There are 4 steps of interviews and you will go forward to the next step if you passed the previous one. 1. Take home project 2. User interview 1: coding problem solving (pair programming) 3. User interview 2 and 3: build an iOS app (pair programming) 4. Chat with CTO If you pass all the process, you will have a discussion with HR. Good interview experience where feedback is given and I also learned from the interviewers.
