[Snowflake] [General SDE] Interview Experience
Interview Stages
Round 1: Coding
- Process: A coding interview focusing on problem-solving.
- Topics/Problem: First problem was similar to LeetCode 636, but with the added requirement to determine if the root node is the average of all subtrees. Followed by a quick question related to LeetCode 981, asking how to handle input not in increasing order.
- Focus/Signals: Problem-solving efficiency and understanding of tree structures.
Round 2: System Design
- Process: A system design interview with a unique problem.
- Topics/Problem: The question was derived from a past incident at Snowflake. It involved optimizing a client that periodically fetches a token from a third-party service to access the backend, aiming to minimize offline time.
- Focus/Signals: Ability to design efficient systems and handle real-world scenarios.
