Interviewing internally for a step up role similar to my current job-help!

[Statsquestion1]

I’ve applied for an internal role at my company and would appreciate some advice if I get an interview. I literally only applied yesterday afternoon.
It’s basically the exact same job I’m already doing but in a different department, and it’s the next level up (around 10k more). From the job description pretty much all of the responsibilities overlap with what I currently do. Which is great in theory yes…but…
My question is how best to handle this in the interview. Obviously my current experience is very relevant, but I don’t want all my answers to come across as “well I already do this job”. At the same time I don’t want to undersell my experience.
It’s not a leadership role, just a more senior level of the same job, so I’m wondering how best to show I’m ready for that step up without sounding presumptuous.

If you’ve interviewed internally for a similar step-up role, how did you approach it?Thank you.

Probably they're looking for evidence that you can handle being stretched that extra little bit - more responsibility, more creativity, more taking charge in a crisis - whatever the role demands.

Look back at your time in your current role and see if you can find an example of when you went above and beyond the job parameters. If there was a problem, and you solved it, remind them of that time (because they will have forgotten all about it I expect) and walk them through what you did.

Some of the interview questions may be hypotheticals ("what would you do if XYZ happened?"), so think about disaster scenarios and how you might handle them.

And maybe tell them something about how you're ready for a challenge? You can hint at feeling a bit stuck in your current role, if you think they might not want to lose you to competitors.

I will definitely have examples prepared. We use the star method for some of our interview questions too. Thank you @Melarus

It’s probably worth exploring ahead of time if there’s anything you’ve underestimated given it is graded higher

Yeah I’ve literally gone through the job description over and over, there’s only one
aspect that I don’t do but I could do so it’s not a big deal imo. I’m pretty sure it’s just a higher grade due to the dept. (Without being too outing in a way)

First identify why it’s more senior.
for example it may be the same role and responsibilities, but it’s got a broader geographic base or it has more complex technical questions or it deals with bigger customers.
then be prepared of how and why you think ur ready for the more senior role. It is possible that the job description does not identify the difference so you need to discretely find out about the job.

The job is the exact same yes…however the dept is of a different function as such (but I would know the basics of the dept). It’s not too outing I suppose so I’ll say it. I work in the quality side, this dept is production so more technical, however it’s not something I would have NO knowledge of as I would have an understanding in order to perform aspects of my role, iyswim.

In that case, you could tell them you find the production side of the industry quite interesting ... fascinating even (!) ... and if there were times when you had to deal with the production team or process while you were in your current role, remind them of that, and try to use it to show how you'd be a good fit in that team.

thanks yes I’m thinking this is the best approach to take. 🙌
