Asked lots of questions on front end development experience (UI design, user profiles, use cases). Also about experience with test processes and multi-threaded application development. Some basic tech screening questions like abstract classes versus interfaces. Seemed like most of the other questions I got were heavily opinion based (experience-based) and that the hiring manager was somewhat opinionated and not very welcoming.
