The interview process started when I was emailed by an HR representative to schedule an initial technical Interview. After passing, we scheduled another 3 rounds of back-to-back technical interviews. Each interview asked about resume experience, general domain knowledge (a lot of hypotheticals of how you would optimize or approach a specific problem), and then a coding question.
