Quick questions like this always throw me. I don't think about programming in a way where free floating questions make much sense to me initially.
A a b b c c c c d e
Give me a function that given a number returns the letters that have that many in it. You have 60 minutes. Any language.
letters = %w(A a b b c c c c d e)
letter_map = Hash.new(0)
letters.each do |letter|
letter_map[letter] += 1
end
def print_count(map)
map.each do |key, value|
puts "\"#{key}\": #{value}"
end
end
def match_count(map, count)
map.select { |key, value| value == count }.keys
end
print_count(letter_map)
match_count(letter_map, 4)https://www.penny-arcade.com/comic/2008/02/13/professor-layt...
Why are you always asking me to rediscover and reimplement the Fibonacci sequence when none of us give a fuck about it? This whole thing's insane, what have I become.
This is after the initial resume screen and sometimes even after they did an online leetcode style test.
Some took one look at it and walked out. Others would solve it in under a minute. Everyone in between.
There are lots and lots of big company jobs where you can skate by writing ~100 lines of code a week (or less!) all inside the mandated Big Company In-House Framework. In fact your boss demands that you work this way.
I mean, that was totally me for years, so I’m not judging too harshly.
I’ll still google “how 2 for loop” sometimes.
How would anyone know? Once a candidate fails the screen, the company rejects and never gives a second thought to the candidate again.
Does any company do follow-up to see what happened in the future to rejected candidates? I've never heard of that happening.
The coding screens are just assumed to be infallible, so the candidate must have been a fraud. It's unthinkable that the screening tests themselves are wrong, because then the whole hiring process is misguided.
After a while it got to the point where I’d walk in give an easy five minute coding exercise walk out and give a thumbs up or down. They could use any language editor or tool they wanted. We even provided a few alternatives they could pick from in case they just had a weird mental block on our preferred one.
Others would make sure that they weren’t too insane personality wise.
Other team members were constantly shocked by candidates that were verbally great but couldn’t do deal with hashes or arrays at all.
