I applied through a recruiter. The process took 4 months. I interviewed at NTT DATA (London, England) in Jul 2017
Interview
overall 4 rounds of interviews and 1 additional round if the salary you ask for is outside their usual range. most of the rounds were to assess you as an individual along with your attitude and technical capability. it was important for them to see if you as an individual were a right fit for the team and the org.
