Hi All,
Recently gave interview of NetApp.
First Round (filter): Interviewer discussed around the past experience and projects. Then gave a problem to solve ( can use local IDE or web).
Need to fetch all users from the open endpoint https://gorest.co.in/
and see which all users have posted more than x number of posts.
So Basically need to call 2 API endpoints and get the result.
Second Round : Completely on past project. Interviwere deep-dived on one of the project and wanted to understand my contribution.
Third Round: on DSA
Design a time-based two-tier storage structure that:
- Input: Accepts objects with (Key, Data) pairs to store.
- Storage:
- Buffer 1 (B1): Fixed-size Buffer of capacity N. New objects go here first.
- Buffer 2 (B2): Unlimited-size Buffer. Objects move here when their TTL expires.
- Time-to-Live (TTL): Each object has a TTL. When an object in B1 reaches its TTL:
- It is moved from B1 to B2.
- B1 must not exceed capacity N (decide behavior if full).
- Retrieval: Implement get(Key) that:
- Finds the key in either buffer.
- Returns the associated data (or null if not found).
- Should be efficient. - Should Reset the TTL when accessed
