Recently, we had a new department open up in our tech company and people from my department were being interviewed for possible selection in the new department.
It was rumoured that people who do badly in the interview would likely lose their jobs (our department will close down in a few months).
After I had my technical interview for this new department, people in the office asked me if I could tell them the interview questions. I did not want to give them an advantage and, also, I think it is not ethical to share technical interview questions in such a scenario.
But I noticed that a person who had an interviewed after me was discussing the questions that he was asked. He was telling all the people who were yet to be interviewed about the questions.
To my surprise, they were the same questions that I was asked.
So, I emailed the manager who interviewed me and told him that some people (I did not mention any names) are sharing their interview questions with others and that I think it's not ethical. I said that I wanted to share this with him. I haven't received a reply from him.
Did I handle it correctly? What should have I done?
update
Got a reply from manager after 8 hours. He thanked me for the information.
