Consider making tutorials for publications that you're interested in, but are nontrivial to read through and understand. Building a tutorial will give yourself a deeper understanding of a problem, help you communicate that understanding, and benefit the larger community.

Thank you. Do you think this will be appreciated for a job interview? I think it will take lots of time and effort for that to happen.

Yes. Part of the job interview will be selling your knowledge through past work. Spending the time to tutorialize content will make it easy and stress free to talk about it to a general audience. Being able to communicate your point clearly is fairly essential IMO.

As per if they'll look at it themselves, I'm much more skeptical. The same issue is present (checking at the resume stage or at the first filter stage) with other portfolio pieces though.
