Logistics in Motion interview questions

They hired me no problem it was as if it was too good to be true. i went inside and it was if i was in a rat race. i did some people having fun with what they were doing but most of the people look very depressed. also the pay is one of the only reason im going to keep this job . i have been told many times that wont keep this job for more than 3 months and most of the friends who did work their quit after a month
