I work in a medium-sized company on a team that takes on special projects and kind of struggles to explain and define its role in the wider office.
The team has been without a manager for a year, the previous manager left for personal reasons.
I started working on this team about 2.5 years ago and it's my first job after uni. A slightly more senior colleague is leaving and they're hiring for his position. The role in question is called something like 'project coordinator' and would come with only marginally higher responsibilities than my current one.
The lack of management and problems with the team's wider mission have driven away some very talented and experienced people.
I have applied for the internal opening and decided I'll just change company if I don't get it. The people that I learned from the most over the past years have all left, so the pace of learning in my current role has slowed down a lot.
In truth I might leave in a year's time even if I get the promotion because the environment is quite difficult overall. But having this title would look great on my CV and give me the chance to acquire important communication skills etc.
Over the past years I have accumulated certain tech skills that are very important to the team, so if I did leave they would be in a very difficult position. However I'm worried the guy currently heading the team (and also conducting the interviews) doesn't realise this because he's way too high up in the company to actually spend time with us.
My question is how I can convey that I'll be actively pursuing external opportunities if I don't get this promotion without it sounding like a threat.
I should note that I have in fact already had a first interview and didn't really emphasise this, but there might be more interviews or another opportunity to talk to the interim manager. How do I approach this?
UPDATE: Not that it really helps to answer the question but I ended up getting the promotion. I avoided making any sort of threat or obvious comment to the interviewers
