I was asked to visit onsite directly by the hiring manager. Had 3 different interviews with PM hiring manager and Lead developer. Few were technical, few asking about previous work ex in detail. Also asked about college projects and how I could benefit the team etc. We discussed about the work that was going on in the company etc.

Very informal, mostly a basic screening of developer skills over the phone, followed by a basic test with a 48 hour window to complete. No weird algorithms, just questions and a test designed to see how well you would mesh with the development standards within the company.
