Over the phone. Very comfortable. Starts with intros and goes into structured interview with set questions and finishes the interview with time for candidate to ask questions about job.
like most standards interview questions to go through the recruiting process. Be prepared is always the key. If interview goes well, the offer process is fast and simple onboarding as well.
I applied online. The process took 1 day. I interviewed at Walmart (Tucson, AZ) in Jun 2015
Interview
2 people were on the panel and i was asked situation questions like the most difficult person i have dealt with and the most challenging project that i have undertaken. Also i was asked about the travelling option if i am willing to travel or not.
