I applied through an employee referral. I interviewed at Walmart (San Bruno, CA) in Jun 2017
Interview
2 phone interviews. One basic behavioral questions and the other had a market sizing case. Got in-person interview schedule with 6 interviews back to back (45 min each). All were mainly case based interview.
I applied through an employee referral. The process took 3 weeks. I interviewed at Walmart (San Bruno, CA) in Jan 2016
Interview
There was a recruiter that got in touch and related my experience to the job, told me about the job and set up a time to meet the hiring manager for the department they were looking for. After a short interview with the hiring manager, I had 3 back to back interviews within a week. They were looking to hire fast and I was the last they interviewed (I believe) so I knew the result within a few days and started 2 weeks later.
