Walgreens interview questions

I went into an office, the managers were not there. That was a good start. They put a newbie for my interview, he had no idea what he was doing and the computer said that I passed the drug test. I never even took it! They also said that I got the job as soon as I applied to the job. Is that even legal?

My experience was kind of awkward they told me I got the job right after I signed up for the job an employee interviewed me had no idea what was going on because the manager and the second manager wasn't there and all they just asked me was where did I work and that was it and as soon as I was done with the interview I looked on the computer and I never even took the drug test and it said I passed.
