Hi,

I had my 2 coding screening rounds with Snowflake on 04/30.

Coding Round 1 - The input was a stream of log entries where each entry had details like seq no, user_id, Operation Type and other such details. Was asked to print the output stream filtering out the entries in the stream where the Operation type was DELETE.

Implemented using Hashmap to store, filter and print the output. Was asked couple more questions around how we could expand this to production and few more java questions around scaling.

Coding Round 2 - Was asked the currency exchange question which is found on multiple LC Discussions. Suggested implementation using DFS and was probed asking why i was choosing DFS and why couldn't we use BFS. Implemented it but the interviewer was a little persistent on how we would be passing in, the input to the function. At the end, implemented it but was stuck for a while.
