Experiences with hiring... | Reply
We get a few stories posted back here of what it's like to apply at Microsoft or Google or something. I thought perhaps I'd describe what it's like being on the other side of the table at a smaller business.

We just got through hiring a couple programmers for junior level development positions. While the resumes came in a little slower than in previous hiring runs (it's a strong job market here), we got a good mix of people and a lot of resumes that looked strong. We got people with CS degrees, people with diplomas from technical schools, people with a fair bit of experience, new grads, referrals from current employees.

A big hint for this stage: make sure you know what the job is; then when you're asked what you want to do you can say things related to the job you're applying for. When you say you want to be doing "sales and management or something" in 5 years, it's hard to take you on as a junior developer. Being honest is great, but when you come to an interview for a coding position it's sort of catastrophic to say you don't like coding. It's hard to overstate how important this is.

Honestly, if you came into an interview with us fresh out of high school with no experience but said "I like programming and I want to be a programmer and here is some things I programmed" you probably would have made it to the final group (and if you could program, you'd be hired).

Speaking of which: develop something that can be shown to someone. We typically ask people for sample code or something - and mostly we get back garbage. Rudimentary school projects. Web sites that are long dead (and now just a parked page at GoDaddy or something). Vague "I helped with this part of this website" things. Applications that can't be run (or comprehended) without a certain database set up. Your code sample doesn't have to be spectacular; it just needs to be something that compiles and runs and does something and actually has some code that can be looked at by a human (and preferably one without a thousand frameworks installed). Not all job interviews are going to ask for something like this - but for ones that do you have a real leg up if you have something demonstrable (even if it's a game or trivial utility - by the time you get this far it'll be a technical person looking at you, and we like games).

Last hint: know how to program (and this part is probably wasted here). For our final cut, we had people do a coding exercise. Now you may be thinking - ooh, this is the part I'm interested in. Well... you'll probably be disappointed by the following story.

Here's what I had people do: Given an array of 1000 integers (values from 0 to 99), return the one that is the most common. In the case of a tie, return the smallest tied number. Before the exercise started, I demonstrated this on paper and made sure people understood the problem by giving them some samples and making sure they picked out the right one. I had people sit at a computer and code up the solution (in VB.net/VS 2005) while I watched and helped.

Some people didn't know VB syntax at all. This was kind of disappointing, given that the position was clearly a VB.net position, and we made sure during the interviews that people were familiar with VB (or at least claimed to be). And the people knew they were coming it to do a coding exercise. Anyways, this wasn't a big issue - when I saw people struggling to declare an array, I just told them how to do it. I wasn't really trying to test people's VB knowledge; a new syntax is easy to pick up if you're a competent programmer. I'm just saying that if you are applying for a Java job, you should get some basics of Java sorted out. Makes a better impression.

I was much more concerned with the problems people had coming up with an appropriate algorithm. I'm not talking about an efficient algorithm or the best algorithm or a bug-free one or something - I'm talking about anything. We had allotted an hour for the exercise, and by the end of the hour many applicants (including some with CS degrees(!!) or years of experience) hadn't made a real stab at the problem - and this is with some verbose help from me. At about the 20 minute mark I would talk to them about the general plan of going through the numbers and counting how many of each number they encounter. If they were stuck again by the 45 minute mark, I'd go over the plan of looping through the array of counts and remembering the largest count that had been encountered. Very few people got to the point where we were worrying about resolving ties. Lots of people went out on tangents trying to use SQL or sorting or something. While I guess some of that could have worked, it didn't help anyone who tried it.

In the end, the coding exercise was decisive. We had a couple people who walked through it fairly easily and we hired them.

Anyways, I come out of this with some reservations about the educational system and a renewed respect for TopCoder competitors. Some people may think I'm exaggerating something in the above - but I suspect those involved at hiring for smaller companies will hear the ring of truth.

Anyways, hopefully you found something in that useful, encouraging, or at least entertaining.

EDITS: minor, for clarity.

Thanks for the stories!
This forum (General employment) is very instuctive overall, but posts like yours definitely bring something valuable to the community.

Don't you have a CS degree yourself? If you have you must have gotten it at a better university than the one I got my (maths) degree. Otherwise you would have known you barely need any skills to acquire a CS degree. Let's just say I know you were not exaggerating.

Interesting. I've always thought the same about CS degrees here, but I was pretty sure that this was a flaw of the french universities..
What about other countries ? Does `CS degree' mean anything there ?

I haven't seen any 'CS' degrees in Brisbane, but the Information Technology degree with CS major at my university is the same.

Wow - then I guess I'm really lucky to study in Warsaw.

It's the same in the UK where they are seen as vocational courses that churn out candidates with basic Java/C++/SQL skills who have had very little exposure to problem solving.

How is it in Warsaw? Is it hard to get a CS degree? As hard as a math one?
Re: Experiences with hiring... (response to post by jmzero) | Reply
It's clear you're exaggerating a lot.
We all know that many people manage to pass their exams knowing next to nothing, but it's blatantly obvious that anyone with a degree in CS will solve that task fairly easily, even those who struggle to pass the courses and finish several years later than expected. I wonder what kind of people were going to that interview if there is any truth to it.

It's my experience that people with CS degrees are a mixed batch of skills, but people with math degrees that do programming are generally good at it.

Actually, I doubt he's exaggerating at all.

I'm glad you doubt me. From the other responses, I was starting to think maybe I had just set the bar too high or something and that I was wrong to be disappointed.

To be clear, I am in full agreement with you - I have no idea how you can get through a CS degree and not be able to solve that problem while holding your breath. And, to be clear, the bulk of the applicants were technical school grads, but there were some with CS degrees.

I guess the reason I wasn't more surprised is that this isn't our first attempt at this kind of thing. We'd previously done "on your own time" challenges with mazes and such - and got back either horrible, lengthy, non-solutions that barely passed the example (or just "that's too hard" or "I don't have time for that"). So while I made this challenge as easy as I could, in the back of my mind I kind of expected it to give people problems. I just didn't expect it to give an hour's worth of problems to so many people.

EDIT: here's the previous challenge we asked people to do a few years ago (before I was much involved in TopCoder - so I apologize for the ambiguous problem): here. The guy who turned in the only strong solution on this one is my office neighbour now.

In 12 years of technical recruiting, I can say without reservation that what jmzero is describing happens every single day, not just in small companies but across every industry, company size and geographic location. I've given out very, very simple logic problems as well (problems that I can solve, and I'm completely useless when it comes to math or programming) and have gotten back at best 25% correct answers from CS graduates or even from those with Masters level degrees in CS. Here's an example: "given a 3 minute hourglass and a 5 minute hourglass, how could you accurately measure 7 minutes?" It would amaze you how many people with a CS degree from a good university can't solve that problem given 10 minutes. Some couldn't solve it given all the time in the world.

Oh but you should be disappointed about it! At least I am. I was just saying I was getting used to it. And of course you shouldn't lower the bar if you don't want to destroy your company by hiring incompetent people.
Re: Experiences with hiring... (response to post by harvey6ft) | Reply
I actually don't think that is a very good question for measuring "smarts" or ability. I think it falls into the "aha" category of questions. If you see the trick it is easy, if you don't, it's not.

I think jmzero's question is good because he makes sure people know how to solve the problem first. Therefore he is testing if they have the ability to convert a "human" algorithm into computer code.
