Phone screen - basic STAR questions
Final round onsite interview - Full day affair, two ~45 minute interviews, difficulty completely dependent on the interviewer. My first interviewer asked me to design a class to fit a specification and include a few methods to do various things. My second interviewer asked me questions that no entry level software engineer would know. Things like maximizing uptime of an API using backup servers, how specific web browsers interact with HTML and their requirements, etc.
