I applied through a staffing agency. I interviewed at Walmart in July 2017
Interview
It was for a remote position... I met on a video call with the director of mobile, then 3 engineers. Some on the phone, others in a WebEx. It was very informal, and not particularly rigerous. I felt the engineers were not prepared to interview me, and didn't even have my resume in front of them (they only had a link to my Linkedin profile which was incomplete).
Interview questions [1]
Question 1
Mostly they asked high level Android questions, mostly pertaining to high-level framework questions. Nothing particularly in-depth, or challenging.
