Hello everyone,
This is my first post on mumsnet but I've been an ardent follower for many years now. Am ever so thankful for the bottomless source of info, tips, and banter. I've finally mustered up the courage to engage in the community, partly because I'm dreading CS interviews and am in dire need of help.
As per the subject, I've been starting to feel quite stupid trying to figure out the right balance of language, examples and self-promotion needed to nail behaviour-based interviews. I've been in CS for some years now, so one would think that I'd have figured it out by now... But a series of 2's received following a recent interview has thrown me off quite a bit. I found some useful pieces of advice on here before emphasising the importance of landing the how and why, and making the outcome really clear. But I'm also aware that a star-studded example or one in the relevant operational or policy area is more likely to pick recruiters' interests. Where's the dial here? 
I'm certain I must be doing something wrong, but my "mind's eyes" must be broken because I can't see what. I'd be super grateful for views from other CS/public sector employees or anyone familiar with this mind-boggling process!
