Back in college.
We had this course in which we gathered in teams and worked the whole semester for another teacher building a product. We had roles, like QA, devs, PM...all the works.
I was PM and during our first presentation of the product to our teacher and the client we showed the work of our first month of work. At the end, our teacher asked our QA, who have been silent the whole project and hadn't answered my mails asking for tests, if he had found any problems. "Oh, yes. The whole site is broken. I can easily break throught it"
The faces of the rest of the group showed a level of surprise that made the teacher ask if he had informed us: "No..."
Our client, another SE teacher, started to laugh and that was that.
It was awful
