I have always struggled with my confidence. Don't know why, but it has always been an issue for me.
Academically, I have a strong CV. (Oxbridge degree, well recognised master's qualification and other professional qualifications too). I'm also fluent in a second language and can get by in a couple of others.
On paper, my career history is pretty good too. Good range of experience, including a series of senior management roles, successful projects, substantial overseas expertise etc. I've always had good appraisals and most of the people I've managed have told me that I'm a great manager. I've generally achieved or exceeded targets, got great feedback from clients and external partners, brought projects in on time/on budget etc. However, I've never been very good at networking or self promotion, due to my crippling lack of confidence. I don't like pushing myself forward or blowing my own trumpet, but I know that I need to do this better in order to succeed at a senior level. I'm much better at singing the praises of my team.
I was made redundant last year, which has added to my confidence issues. I'm now job hunting and I have found a role which looks ideal for me on paper - it's a really interesting and exciting role. My experience and skill sets are all relevant, and I meet the criteria in the person spec. The salary is in roughly the same ballpark as what I was earning previously. (Starting point slightly below my old salary, top of scale a few thousand more than what I used to earn). However, as soon as I start thinking about the application, the little voice in my head starts to spiral out of control...there's no way I will get this job, my experience isn't enough; other people will be better qualified; you'll get scared and screw it up at the interview etc etc.
I have always been like this, but it's getting worse. I fucked up a couple of interviews last year that I should have aced, and I'm scared of doing it again. I feel like I'm going to sabotage my chances of getting another job that I really want, and I just don't know how to silence those inner naysayers.
Can anyone offer any words of wisdom, especially if you have managed to overcome similar insecurities? All tips gratefully received.
