Thanks fro advice.
Had a teams interview last week for a job which seemed to go ok. Have a second interview later in the week, with a task to do first. The first was very definitely 'competency based' in style with classic 'give us en example of when you did...'. I did a bit of reading up about tit in advance adn identified some examples I could use fo various scenarios and the STAR technique; as It's been a while since I was in the job market - for a large corporation with procedures at any rate.
The HR woman said this will be 'competency based' too - so I'm wondering what further prep I can do - will it be yet more similar questions?
Contrastingly I've just had an interview at a very different company toady with a third generation business owner which was so informal and laid back it couldn't be more different. I don't think he'd heard of 'competence based' interviews!
