I went through two rounds of interview.
The first round was an online video call conversation where I was interviewed by a Senior Marketing personnel and a Senior Content Writer. I was asked about my experience in content writing, the tools/software I used for the same (extensively), questions about content/copy (landing pages, running online ads, etc.), my biggest achievement in the profession, and which book I was presently reading. The video call lasted 45 mins. The questions were quite technical, eg., how would you use google analytics to verify what kind of engagement your pages/posts are receiving?
The second round was a performance based test, again on video call but with me sharing my screen as I worked. I had around an hour to write one ~500 word blog post, create one instagram post, and write one cold email to a new customer pitching a product/service. I was allowed to use any tools of my choice.
The interview process for this company is overall technical and thorough.
