Nokia Research and Development Engineer interview questions

It started by taking a technical exam. The following week, you are expected to appear in a technical interview with the manager. When I arrived for the technical interview, my employer was 35 mins late. The last interview will be about your behavior. I answered the questions very well since most of the questions are easy. The manager said that I should expect a call the following week. 2 weeks have past and not a single call/email update has reached me. I tried to contact the HR but there was no response. So I asked a favor from one of my friends working there to have an update to my job application status. It turned out that I was not chosen over others. I wasted my time waiting. Some of my friends working there also said that most of the time, the HR there are INEFFICIENT.
