was broken down into several stages.

Initial Call: A standard sanity check call.

Technical Screening Rounds (2 rounds): Each round was a 60-minute virtual coding technical interview, often domain-specific. The format typically involved solving one Hard or two Medium LeetCode-style problems.

Full-Loop Final Interviews (Onsite/Virtual): This stage consisted of three 60-minute rounds.

• Round 1: Coding (60 minutes) - Similar format to the technical screening rounds, focusing on coding problems.
• Round 2: System Design (60 minutes) - This round was described as "infra-heavy" rather than product-style. The interviewer expected the candidate to think aloud while designing a production-grade service that could:
  • Scale under heavy load (e.g., horizontal scaling, auto-scaling groups).
  • Use reliable storage and durable queues for asynchronous operations.
  • Handle failures gracefully with retries, timeouts, and circuit breakers.
  • Be observable through logs, metrics, alerts, and dashboards.
  Observability and scalability were emphasized more than specific features.
• Round 3: Behavioral (60 minutes) - This was a deep dive into past projects, ownership, and decision-making. Specific questions remembered included:
  • "Why do you want to work at Snowflake?"
  • "What project are you most proud of?"
  • "Tell me about a time you disagreed with your manager."
  • "When did you miss a commitment?"
  • "Give an example of a time you took a calculated risk under pressure."
