Applied for ASMT, and took a math skills test. I must have passed that, as my DM called to set up an interview. I dressed for the occasion and drove to the store I would be interviewing with. I had 2 interviewers who took turns asking me questions. I had prepared by writing down a few example stories (experienced I had accumulated through various jobs, volunteering). It is a behavioral interview so be prepared to have a different kinda of stories. (Customer relations, coworker stories, etc) they asked me 9 questions and all in all, it took about 40 minutes.
I received a call two days later saying I got the job. Starting next week.
They used the SBO outline. (Situation, behavior, outcome) you must explain what happened in detail, the action you took, and the outcome it had. They ask you to use as much detail as possible as they grade you by points on how much you have covered the SBO guidelines.
