That's not what was said. At all.

To be perfectly honest, I doubt there are dozens of director-level interview samples because there aren't tons of engineering directors, further "director of engineering" is a management, not technical role, so wouldn't be given questions like this, at all, and of the remainder, most of them were promoted from within google, not hired from outside it.

Most new hires get screened in some manner, but very few new hires are directors of engineering, so I'd mighty curious to see your source for the interview questions they got.

What these questions are are the standard set of pre-screening questions asked of a potential SRE IC or maybe TLM candidate. A SWE wouldn't be asked these questions, because they aren't related to the role. A SWE candidate still might get screened, but not with these questions.

A question on Glassdoor (for a Director position) is in the same vein: "How do you tell if a calculator is 8 bit or 16 bit."[1]

> How do you tell if a calculator is 8 bit or 16 bit.

As someone who has reverse-engineered calculators, that question has me curious. You could implement the same external behavior regardless of what processor a calculator uses. So I can't see any way to determine the bit width. Is there an answer I'm missing? (Also the question ignores the many 4-bit calculators.)

(Of course you could open up the chip and take a look with a microscope, which I've done. But I don't think that's the answer they are looking for.)


Can an 8 bit calculator display/operate on numbers bigger than 2^8?


Yes, by operating on multiple bytes


In the same way you can have bigints in a 64bit system...


a) 2013, when they still asked brainteasers

b) That's a different question from this set about UNIX arcana, so it's not the same set

c) All of the other questions on that page are non-technical, so this isn't a question from a standard director set either. (It may be what 'DannyBee said, that people assumed they were being screened for a much higher position than they were actually being screened for.)
