Need help devising interview questions for a junior
-
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.

Second - the silly question
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.

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? :)

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?

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?

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. -
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.

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

The easiest way for me to have an "idea" of the knowledge of the candidate was to develop a written test with general concepts of the thecnology and a few logic and OO questions. Then just read the test, see how he performs and then talk to him about general stuff, way he works/worked in the past, prospective about the future, etc.

First, what not to do. Normally the interviewers' objective is to find out how much the interviewee knows and what experience they've had. Asking trick questions and posing zany challenges will not help you find this out - they are just traps that bad interviewers fall into. Also if you go in (or send the interviewer in) with a set of questions about .net it turns from an interview into an exam. You could do that by email. Waste of interviewing time so that is something else to avoid. Instead, just ask them what you want to know. A good technique is to start by asking them what they've done (I'm asuming that someone else is dealing with questions designed to put them at ease and to check their applications - those a pretty essential ways of starting the interview). So your questions can start by asking the junior just how much .net experience they have had. Stop. Let them speak, and listen. If they say some interesting stuff then pick up on it. The purpose of your questioning now has to be to find out how much of what they are claiming they did themselves: if part of a team what was their role? What did they contribute specifically? e.g. answer: we designed a piece of software that did wonderful things. follow-up question: yes but which part of it did you personally work on, what was your exact contribution (to be asked every time they say "we did" instead of "I did"). Then shut up and listen. Then probe specifics, to see whether they can support their claims by demonstrating a genuine understanding of the task they are describing. What else have they done? - same pattern: find out how much was their work and how much they understood. Repeat until you feel you have got a measure of the candidate's abilities. They might be nervous to the extent that they dry up, in which case it is OK to lead them gently, using their application as a way in. But stop at regular intervals and listen. Try to get them doing 95% of the talking. Above all, if you are the interviewer resist the temptation to pontificate or otherwise show off. This isn't the time or place for that. HTH

Aw why :( That's not even part of .NET.. Is that even a basic thing? (I would be unable to answer those two questions)

Definatly Chopsticks for foods which are indigenous to Asia.. else spoons. :laugh:

How do you make sure something works? Make sure it does what it says it will do. A bug will keep the software from doing what it is said to do. I will say that you have been out of the engineering business far too long if you actually think that your 1) is possible. Bug-free code does not exist except in small examples where no user interaction is needed and only very basic logic is used. Even then, you could find a mistake or vulnerability somewhere.
