I applied online for 2018 University Grad - Full time role (Software Engineer). Total duration of the process was 2.5 months. After getting selected, it took 2 months to match with a team. First was online assessment with 3 questions (1hr duration) - medium level difficulty. Followed with 1 HR round (mostly behavioral) and 1 coding round with a team member (only technical), both lasted for 1hr. Third round was held at New York office, an onsite round. It had 2 rounds, one with a manager and 1 with the team member. I liked the hiring process of McKinsey, as they were quick with their decision after every round.

Phone interview that lasted about an hour and a half, a developer at the company told first gave me a background of the company and its operations and asked about my background and preferred development languages and tools. Based on these he presented several situations including frontend, backend and devops challenges and asked how I would address them
