I recently interviewed with Roku and went through two technical rounds:

Data Structures & Algorithms (DSA)
I was asked two questions, both of which I was able to solve. The interviewer ran few test cases, which passed.

https://leetcode.com/problems/max-area-of-island/description/
https://leetcode.com/problems/minimum-cost-for-tickets/description/

The interviewer was not communicative and said he was unsure about the recursive solution for second one so I discussed the dp approach for it but due to time constraints I was unable to code it

Low-Level Design (LLD)
I was asked to design a Grocery Subscription model. I laid out the necessary classes and entities and walked through a sample use case. The interviewer mentioned that he was able to follow my explanation.

Verdict : The HR said that the feedback was a mix one so they are not progressing .
