This actually goes to Karat, who conducted the phone screening.

Coding challenge: Similar to "Word Search" (LC79), but with one small change: we can only go either to the right or down.

Karat feedback: Candidate missed a core logic to keep track of visited cells!

But did I? Can we bite our tail if we only go right/down in a grid?

System design questions were like: We have a service that needs low latency of 20ms. Now! Eventual consistency or strong consistency?

Karat feedback: Candidate answered EC but did not point to the SLA!

How on earth do you know we even have an SLA to begin with?

No need to mention I failed!

Wayfair recruiter was kind and suggested to retake the test, which I passed.

You know what? I deserved it! I should have listened to others who had already tried Karat.
