i failed quicksort the first time I interviewed at google. then got hired and worked there for 12 years and never wrote a sort.

I also complained that google's coding solution (docs, basically) was a terrible way to code, other companies use coderpad or whatever, but I expect that Google will never change this. They love to hire people who are excellent at coding CS approximate solutions, but have little to no judgement on how to do good software engineering.
