Google admits brainteasers were useless for hiring (2013)
Here are two thoughts on tech interviews. One controversial and one (hopefully) not.1. It's good that companies like Google are able to reassess their hiring policies and learn what works and what doesn't. It's easy to criticize companies for doing things that don't make sense or that we know to be bad, but often these things looked like good ideas at the outset and you need some amount of trying new things (many of which won't work out and may have negative consequences) in order to improve things.2. The way hiring works in tech isn't really that bad. It doesn't really measure what matters for job performance but tech pays well and so many people want to do it that you need barriers to entry. The real losers of the hiring process are the companies that waste lots of money on inefficient hiring practices. If you compare the effort required to get a high paying tech job (really just doing practice problems for a few weeks/months) to any other high paying, professional field we have it much better.
