I was invited for a first interview, which we rescheduled a couple of times, as the manager was often out of the office. The interview was about 40 minutes long, with average difficulty. After that I was contacted for a second interview with another manager. We scheduled an interview based on my availbility, however the day before the interview I was asked again to reschedule. I agreed but I never got a reply. I contacted them again via email a couple of times after that, in order to ask whether we would move forward with the interview, but I didn't get an answer.
