Need help devising interview questions for a junior
-
First of all, you haven't been tasked with. You've been asked. Tasked with is vapid management bull serving to make something sound much more dynamic and go-to than it really is. Second - the silly question; ask how many piano tuners there are in London - this should help you to see how they respond to odd requests, pressure situations and what their thought processes are like. Do they start by assuming that the population of London is x, and out of that population, y% have pianos and it takes z tuners to service that many pianos? Do they tell you that they'd Google it? (Ironically, Chrome's spellchecker doesn't recognise Google; it offers Goggle, Googly, Goodly and the rather fun Go ogle as choices). Third - test them on the basics (here I'm assuming the position is for a .NET developer with some experience). Do they know what an interface is? Do they know what an abstract class is? When would you use one over the other? Do they know how to get data out of the database using something other than a DataSet/DataTable?
I have CDO, it's OCD with the letters in the right order; just as they ruddy well should be
Forgive your enemies - it messes with their heads

Need help from people with experience of interviewing, rather than being interview. I have been tasked with creating some .net question for the interview for a junior and I have no idea where to start and would love to have some sensible and as well as wacky (because I know here I'll get some!) from people that have had such experience
As barmey as a sack of badgers Dude, if I knew what I was doing in life, I'd be rich, retired, dating a supermodel and laughing at the rest of you from the sidelines.
Think of a small program, that you could write in say, four hours. Give them VS2008 / 10 / whatever you use, four hours and a spec. See how they get on. Other ideas: We've previously interviewed for a C++ / Windows position, and asked questions like: C / C++ specific, testing basic knowledge of bit operators and pointers. 1. Write code do determine how many bits are "on" in a byte. 2. Write code to reverse a string in place in a buffer. 3. Write the standard
atoifunction from scratch Windows Specific 1. When do you put elipsis on a menu or button? 2. Why would you use threads in an application? (we look for three different scenarios) General software engineering What's the point of testing software? (you'd be amazed how many people say "to make sure it works") -

I've found that even the fairly rubbish candidates recognise them now and have pretty much prepared stock answers. I stopped asking this type of question when I realised that it wasn't helping make a decision. Pretty much everyone could answer it. It doesn't show you have logical thought processes, it just shows you've read a few "how to interview" blog posts.

We ask two types of technical questions: First - Simple problems on paper. Something dead easy like sort this list, reverse this string or count the bits in a byte. We give them a pencil and paper and get them to write it in front of us. Syntax/spelling/language isn't to important. Principles and approach is. If they choose a real language, the method signature should be present and more or less correct. We also do a 'spot the bugs' style question and database or class design if its relevant to the position. All on paper/whiteboard. Second - A real programming task. We give them a laptop with the appropriate IDE/compilers set up. The problem should take around 1-2 hours. Try to give them a bit less time than it should actually take so you can see how capable they are at prioritising and describing the remaining tasks. past questions from Google code jam[^] is a good source of problems. The early rounds are pretty easy, the later rounds are much harder. Don't make it too hard. You then get them to present the code to you.

Just ask "Spoons or Chopsticks?". Watch their faces, it befuddles them. Then ask a technical question, see if their brains can swiftly recover, it is a good technique for whittling out the permanently bewildered.

The point is; make your own up. You don't have to go for an obvious one.

The style is easy to spot though, and if you know the style, you can pretty much make up an answer to any of them.

For forks sake, is that best forking response you got? :)

OK, I'll bite! That *is* the point, isn't it? I can think of expanding the idea, like "to make sure it works against specification X", "to make sure it works consistently", " to make sure it works even in the face of adversity", but they're all expansions on the first point. Iain c++, q2 - My first thought was swapping end and start char / wchars, then work to the middle, but what about utf8? Or do I win a cookie for thinking about that?
I am one of "those foreigners coming over here and stealing our jobs". Yay me!

No. The point is to prove it doesn't work (ie find a defect) For any piece of software, one of these three must be true: 1) The software contains no defects. 2) The software contains at least one defect, and I know what it is. 3) The software contains at least one defect, and I do not know what it is. The role of the testing process is to determine which one is true. If 1) is true, you are finished. Release the product. If 2) is true, you fix the defect, and reevaluate. If 3) is true, you continue testing until either 1) or 2) is true. So, the point of testing is to move from 3) to either 1) or 2), and that involves finding defects. Of course, at some point, you have to take the view that "absence of proof is proof of absence", in that you can't find any more defects, so you assume there are none (ie you assume 1) is true, when it may not be). When and how you make that decision is what puts the 'engineering' into 'software engineering', and one of the things that makes the question a jumping off point for a broader discussion.

Indeed. One of the points of the question is to see if the candidate things in terms of
char*only, or can think about other aspects of a (deliberately) vague spec. For example, I didn't even say if the buffer was null-terminated or not. -

Keep a straight face and ask him to write an intractable problem in pseudo code. Time him.

Try and cover the basics, so things like: "Give an example of when you might use a static field on a class" "What's the difference between an interface and an abstract class" "Describe the purpose of the 'ref' keyword in a methods signature" Ask them about database interaction: "How would you execute a SELECT statement against a database" "Which method would you use to retrieve the value from the first column of the first row" Perhaps something on using things like app.config files? Also maybe a couple of questions to demonstrate that they know the difference between passing by value/reference. It's outside of .net but maybe something about version control as well? Hope that helps
