I don't know why people are downvoting you. I can tell you that I've seen the same thing and having dealt with the fallout of bad hiring, I'd rather miss some good or even great candidates rather than hire someone bad. Edi: To clarify: I work at Google.

You always run the risk of hiring someone bad. Interviewing, particularly rigorous interviewing, is a game that doesn't map very well onto work itself. That's why the true test of a hiring process is the firing process. If you can get rid of people that can't hack it, rather than letting them gather as detritus in your system, you'll be far better off than if you simply pretend that you can actually avoid mistakes.

I couldn't agree with you more.

I think the gmail answer would have sunk her too. Google is an advertising company -- 1/4 (25%) clickthrough on Gmail ads (not even search) is just crazy. People click search ads because they're looking for something, Gmail ads probably get an order of magnitude less click through (people aren't in gmail to find new things). For someone applying to an advertising company, she needs to know their basic business model…

>If she thought about her own usage, she'd realize that it was an insanely high number... It's dangerous to generalize from yourself like that.

Better to generalize from one data point than to generalize from none.

Hiring two people so you can fire one is a lot more expensive than interviewing 10 to start.

But what are the relative probabilities that each method will result in exactly one good employee?

I worked for Google for a few years, and did a lot of phone screens. Most of the people who I interviewed probably felt the same way as this lady. The process may seem brutal, but it is impossible to invite everyone in for an on-site interview, and the phone screen does a pretty good job of filtering out the definite nos (although I'm sure that some good candidates are rejected). I could count the number of people wh…

Out of curiosity (I have no plans to apply to Google), what kind of criteria are used to identify prospective candidates? For example, does Google only look at the top 10% of academic performers and winnow from there, or sample across the board and then start filtering for critical thinking? I'm just thinking about the fact that many industry luminaries didn't bother to finish college, but rather stayed long enough t…

How many industries luminaries would be good contributors at Google? Wozniak, who prided himself on building circuits with fewer chips than anyone thought possible?

Would he be happy programming in Java?

With regards to your last point: I don't doubt that the vast majority of hiring processes aren't correlated with on-the-job success, but Google is definitely the kind of company that would strive for objective measures and to refine their process. They at least claim it's working. I think it was on the Stack Overflow podcast that I heard a discussion of Peter Norvig's remarks about this in Coders at Work. He evidentl…

It would be very interesting to know how Google measures on-the-job performance since you obviously can't talk about correlation without numbers backing it up. I seem to recall having read that on-the-job-performance is not as easily measurable than Norvig seems to imply but I guess that if they successfully managed to reach this Holy Grail they probably won't share the numbers, even less the methods.

Promotion at Google is based on peer feedback, so I'd guess that's what they use.

This wasn't an interview, it was a test. I had a similar experience with a startup. I was interviewing for a Marketing Communications Manager position. Essentially PR. One of the unofficial interviewers (at 24 year old MIT engineer working as an email marketer) challenged me with the question "How many barbers are in San Francisco?" We proceeded to map it out the analytical process on the whiteboard. He wanted to see…

I don't think this is such a terrible thing, although clearly this adversarial approach to testing ideas isn't for you, or everyone. Enrico Fermi used to challenge grad students with similar questions, the famous example being 'how many piano tuners in Chicago?'. I don't think it's a stupid or impossible question, but one that seeks to establish how you go about estimating tricky things and thus identifying fruitful…

Your logic is flawed (as is nearly every "solution" to one of these problems I've seen). The question wasn't "How many barbers should there be?" It was "How many barbers are there?" This is an important distinction as your approach shows the appropriate number of barber shops that can reasonably be operated and have no shortage of customers due to hair growth speeds. I would approach the problem from the opposite direction. How many distinct professions are there in San Francisco? What is the current population? What are the percentage breakdowns of those professions? At that point, you can easily get the number of people employed as barbers. Now, did they want individual barbers, or the number of barber shops? You then only need to infer the number of barbers per shop, rather than estimating a lot of data that isn't readily available.

My Google interviewer had a toothache. I didn't get an offer. Their recruiters are notoriously independent; not sure that's a good thing. I was actively sought out, but had no chance because the interviewer had a bad day. Question: is it more important to keep out the bad ones but lose some good ones, or vice versa? (ie, what's the correct balance between false positives and false negatives?)

I've heard from several Googlers that false positives are orders of magnitude worse than false negatives. In reality, I think it's more clear-cut - there are those developers who know all about tries, algorithms, parsers, GC strategies, unit testing, OS level details, networking, etc., and those developers who know how to program in Blub for Blub libraries. For most positions, Google wants the former.

I am mystified that companies use interviews in hiring despite the overwhelming academic evidence that interviewing does not work,

I conjecture that what we are discussing is primate social behavior (yes, "monkeys in a tree") and social hierarchy in action. Of course we _are_ primates, so maybe it _is_ vital that Google hire enough "alpha males" or whatever.

The interview process in this case worked fine. But it's silly and probably causes them to miss a LOT of good candidates. It's measuring a subjects ability to think critically... quickly and while under a lot of pressure. Is SPEED of critical thinking important? How many positions at Google require people to think on their feet? How many positions require them to be comfortable/effective talking to strangers on the p…

Speed of critical thinking for simple questions like the $0.10 ad-click question probably is important. If someone can't figure out the answer to that one pretty fast, they're probably not going to successfully figure out really hard problems at all.

Apart from the arithmetic fail, I think she did more than well in the creative/copy part. In fact, I think she did more than well. She recognized the brand value, put the story edit in line with the brand/tagline and made a plausible copy on the spot in a situation that is far from normal for that kind of work. All in all, it depends for what she was interviewed for, but then again Google is not good at/famous for copywriting/advertising - they are a technical analysis company, not a creative one.

What surprises me is the reasoning path she took (ie estimating customer behavior). I'd have tried to guess how many servers they need for that (uuuuh...100,000?) and how much they cost a year ($1000 each, $100m?) and what's an acceptable profit margin (20%? So about $300,000/day in earnings). Then again you could figure Google makes about $5 billion a year in profit, say a tenth of that comes from gmail, and the pro…

The internet claims 4 mill http://erictric.com/us/how-much-money-does-google-make-per-d...

And the internet can't do math...

"In the second quarter alone, Google has managed to reel almost $1.5 billion in earnings."

"If you do the mathematics here, Google is making upwards of $4 million daily"

Except they mistakenly used the quarterly earnings in place of annual earnings. So it would be in the range of 4x that.
