I went through the initial 30min phone screener interview with a recruiter. Although the recruiter was enthusiastic and fun to speak with, he talked roughly 90% of the time; therefore having no way of assessing whether I met requirements to proceed to the next round of interviews or not. In retrospect, it felt like he was going through the motions of a screener call, and he just had to get through the 30min. It's always great to experience various interviewing process methods, and understand the exceptional candidate pool, so I don't take it personal. That being said, it felt as if I was just a number to hit a quota or they already had enough qualified individuals to fulfill next round of interviews. At the very least, I'd say my recommendation to Zillow is a reply email saying the company decided to go forward with other candidates in the process. Never hearing back, even after my post-interview thank you email, just looks bad.
