Tge other reviews on the site are accurate. There are 2 technical interviews and they ask you about your projects and tangential questions that you should be able to answer if you were an active member on the project. The biggest piece of advice I can give you is to be honest. If you don't know something, explain your thought process and why you think X could be a possible answer. They want to know that you understand how to think, not that you can get the answer 100% right.
