After the initial informal call with a recruiter, I was sent a task and asked to spend 3+ hours on creating a presentation that would then be reviewed by the hiring manager to decide if I was getting a first interview with them. I pointed out that this seemed exclusionary given the vague formulation of the task, while also asking a lot of candidates with little in return. The replies I received from the company were increasingly antagonistic and refusing to acknowledge my concerns or accommodate my request to go over the task during a call as the nature of the job is collaborative anyway. I declined to proceed because of this.
