Infinite Chicago Management Trainee interview questions

The company is very shady. I was told that this is management trainee position at first. First interview is very easy, only 10 min brief communication with a manager there. Second interview is shadowing a sales there to do door-door sales. By then , I realized that I was cheated and basically wasting a whole day to do free work for them. If you don't want to do door-door sales, don't bother to apply.
