First you have a chat with one of the managers, Webstep is a pretty lean company. They show you how Webstep works, their salary structure, clients and such.
You then get a change to introduce yourself, talk about what you do, what you want etc.
Webstep only hires senior consultants, i.e. 5 years of experience or more , during the meeting your CV is gone through, talk about particular clients but nothing special.
After that, you get a call if they feel you are a good fit or not.
