The entire process took about 2 months, from the first interview. My first-round interview was actually the most technical, where I was asked to explain "basic" cs concepts, based on my resume. The second, and final, round consisted of 4 different interviews. Every interview was casual and enjoyable. I was asked a variety of behavioral and product-related questions. Be prepared to talk about your past experiences with products or projects. Interviewers want to understand your thought process and how you solve problems. The most important thing is to just be yourself!
