Neyber Client Success Manager interview questions

The first stage was a call with their Recruiter, the second stage was a face to face interview with their Markering Director and the third with the Founder. Unfortunately, I didn't hear anything back after the third stage, no feedback, nothing at all. Up until then, the process was going well but I don't think it's fair on a person to completely ignore them after they've come to your office and spent the time on the interviews.
