Oh yeah, for sure! I appreciated coding challenges while job-hunting because I did a lot of extra-curricular work in college that distracted me from portfolio-building. Code challenges let me show skills I'd developed without putting code on Github.
I just prefer challenges as a second step in an interview process, rather than a gateway to any human interaction.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
