There's irony. Asking for GitHub is 10x worse than algorithmic questions. I just went through the interview process at big companies, with all the resources out there it's easy to get good at these types of questions.
During my professional time I write software to make money. During my free time I write software to make money. As an aging software engineer algorithmic questions just screen for how much time you're willing to put into an interviewing. GitHub screens for how much of a sucker you are.
Yeah, could be. Though if you provide a hiring company with a GitHub profile demonstrating your dominance, and then you are expected to waste another 6 hours on trivial algorithmic questions you probably did 100 times in the past 10 years, you'd probably just pass on that "opportunity". Those algorithmic questions were anyway originally meant to find the "best of the best", now they are used for entry-level positions. It's like asking an accomplished lawyer about what happened in 1758 and what was the effect on common law.
