I've been exceedingly lucky landing gigs at great companies that don't filter with these questions. I worked for LeadGenius (YC S11!) and the technical portion of the interview was super fun and effective; I was asked to write a useful piece of software in python which I later applied to school projects! No whiteboarding, no data structures. I'm currently interning at General Motors and their interview was similarly sans whiteboarding, and I'm surrounded by brilliant interns and coworkers. Hmm. At least for me and a few of my peers, being asked to solve the type of problems presented in the article raises some red flags about a company's culture.
