Very relaxed and informal, they check your personal life to help you make a good balance in order to let you really do your job. Suits and formal dressing is not required. What they really check in depth is who you are and what you are good at. They want up-to-date experts.
And even if they are not looking for you, do contact them and send your CV, they also know the local industry and who's looking for someone, so they can help your mobility too if you are not hired with them.
