I contacted them via their webpage, as per the job description, and was contacted by their recruiter via email to set up a time for a technical phone screen.

Upon conversing with the other SDET, I was clear about my background and experience and what I was looking for. However, his description of the role seemed to counter my view and my understanding of the online job description.

As we worked through the coding exercise, I hadn't had a lot of familiarity with the Queue class in .Net and was asking questions to try to implement it correctly, as there was no intellisense in the online tool we were using. His tone towards my questions grew more condescending as the interview went on. I kept my temper down, but it is not encouraging to try to answer a question when someone asks about your experience in a demeaning way.

I went over my experience again and where I may not know something, and he stated that the recruiter would be in contact. I received the rejection email within 2 minutes of hanging up.

It's fine to not be qualified for a job, but you can at least be nice to the person you're talking with. Maybe it was a bad day, but that was rude.

Implement a Stack using the Queue class with the given methods: Enqueue, Dequeue, and Count.
