Amazon Software Developer - Internship interview questions

I applied online, I was emailed with a link to an online (non-coding) assessment, that was very logic and pattern matching based. After I completed that I received another email with a coding challenge and "personality test". I must have done well because around a week later I received an email with an offer. This experience was ultimately what lead me to choose another offer. I had no contact with a human until the offer. The coding challenge wasn't very hard and the personality quiz was horrible, I don't know how they gain any information about anyone through it. I didn't want to take an internship, where I hope to be mentored, at a company who doesn't even take the time to use humans to recruit. For all they knew I could've been a robot.
