After sitting on my resume for 3 weeks, both stores I applied to decided they needed to set up an interview 3-5 days from contacting me. The first store's HR person sent out a very curt email, explaining the job and instructing candidates to email her back if we were still interested. She told us we had 24 hours to reply and that she would be calling to set up interviews that evening (for the next day.) I emailed her back, explaining that I had to work that night, but would give her a call back during my break. She called, I couldn't answer. After calling back and leaving two messages--nothing.
The next HR person called me on Christmas Eve, hoping to set up an interview the following Monday. (I was given the impression that these interview windows weren't really negotiable, and you were out of luck if you had something planned before they called you.) He mentioned that there might be a skills test, and that he would send me all the tools I needed. That email came on Saturday afternoon, right as I was about to go to a wedding. The "tools" wouldn't open (why wouldn't you save the file in an older format to make sure all your candidates could access it?) I emailed him about it, but got no reply. I just decided to wing it (it was a poster design for an upcoming event). The whole thing put a bad taste in my mouth ("Hey, design this poster for us in less than 48 hours during one of the busiest weekends of the year.")
The actual interview was a panel of six people. Two were incredibly warm and welcoming--the rest looked like they hadn't had their coffee yet. I definitely botched the interview. Come prepared, walk the store before, and be familiar with their products and signage. They asked me to draw out a sign for a phrase they gave me ("Frozen at the peak of freshness") in 3 minutes, which actually made me less nervous. One of the questions they asked me was what sort of display I would suggest for their upcoming Italian wine expo. The rest were pretty standard.
They didn't call me back in the 24 hour they promised, and I was rejected for an in-house candidate. I was also later rejected for the assistant graphic artist position. To conclude, you have to have a flexible schedule when dealing with these people and ready to drop everything when they decide to have interviews. If you want to be in the graphic design field, I feel there are better ways. I won't be applying to any more Whole Foods positions--I'm tired of the run-around and to be perfectly honest I've had more professionalism from lesser jobs I've applied for. If you really want this job, I feel like the best way is to start elsewhere in the store first and work your way up.
