A series of phone screens (2) and an onsite interview based on the results of the phone screens. Typical process, HR was quick to respond with scheduling. The first phone screen covered basic software concepts/questions with a few verification related questions, the interviewer was on time, introduced himself, what his role was within the company and overall seemed organized; asking meaningful, job related questions. The second phone screen was the polar opposite. The interviewer was just under 10 minutes late, introduced himself, and asked "puzzle" type questions where the rules changed as we progressed. After asking the question, I could hear him typing in the background and at times respond "uh-huh..yeah"....even when I wasn't speaking. Very surprised given the reputation

They asked about past experience, C++ leetcode, digital design, and computer architecture. It's pretty structural and flexible based on your ability. Different interviewers might have different question sets. Good luck!
