r1| cashflo | sde 2
Summary
I attended my Round 1 interview for an SDE 2 role at Cashflo, which primarily focused on system design challenges related to read-heavy systems and S3 encryption policies, along with a graph problem.
Full Experience
This was R-1
Suppose when lot of loads come in service throws 500 error , but works for thre single request.
We have a read heavy system with postgres and redis, Design the strategy.
S3 encryption policies.
Graph https://leetcode.com/discuss/post/483660/google-phone-currency-conversion-by-anon-upqo/
Answer to first was resource exhaustion happened may be horizontal scaling, it was more on thread pooling or memory leaks and how to manage them.
read heavy systems use cache-aside read.
