It's ok to suck at interviews. Learn from it.
I have been interviewed 6 (7?) times by Google. The last time I was getting on a bit in IT terms, at 39. When I first got to the office I could see many young nerds. I asked the interviewer how they felt about wrinklies like me - she said it'd be fine... Didn't get the job. I can guarantee it was nothing to do with age - I actually really did suck badly at the interview... And that was the 2nd set of interviews.
Now I pity all of those poor buggers I have interviewed in the past - it is soul destroying. You are never relaxed and can't show the real you, you panic, you fudge stuff and if you're like me you'll do anything to get the hell out of there. A simple negative comment is 100,00 times as powerful as a positive one.
Anyhow, here's the response I got from not passing the "phone interview" the first time:
Thanks Brad,
That's ok - I was lame in the interview.
To become "unlame" again - and to help others I did a bunch of
research and posted this post:

Please forward to Tom (the guy that did the phone interview), he might
recognise a few of the questions :). After all, we can't have people
at G! thinking that I am lame! Perish the thought.
Ta,
Riley

Interview/test anxiety
I get interview/test anxiety. So I've listed all of the stupid reasons I've failed in interviews so the techies can laugh at me :) I almost always knew the answers quite well, but I just blank out and panic sometimes. Also, my interview to offer ratio is quite high (I reckon around 3:1). So don't worry kiddies if you get your ego smashed because you screwed up something fundamental. It happens to others also.

A: <WRONG ANSWER>!!! <-- haha, Goose.
Note: a physicist once complained in front of me about the standards being so low that I could do a unit in his department. This was after another similar mistake. He was right, standards were low that year. haha.

We need a new techie recruitment process
We need a new techie recruitment process. I've been guilty of being a whiteboard interviewer. :( The focus should be on whether a dev can build an actual product. Not whether they can solve a problem, in front of new people, on a whiteboard.
The problem with software technical interviews: If you get an easy, fundamental question wrong, then your entire career is judged on that. E.g. That guy didn't even know X, well, that tells you everything about him. It's happened to me many times, and I've done it to others many times... Now I work in recruitment. Now I've got a chance to fix this. If we can crack this one then the rewards are large.
Despite years in the industry, degrees, etc. I still stuff up basic questions in interviews. Today it was a basic threading question. Last time was basic power laws. Both questions, i would answer properly if casually discussing. But I just freeze up in there and say the first thing that comes to mind. Is this a problem for everyone? It doesn't matter if I know or not I DON'T know under test conditions.

Tech: Predicting the Future
Dumb father has moron son...
1968: Dad gives up programming coz he "doesn't think there's a future in it".
1998: In a job interview with Ericsson I tell them I don't think there's much future in having the internet on phones.
Genetics :( *** sigh ***

The stages of tech job transition
The stages of tech job transition (aka getting fired + looking for a new job):
1) sweet - I get to sleep in.*
2) I should start my own business, yes - now is the time, before it's too late! Madness ensues for 2 days,
3) Check job market - nah, not yet, sleep in*
4) Start running out of cash - apply for some jobs with lackluster resume + no cover letter
5) No replies. Go hard on the CV and Cover Letter.
6) Get replies! Yay - interviews!
7-11) Fail 5 tech interviews because the questions are arbitrary, you panic, you forget everything, and the interviewer is as smug as a game show host.
12) You finally get a job based on you randomly getting tech questions correct.
13) You work 80 hours a week on someone's dream, buying into the hype for a few years. Have a breakdown... leave or get sacked, and start all over again :D
* A lot of techies are night owls

The Ultimate IT People Test
Below is a list of 800+ names of influential IT, Com Sci, and computer related people. There are Linux gods, Microsoft gurus, famous scientists, notorious hackers, game designers, authors, entrepreneurs, and more. How many do you know? Go ahead and test yourself.
For each name:
1. If you recognize the name give yourself 1 point.
2. Give yourself another point if you know an approximate date of birth.
3. Finally, a further 3 points for identifying what that person is famous for.
Underneath the list is a set of links to help you find the answers. You'll have to do a little bit of research, but you wouldn't be doing a geeky test like this unless you enjoy that kind of thing... would you? :) * Update - I've removed some duplicates and marked those numbers with DUPLICATE REMOVED.

For each name:
1. If you recognize the name give yourself 1 point.
2. Give yourself another point if you know an approximate date of birth.
3. Finally, a further 3 points for identifying what that person is famous for.
Underneath the list is a set of links to help you find the answers. You'll have to do a little bit of research, but you wouldn't be doing a geeky test like this unless you enjoy that kind of thing... would you? :) * Update - I've removed some duplicates and marked those numbers with DUPLICATE REMOVED.

C# Interview Questions
The ability to do something does not imply that you can explain it conceptually, or even that you understand the concept of what you are doing. So I have prepared a list of questions\tasks that I think would be useful to complete before going for a C# related job. I have also provided a separate page with questions AND answers for the first set of 173 questions, and another page for the answers to the rest of the questions (not including Scott's questions). You can find the first link below the first set of questions and the second link at the bottom of the post - they are also directly below if you want to jump straight to them.
http://www.toqc.com/entropy/TheAnswers1.html
http://www.toqc.com/entropy/TheAnswers2.html
Before you do the questions, make sure you follow these rules:
Rule 1 - Don't say to yourself "yeah I know that" and move on to the next question. Answer the question as if you were in an interview.
Rule 2 - For the questions that require code - write the code yourself on a piece of paper, don't use an IDE.
The Questions\Tasks:
- Name 10 C# keywords.
- What is public accessibility?
- What is protected accessibility?
- What is internal accessibility?
- What is protected internal accessibility?
- What is private accessibility?
- What is the default accessibility for a class?

- What is the default accessibility for members of a struct?
- Can the members of an interface be private?
- Methods must declare a return type, what is the keyword used when nothing is returned from the method?
- Class methods to should be marked with what keyword?
- Write some code using interfaces, virtual methods, and an abstract class.

- Write code to show how a method can accept a varying number of parameters.
- What is an overloaded method?
- What is recursion?
- What is a constructor?
- If I have a constructor with a parameter, do I need to explicitly create a default constructor?
- What is a destructor?
- Can you use access modifiers with destructors?
- What is a delegate?
- Write some code to use a delegate.
- What is a delegate useful for?
- What is an event?
- Are events synchronous of asynchronous?
- Events use a publisher/subscriber model. What is that?
- Can a subscriber subscribe to more than one publisher?
- What is a value type and a reference type?
- Name 5 built in types.
- string is an alias for what?
- Is string Unicode, ASCII, or something else?
- Strings are immutable, what does this mean?
- Name a few string properties.
- What is boxing and unboxing?
- Write some code to box and unbox a value type.
- What is a heap and a stack?
- What is a pointer?
- What does new do in terms of objects?
- How do you dereference an object?
- In terms of references, how do == and != (not overridden) work?
- What is a struct?
- Describe 5 numeric value types ranges.
- What is the default value for a bool?
- Write code for an enumeration.
- Write code for a case statement.
- Is a struct stored on the heap or stack?

On the subject of emergence.
Emergent properties (http://en.wikipedia.org/wiki/Emergence) of collections of smaller "things" seem to be very real physical properties. By saying a property is emergent we are saying that its parts cannot fully explain that property. It seems that, as though "by magic" these emergent properties appear when systems get complex, and large enough. The trouble is, even though they are real there is no overall classification system for them (like that of fundamental particles). So why not make one?
Let's have a crack at it. first off we need a model and some rules.
Emergent properties (http://en.wikipedia.org/wiki/Emergence) of collections of smaller "things" seem to be very real physical properties. By saying a property is emergent we are saying that its parts cannot fully explain that property. It seems that, as though "by magic" these emergent properties appear when systems get complex, and large enough. The trouble is, even though they are real there is no overall classification system for them (like that of fundamental particles). So why not make one?
Let's have a crack at it. first off we need a model and some rules.
- Our model will be a universe made of a several instances of a single indivisible, fundamental particle, which we'll call A.
- The concept of "size" in our universe will be governed by the amount of A particles we have. E.g. a size of 3 (AAA) is bigger than a size of 2 (AA). Emergent properties will happen at different sizes.
- As with our (real) universe we don't really know what an emergent property is. There may be many more than we can percieve. So we'll assume that emergent properties happen with collections of A. Our rule of collections will be simple, if we have a collection, n of A then the number of emergent properties of a certain size x is the number of times we can fit x into n (rounded down). NOTE - this rule is arbitrary.
- Finally, we'll take it one step further and give each emergent property a name. Better still, we'll call it a new particle (e.g we'll say AA = B). Remember though, we only define these new particles by the number of A they contain, not by each other.
Confused? Me too, here's an example:
First off, pure reductionism (no emergent properties). Let's count the number of particles in this system (we'll try it with a universe containing 5 A) .
1 AAAAA
2 AAAAA
3 AAAAA
4 AAAAA
5 AAAAA
Size does NOT matter in this universe, if you used a microscope to peer down through the scales you would see at size 1 the 5 instances of A. As we get larger (2 and up) the 5 particles still totally describe the universe and nothing new happens (is emergent). No molecules with new properties, no vortexes, no human consciousness, etc. - just cold, hard, boring particles. The number of things in this universe is 5.
Now let's add in some rules of emergence.
1 AAAAA
2 (AA)(AA)A
3 (AAA)AA
4 (AAAA)A
5 (AAAAA)
At size 2 for example, size does matter - we have 2 new B particles (AA) and (AA). Following this logic further you can see we have an (AAA) particle, which could be called C. Then (AAAA) = D and (AAAAA) = E. When we replace sets of A with other letters we get:
1 AAAAA
2 BBA
3 CAA
4 DA
5 E
The list of all things here is (A,A,A,A,A,B,B,C,D,E) which is 10 entities. The number of things can be counted by using a basic formula:
# of things = sum[i=1,...,n] (floor(n/i))
So we can loosely say that 2A = 3 things (an A, another A, and a B) so, roughly speaking, 1+1=3.
So what's this good for?
The classification and categorisation of emergent properties is adhoc. What if there is a pattern in the REAL WORLD by which we can classify and possibly even predict emergent properties?
Something to think about...
