I mean WTF were you being asked to do, glue-code, or make a library, or architect a big project?

Tell me if I'm wrong, but, isn't python easy to pick up?

even if python is easy to pick up I'd bet my rear end the interviewer would ask about the tricky parts (like say putting lists in default arguments) to check if the person *really* have python experience.

I mean if they were general programming questions he'd be fine with any language or pseudo-code even.

talked to some fintech guys on the phone today. they were looking for people interested in functional programming and it actually seemed like a pretty cool place to be to actually get better at programming, but ugh, fintech. they did send a small homework test though, said it'd take about 1 to 1.5 hours but no time limit, most common languages allowed. they also said it was more about clarity and simplicity than about performance, but to feel free to use functional patters where it was appropriate. three small tasks, two of them trivial, third was to implement a very small and trivial RPN expression evaluator. I did in in python and the idiomatic way is to just have a simple for loop and use a list as a stack, but since they said to use functional programming I ended up doing it with reduce instead and it was much uglier. well, idk. guess I'll see if they get back and maybe talk to them some more.

yeah python is a tough one for demonstrating functional style. I'd have used haskell or sml for that because it's a kind of cliche problem to solve in a language like that to demonstrate pattern matching and recursion

for anything trickier than that I'd go back to python lol

I don't know either of those though :negative:

They're explicitly not looking for people with actual professional experience in functional languages though, an interest and some familiarity with the concepts is enough, or so they claim

I kinda see the point of this question: it's to check if you're familiar with the way python implements classes. __new__ creates the new instance (thus some people are pedantic about calling it the actual constructor) and __init__ is called afterward to customize (or should I say initialize?) it. they got bad names imo

however it's a mostly irrelevant internal detail unless lol if you take doing OOP in python that seriously.

questions about magic methods are largely bullshit but this one gotcha about lists in default arguments I actually think serves as a good question for checking if the person has any python experience. because it gets everyone at some point.

the worst trivia interviewer i ever had was this fat slob at a mobile PBX company who wanted to hear e.g. Java's limit on the number of methods in a class

I told him "whatever it is, if you get anywhere near it you're doing something terrible" and he just went on to another trivia q

You see the thing is he's a terrible enough programmer to be intimately familiar with that kind of thing, so he pretty much sprung his own trap there.

yeah if you do

code:

def let_the_dogs_out(poop, toilet=[]):
    toilet.append(poop)

toilet will grow in size every time you call it without specifying a toilet and the poops will just keep building up

what you need to do is:

code:

def let_the_dogs_out(poop, toilet=None):
    if toilet is None:
        toilet = []
    toilet.append(poop)

in summary,

it's not in the first call, it's assigned in the function definition statement :eng101:

code:

>>> def f(x=[]):
...    x.append('butt')
...    return x
...
>>> f.__defaults__
([],)
>>> f()
['butt']
>>> f()
['butt', 'butt']
>>> f()
['butt', 'butt', 'butt']
>>> f.__defaults__
(['butt', 'butt', 'butt'],)

tangential to this, one thing that very few people seem to know about is that user defined functions are open objects

code:

>>> f.butt_holder = 'lol'
>>> f.butt_holder
'lol'

so you can assign variables inside functions this way, it's kinda neat in my p-langer opinion.

I like coding challenges because I'm a huge sucker for brainteasers tbqh

I feel like 2/3 problems and 30 min for each is pretty fair game.

but I don't have much of a choice given my situation so I just accept whatever

I've had a couple now with 90-minute coding challenges (done independently, without having to explain your thinking as you go) and that's a pretty good length imo. you get enough time to do a somewhat interesting problem, and if you spend 15 minutes planning/60 minutes coding/15 minutes cleanup and finalizing your solution you have plenty of time to breathe without dumping way too much time into it

i haven't had a >2 hour one yet, making time for that would be pretty rough.

the only coding challenge I liked that had someone watching was one where the interviewer just had me share my screen and I could use my own IntelliJ setup. the others are varying levels of okay, but really fuckin stressful because you're in a weird environment
