Great interview process. The recruiter was very responsive, and the engineers were very good at communication.

Composed of an online assessment with 4 timed questions. These were a mix of easy/medium LeetCode questions. They stated the screen was monitored and a webcam was required, but you could Google documentation on a language, just not Google answers.

Next is a "Power Day" with 4 rounds:

1. Algorithms
2. Systems Design
3. Behavioral
4. Case Study

1. 3Sum variant: find a pair that sums closest to 0.
2. Systems Design: Design a smart meter system for a residential complex.
3. Behavioral: Standard STAR interview questions that focus on your past work experience.
4. Case Study: Mix of technical/business material. Honestly, this is a piece of cake if you can debug code and provide improvements at a basic level.

I was most scared of the case study because I didn't know what to expect. But basically, some things that are wrong with the code include incorrect looping conditions, using poor data types (e.g., when running a loop 10 times, they use a long data type instead of an int – you can suggest an int to save on memory), and analyzing how methods would run depending on varying input being passed in.
