Two lasting 1.5 hours and the last one is just half hour with the hiring manager/director

2 rounds of phone interview and 2 hrs of onsite interview with a principal software engineer and Director. first couple of phone interview were covering all the basics and coding over coderpad like app. It was easy to moderate.
