I've been working for the same company for few years now and I've been promoted few times, my salary was also increased, so I don't have any complaints from financial/role perspective, as I think stuff are developing with a good temp.
However, on each feedback I receive, and every performance review I have, I always receive ONLY positive feedback and no constructive criticism, no improvement points, no areas for improvement - nothing. On each review I asked more than once for any recommendations, constructive thoughts, etc. and people always say they can't think of anything (I've switched managers and teams, so it's not even the same people on my reviews). I do agree with the positive comments about my performance and recognise my strengths. I've always had above-average performance in my previous jobs too. But I don't believe it's realistic to be said that there's nothing in a person's work that can be further improved - technical skills, soft skills, time management, list is endless. I have a list of 50 criteria to be assessed on in my review and I don't believe there's a person alive who can be "exceptional" in 10 of those, and "good performance, without comments/suggestions" on all of the remaining 40 of them. I know that this might seem like non-issue and like I'm just a crazy person to many people reading this, but this is important for me. I want to continuously improve myself and keep growing personally and professionally. Without being given a hint in which areas I should focus my attention, it's really hard to do so.
As I mentioned - I've raised the question more than once, and when the answer is always "nothing", I'm afraid keep pushing is just crossing the line with being too pushy. I've also raised the question in other occasions where feedback was discussed, and have tried to pop the question in informal conversations with my managers too since I've been working here.
My questions here are: is there any point of keep pushing to receive any constructive feedback, and how should I do this given that I already tried, but failed? Or should I just drop it and avoid potentially getting myself into trouble because of this? Also, if for a second we do accept there's nothing in the "con" side from their perspective, shouldn't this actually be an indication that I'm just not challenged in my current work and should consider switching to different role/company so I can keep developing my skills further?
