Ericsson interview questions

I had an initial phone screening, and the next round was supposed to be a technical round. The person who took the second round only asked about my previous work and asked no questions apart from those. The third round was with a senior engineer. Here comes the most fun part, he was supposed to understand candidates and need to know what we know. but instead, he assumed when I mentioned a project I did by saying 'Oh that's all available online' But to the fact I had developed a model from the core with added features and I have developed a separate model with lots of verification techniques which is quite new in the image processing field. He had no patience at all to listen at least what I know instead he assumed and tried to insult the knowledge of the candidates. Not professional behavior I would say and He is from different background and was seeking the textbook definition answers. I was expecting much for the sake of the name Ericsson by the least. As far as I know, this is my worst experience. After this person, I never reached them back and would have declined even If they have reached, but fortunately with the Naive judgemental personality I didn't get the opportunity to give them the feedback too. Please Use the right people with a better mindset Ericsson!! Don't waste your time for the branch at Sweden, Ericsson-Worldwide. These are the worst People to interview any potential candidates. I read similar reviews before the interview but was optimistic thinking it might be improved/different for me. But no people! It was a total waste of my time.
