There was an offline test conducted before I had face to face interview. offline test will be creating some small project. I was interviewed in Potsdam location, where I had to face 3 rounds of interview. 1-> Technical (tip: Know your basics, Design patterns are important) 2-> Case study round( tip: Know your domain, I was asked to explain complete architecture of the previous project including hardware limitations and pros and cons of moving it to cloud) 3-> Hr+ manager round(tip: Be prepared for question on your notice, salary, expectations and motivation) each of these rounds lasted for 1 hour each.
