I often see internal vacancies advertised at work which appeal to me, but when I look at the detailed role requirements, they seem to need skills and experience I just don't have. I don't then put in an application because it seems pointless.
However, on three occasions over the last year, colleagues in the same role as me and with (as far as I know) a similar background, have applied for jobs I've believed I'm not at all skilled for and been successful.
I find it difficult to think of a way to ask for the secret of their success without it sounding disparaging or like sour grapes - but I don't know whether they're genuinely better skilled than I am, or just much better at presenting themselves.
For context, I've recently seen an internal role I really like the sound of - at a higher grade - but as usual, I'm not convinced I could confidently give examples of all the required skills.
Should I apply anyway, or instead try to find opportunities to gain experience of those skills in my current role in the hope that another similar job will come up later?
I wondered what others' experience of this type of situation was - is it usual to dismiss the idea of applying for jobs unless you can claim to hold all or most of the skillsets?
Is there a way I could ask for advice from someone who has been successful without risking offence?
Any advice or opinions would be gratefully received.
