There are 7 rounds of interviews. The manager and skip-level manager conduct the initial screening and final interview.

In the first round, you'll answer general technical questions related to the job post requirements. The other five rounds cover:

• API maintenance
• Machine learning
• Domain-specific coding
• LeetCode coding (easy and medium)

The final round dives deeply into your most recent project to test your comprehensive understanding.

Given the formula for a specific signal processing algorithm, which is brand new to me, write a function to implement it.

(I forgot the name, but it should be just a little bit harder than implementing an image scaling function or a blurring function.)
