I was very quickly interviewed by the HR person over the phone, then a chat with the hiring manager was scheduled soon after. Both interviews went smoothly and both interviewers seemed very happy with the outcome of our conversations. No difficult or tricky questions were asked. The hiring manager did even tell me what the next steps would be, i.e. an onsite interview and a practical test to evaluate my skills. He said they were waiting for one of their colleagues to come back from abroad (the week after) in order to make it possible for the on-site interview to happen. After 5 months since the last phone call, I'm still waiting for their peer to come back, so we can move on to the next steps. Please, let people know if they're not considered anymore for a position. Of course, my feedback is negative.
