I had a first interview with a HR guy and someone from QA department. It took around 30 minutes and it was more about my general experience (overview, that tools I've used, etc). For the second interview which was a live coding session, I had to code a FizzBuzz test. Once I was done they changed the test a little bit (FizzBuzzRazz, see below) and asked me to refactor the code. However, the interviewers made a mistake with the requirements for the second exercise and it took me a little bit more to figure out there was something wrong. They said I was right so they updated the requirements and I finally completed it. However after waiting for a week they replied saying that I haven't been selected for the role without any reason. It was weird and not very professional.
