I have had so many issues in where I work mate and they couldn't be arsed supporting me in that do I am not sure how proactive they would be in helping me leave either sadly.
This jobs for the boys seems to be a lot more widespread than it seems. I know one day someone will take one look at me and just want to hand me the job there and then but it's finding that job. Not to sound arrogant but I genuinely am brilliant in work. Today alone I sold myself as someone who works alongside senior managers elsewhere, brought in more than one system (considering my level is a massive thing ) talked about qualifications that not even they would have and as someone who knew everything they were talking about. You can see why I'm a little down haha I shouldn't be in the job I'm in any more, I'm better than it. I don't say that as an arrogant thing, it's true. There is so much more I could be doing in my career yet I look around at where I am and see them all rotting away not planning on improving their situation and just feel that will be me in another 10 years
Might have spotted an issue here, you are coming across a bit arrogant and above the people you work with.
If this comes across that way in an interview, they would think twice about the team morale and how it would be affected.
Maybe, you are trying too hard to impress. Just relax and be calm.
