Superfast IT interview questions

First round of interview requested a 3-5 minute video to introduce self and answer preset questions, then a 500 word blog post, and a social media post to promote that blog. I don't mind tasks such as these in the final round of the interview process, however this felt like too big of an ask before ever having a live conversation with anyone regarding the role and whether it was a right fit for me, and so I withdrew my application. Other companies have used similar tactics to steal free content from marketing professionals, and while I'm sure this task was set in good faith, I wouldn't want to investing time and effort without some reciprocation from the employer.
