First interview with the recruiter who I found very professional, and who left me wanting to know more. Second interview with the line manager, which was more of a constructive exchange than an interview. This led to another telephone interview with a strategic account executive (field). Again, a really good conversation with some good (if a little challenging) questions. Then I had a face to face interview with my N+1 and N+2, and finally a live demo of the product. Overall, the interview process left a great impression on me, and a strong conviction that I would love working for Zendesk. I loved the fact that despite being challenging, I fell that I was treated as an equal, and despite my lack of background in software sales, they seemed to buy into me as a person. Top marks for that !
