It was just 2 interviews. First interview was with 3 people: the cofounder, marketing, and an Android developer. They just asked about my experience and background as a developer. Second interview was with 4 people: the founder, cofounder, an iOS developer and the lead developer. It was almost the exact same as the first but they offered me the job in the second interview. I wasn't given a take home challenge or any coding challenges. I got the job based off the projects I built on my Github page and they liked my personality.
