Zendesk interview questions

Was contacted by HR/Recruiter representative at Zendesk and had the standard phone screening interview review of my resume. Was instructed to review some online materials and demonstrations and try the free version of their solution. Got a call back from a hiring manager for a phone interview and an opportunity for me to demonstrate the free solution to him via web. A couple weeks later went in for the in person interview with the hiring manager and a few members of the team. Received positive feedback and was called back for a second in person interview, both at the San Francisco HQ. This whole process took about 4 weeks but communication from HR or the interviewer did keep me informed throughout the process. I received the standard HR decline email. Process was professional and polite just seemed the scope of the job changed after I started interview process.

Two days after submitting my application I got an email from the recruiting team confirming they received it and that it is in line to be reviewed. Two days following that communication (on Friday) I got an email from the recruiter who scheduled a phone interview for the following Tuesday. The interview was short - right at the beginning the recruiter (who was calling from the UK) stated that she had loads of other candidates to interview, and I came first because I tweeted a question to Zendesk. She asked me how long I have been in Dublin, and having my CV in front of her stated that I got no prior experience supporting a product, and that the job was highly technical - which, given my keen interest for technology and all the qualities a customer service rep must have, was not a good fit. Having familiarized myself with the Zendesk approach to hiring customer support staff known as "Don’t sweat for tech: make customer service skills your hiring priority" (you can find it on their bog), I was surprized to hear that. The recruiter did not ask me what I knew about Zendesk, or any other questions related to customer support. She said that she'll pass my CV to the hiring manager, and if approved, I'll get a demo task by Friday. But on Thursday the status of my application on Jobvite turned from "In Process" to "Not Selected". No communication on that status change followed.
