I was invited to a hiring event. I talked with a manager for 90 minutes, and it felt more like a conversation than an interview. At the end of our discussion, he said I'd fill out an online application as a formality and to expect an offer in about 3 weeks, which is exactly what happened. There were no questions designed to test specific technical knowledge, but we did discuss my technical abilities based on my previous experience. He was a fantastic interviewer and I enjoyed my experience.
