Great interview process. Recruiter was very responsive, engineers were very good at communication.
Composed of an online assessment which has 4 questions and is timed. These are a mix of easy/medium leetcode questions. They say screen is monitored and webcam but you can google documentation on a language, just can't google answers.
Next round is Power Day with 4 rounds.
1. Algorithms
2. Systems Design
3. Behavioral
4. Case Study
Preguntas de entrevista [1]
Pregunta 1
1. 3Sum variant - find pair that sums closest to 0
2. Systems Design - Design smart meter system for 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 to 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 are incorrect looping conditions, using poor data type (e.g. when running a loop 10 times they use a long data type vs an int - you can suggest an int to save on memory), and analyzing how methods would run depending on varying input being based in.

Power day style interview, two coding, one system design, one behavioral. Everyone was nice, but the interviewers seemed a little under prepared and/or new to interviewing in general. Questions where essentially leetcode medium/hard almost word for word.

Code assessment then to power day interview with 4 rounds. Overall the power day interviews were okay except for the case study. The interviewer was disengage while being on their phone the whole time. There was a part where the interviewer said fix the mistakes then went back to their phone. I pointed out their code has other errors with template and was ignored. Then while attempting to fix those (10 mins later) they mentioned to ignore that part and focus on the very bottom part of the code. What a waste of time and very unprofessional. This makes me wager a few of the interviewers probably could not pass their own interview process today.
