I applied online and was contacted by a recruiter within a few days of my application. The phone screen with the recruiter was basic. The recruiter asked routine questions which I easily answered. I was contacted the next day by email saying they did not wish to move me on to the next round of interviews because I was not "empathetic enough" toward customers. Wow! I was taken about because I've been in my career for over 15 years. If I wasn't empathetic, I would not be successful as a CSM. I felt the real reason was ageism because I gave several examples during the interview which tipped off the recruiter that I was likely over 35. Greenhouse is a young tech company and I'm certain they want to keep a certain demographic of employees in most departments in the company, especially client-facing roles. So be forewarned, if you are over 35, Greenhouse will probably not be the best fit unless you are seeking a role that is recruited by "older" recruiters or more experienced HR personnel. Unfortunately, ageism is very common during the interview process.
