I applied online. I interviewed at Petco (San Diego, CA) in Mar 2015
Interview
Standard recruiter screening followed by phone and in person interviews. No standardized questions. Seem to have already made up their mind before bringing me in. No surprises...fairly standard. No additional prep was needed.
Quick decision, swift run through the interviewer stack. Situation they were describing as the current state worried me against joining. Seemed like they were and had been in constant flux.
