I interviewed at Zendesk
I completed the first interview stage: the first with HR (30 minutes), It went pretty well, in fact the Guy told me I was a really good fit to the role and then told me he was going to send the next steps for me to select the days for the next interview. Unfortunately, I never received anything more or any response, despite sending twofollow-up emails..
So it let me wanderging why this guy lied to me. He let me asking for something that wont happen.

Interview
I completed three interview stages: the first with HR (30 minutes), the second with the Team Leader (30 minutes), and the third with the Head of Department (1 hour).
As part of the final stage, I was asked to complete a case study. This involved selecting a client, sharing the initial email I would use to approach them, and preparing a presentation on how I would generate leads and close the deal before transitioning the account to the Account Manager.
Unfortunately, I never received any feedback or response, despite sending more than five follow-up emails... within 3 weeks.
Second round involved a role play with 2 senior SDR people from Zendesk where you had to qualify them in or out. After the role play they offered feedback on the role play.
