Sam's Club interview questions

Applied online, I am still going through hiring process. I did two interviews on the same day all questions came from a script. Was sent to take a drug test and about 3 days later I was called to give the new references since the ones I listed never answered. About 3 or 4 days later I was called in for 3rd interview which wound up being 2 interviews as they brought in another manager for me to speak to. The first manager came back in and informed me that they still had other interviews and that they had to narrow the applicants down and that they would give me a call back either way. I thought the interviews had all gone good I have no idea why it is taking so long.

Very simple interview call you set up a day to come in interview takes maybe 20 mins you get interviewed by 2 people and then they call you back when you get the job
