The Online Assessment is the first round. It mostly consists of aptitude-based questions to gauge your problem-solving skills.
The Personality Round is a discussion about the different aspects of your personality, such as your work ethic, etc.
The first Technical Round is all about your expertise with the tech stack. As I was interviewing for the Android Developer role, I was asked questions about the fundamentals aspects of Android, Jetpack Components, etc.
The second Technical Round was more of a discussion between me and the Director of Product. We talked about things like my previous experience, my expertise with my tech stack, my potential role at the company, and such. We also discussed the tech team at the company, the products, what a workday at Intelehealth looks like, etc.
