We make this transparent. During the first round of interviews, you meet a recruiter, a senior colleague, and your future boss. This is a time to find out if your expectations and ours are the same. If the answer is “yes”, we invite you for a company breakfast where you meet the team you will join, see your office, take a look at your project and, of course, ask any questions you want answered.
