This is outing so am trying to be vague
My colleague Henry applied for a management role within our civil service department. I applied for a software role in another government department. Both of us got job interviews which will be structured using the civil service framework (star method)
I had a meeting with my manager on Tuesday to prepare. Manager ran over some mock questions, but I didn't answer them. This exchange was about 30 seconds out of an hour meeting so it was in one ear and out the other as they're not relevant to the technical role I applied for.
Henry asked me how my meeting with my manager went and I told him I can't remember what the mock questions were. He told me to tell him if I remember as they'd be more relevant to the job he applied for as he's applying for my manager's position.
On Friday, I had a meeting with a career mentor who sent me over some example interview questions. I didn't speak to Henry at work this day (either face to face or digitally) as we were both busy
Today, Henry had his interview and I asked how it went. He mentioned one of the questions he was asked. I was able to remember this question as one my career mentor sent to me on Friday. Henry started shaking and turning red and asked me why I "didn't tell him the questions and it would have REALLY helped him prepare over the weekend." I apologised, it didn't cross my mind as we didn't see each other. He kept repeating that he's disappointed as the questions would have REALLY helped him.
Now he's avoiding me. I think he thinks I've sabotaged his chances with this job. Aibu not to tell him the questions? It genuinely slipped my mind, and half the office had the same interview he had as it's a direct promotion. I'm sure someone would get in trouble for giving an unfair advantage
