I had 2 technical interviews, first with a random architect, he was awesome, cover a very well range of topics about general front end and some back end theory. He sometime correct the smallest detail of my answer, he is a very smart guy. Second with a future team member, he has a strong middle east accent, I tried to explain the complexity of my solution, but he seems doesn't understand what big(o) is. tried to explain performance issues, but he didn't care... used closure for factory to create auto-increment ids he said not to use closure... most questions are poorly asked or being too vague. zero questions about promises, prototype, inheritance, closure, angular... Really don't know what kind of team to expect...
