I applied through university. The process took 2 days. I interviewed at Baker Hughes (New Delhi) in Sept 2018
Interview
They first take aptitude test then group discussion and then a combined technical and HR interview. They tend to mix the questions they may start with HR questions then quickly go to technical and then come back again with HR.
