Improper casing? what chu talking about!!
.Net is Pascal case except for parameters
Ah you're right. Sorry I've never written .NET professionally so I didn't know they used Pascal case.

If your language allows for overloading, you should use it

I'm with Cad on this one. Sure, the second option looks nicer in your intellisense but writing method names like the first option is not enough for me to not hire. I would be more interested in the actual implementation where they actually re-use GetItemPrice(Item item) in the other two methods with no copy/pasta.

"Improper Casing". Comments like that make me roll my eyes. Who gives a shit if it's Pascal, Camel, whatever. You can read English right? Like you won't know if it's a method or a variable unless you case it a certain way. Give me a break.
And when you're using an IDE overloaded methods are better than creating separate methods for each different type of call, even if the underlying code is the same. You can just type in the name and cycle through each overloaded method and see all the various ways you can call/use it rather than trying to hunt down different names for similar method calls.

A better test would be to say "we use X coding style here, can you rewrite this to confirm with my outlandish requirement?"

I'm a big follower, maybe to a fault of appeal to authority, when it comes to programming. If Microsoft, does something, and Sun does the same, and you don't want to use that, well, i really don't want to deal with your work.

I browsed through a few of the links but... I'm with the guy that commented, "These questions suck and some of the solutions are lies."

Agreed for C, and some of them are really elementary.
No interviewer is going to ask me what the structure of a for loop is

One of the Java questions is about the difference between Vector and ArrayList. Vectors were effectively replaced in Java 1.5 and their use is not recommended as a result. I didn't even know about them until I ran into its use in the code I inherited as it was never taught in any of my Java courses.

That's what one of the things I love about Python, your containers are basic:
dictionary(hash map in other languages, usually)
set
tuple
list
No queues, vectors, dequeues, arrays, arraylists, 100 variations of hashes and/or maps, etc. Pick your container and make sure your algorithm isn't shit, which is likely where more performance is lost than making sure you have the exactly correct container.

Maybe he is asking why you need to return a pointer from a function instead of being able to return the array? I assume C has that limitation since C++ has it at least.
You're mostly just complaining about Java having a ton of implementations of their basic Collection interfaces... Like mostly you'll just define your List as an ArrayList but sometimes you need something different. Granted Queues and Dequeues are different interfaces but they ascend to the same Queue interface. But it is nice knowing that you have a HashMap but sometimes you do actually need a sorted Map and Java already gives you a TreeMap for that occurrence. Just because Java gives you a ton of implementations doesn't make it bad it just gives you generic stuff (ArrayList, HashMap, LinkedList) but it can also give you more specific and granular implementations if required by your spec.
Vectors are thread-safe where ArrayLists are not thread-safe. Usually you don't want to pay that cost so you will use an ArrayList 999/1000 but sometimes Vectors fit their niche. Though since Java added the java.util.concurrent package in (I think?) 5 it is pretty much wholly deprecated.

It's not there in the official documentation from Oracle but Google has a note to just use CopyOnWriteArrayList class instead of Vectors in the Android docs.
It's one of the reasons I know the previous dev was a Java developer first and foremost. They keep telling me she was an Android developer but the code I'm working with doesn't back it up. There's zero adherence to the activity lifecycle.

Yeah thats the ArrayList inside the concurrent package which gives you thread safe Collections. Like I said Vector is pretty much completely deprecated since those collections came out. But Java being Java supports so much backwards compatibility I doubt Vector is going anywhere.
