Explaining your reasons for moving on after several months
I accepted a job offer several months ago for a few good reasons-- I needed to get away from a toxic workplace and a bad boss and also, I had pretty much accomplished all I could at my last job and there was no further chance to grow.
So, I took a transfer and started a position in a new dept. I did not receive a raise but have gotten good training. Well, a place I've been interested in for a few years invited me for an interview. It looks very promising and the salary will be a lot higher.
I know they'll ask me during the interview why I'd like to leave this new job after being there for such a short time. The honest answer? There's really no room for growth. It's public sector so the only chance to move up would be applying for a higher-level job and competing with internal and external candidates. There are no true promotion opportunities. The salary the new place would offer would take me years to reach at my current org. I could very well be stuck at my current pay for the next five years with tiny COL raises.
Would it be ok to say I want to leave because the growth opportunities are very limited? And avoid mentioning the obvious salary issue? (Everyone knows my current org underpays people).
In addition, I also prefer the sector I could move into if I'm hired at the new place. I'm just more interested in the subject matter. Again, it comes down to growth. I don't foresee myself happily taking courses at my current org to develop expertise in an area I don't see myself working in long term.
