A huge number of software engineers work for companies that don’t allow them to have side projects, so they don’t/can’t have code anywhere in public. Similarly for developers where software development is their job, they may simply not feel like continuing to work in their non-work time (or they may have a family they would like to spend time with, etc). But similarly take home tests aren’t going to give you anything interviews aren’t going to show - if you’re concerned about people lying about their competence you should assume that they’re able to pay someone to do the work for them anyway. After all the threat model for a take home test is dishonesty. I really think a lot of people think the goal of an interview is just to determine “can this person do the mechanical part of writing code” which is the easy bit.
