What is the marginal cost of a gigabyte in gmail?12 Answers
I had no idea what marginal cost is but after a lot of hints, I finally came up with 1$ / a gigabyte though that's probably on the low end. The right answer is probably a bit higher, say 2-3 $ / a gigabyte (from the costs of servers, disk space, maintenance, set up of servers, maintaining webpage, designing user interface and then offset by the advertisements and click-throughs)
probably even less than that now. http://thenextweb.com/2009/11/11/data-quarter-price-googles-plan-chrome-os-storage/
Isn't marginal cost the cost to produce an additional unit? So costs like designing the user interface, maintaining the webpage (which would have to be done no matter the gigabyte capacity) shouldn't be accounted for.
Ah, you clearly would have made a better candidate than I have. Like I said, I didn't know what marginal cost was so I just came up with a ballpark figure.
Here's my guess at what they're looking for. Marginal cost - this is the additional cost for adding a user. It doesn't need to take in to account the software development effort, but it should take out the atomized cost for everything else. You need to price out the the cost of the enterprise HD/GB. We can call it $1 by GB. Then you need to realize that there needs to be redundancy, so at the lest we need to double that number, if they put a super high value on data retention triple it. Then you need to think about server cost and divide that out, server rack space cost and physical rack area...etc. So if it's $1 for the actual HD space it's probably more like $2.50-$3.50 for the total marginal cost. I don't work for google, but my guess is that they're looking at the though process. What will change with a marginal user increase and what will not. If you only think of the cost of the HD then you're not getting a job with google.
The simplest answer is to look up the Amazon S3 costs (currently platoing at 5.5c/GB) and assume that the economics are fairly similar.
To correct my own post - these are per/month prices. So the eternal retention prices would be ~50 times higher, which gives us the same figure as Jon's.
Considering the money they make per account signed up with gmail, I'd say they definitely make money per gigabyte spent for gmail, but I'm not sure how much.
I never worry about the capacity of my gmail account, it seems to me the cost of an extra gig of gmail storage is zero. As it is the mission of Google to make sure every users always have enough storage capacity and Google is doing a great job in this area, so the maginal cost of a gigabyte in gmail should be zero.
If it was a cost, Google would not exist. When analyzing costs, and especially marginal cost, one must consider all aspects. Once one considers the return too, the cost goes into a negative
The marginal cost of adding a gigabyte is either zero or thousands of dollars.. Either the gigabyte is already physically in existence or you would have to build a new server. The marginal cost is not averaged across all gigabytes. There might be a minor increase in energy consumption due to this extra gigabyte, but who will notice that? If your goal is to stand out in an interview, I would suggest going the Thousands of Dollars answer. For those non computer guys out there, let's relate this question to something physical.. What is the marginal cost of adding one more person to an airline flight.. Their are two situations, the plane in not already full so we can essentially neglect the cost of the additional passenger since it is so low.. (The extra energy to move the 200 pounds, when the plane is already moving hundreds of thousands of pounds, and the 25 cents for a soda..) But if the plane is already full, then the marginal cost of one extra passenger is the cost to fly a second plane.. Thousands of dollars...
Marginal cost is the cost of adding one additional unit, so fixed costs of Gmail are already taken care of. So the cost is the cost of the hard drive + any labor to install and configure that hard drive for gmail. Take a sum of the costs and then divide it by the size of the hard drive (GB) and you should have your rate. I think it will be well below a dollar. In my quick math I had it at 20 cents but that assumes consumer pricing.
Let's say you have 10 bags of nails, and each nail weights 10g. You also have a scale upon which you can weigh a combination of the bags or nails from the bags once. You know that one of the bags is off by a certain amount of grams, but you don't know which bag or by how much. How do you find out, with one weighing, which bag it is?10 Answers
Number the bags 1 through 10. Take 1 nail from bag 1, 2 nails from bag 2, and so on. Take those 55 nails, which should weight 550g, and place them on the scale. If the weight differs from 550g by a certain amount, then that tells you which bag it is and how much it's off by.
If each "nail weights 10g" as posed in the problem the ONLY weight you will get is 550g. My Idea is the instructions state "can weigh a combination of the bags or nails from the bags once." Place bag on scale result should = 100g, add bag 2 = 200g ect. when you add a bag and the result = less than the 100g, result = bag number and weight and difference. As you have continually adding weight is counts 1 time.
Who cares? If you run out of nails go get some more.
You guys are doing this wrong. This is a twist on a very old problem, that actually has to do with twelve balls and can use the scale only three times. The trick is to divide the bags into smaller groups of 3, and see in which direction the bags move. It's easier if you draw it out. It is from "games for the super intelligent" by James Fixx.
If I can only weight them once... then I'd put all the bags on, one weigh in and take the bags off one by one. The weight should go down by 10g each time until you get to the bag which is off. Technically it's one weigh in at the beginning and the rest are clearing the scale.
Take all the nails out of the bags weigh them divide by 10. The number wont come out even, bag up your nine even piles, then the last bag you have is the one that is "short".
This is a stupid question to use in an interview. Presumably by the time people get to this level, they've already taken the SAT and GRE, the latter of which includes a logic section. Test people on things that are going to matter for the company's bottom line, not a logic problem.
I agree with kgar 79. The problem states that you can weigh the nails individually, which means you can take them out of the bag. Once you do, you'll be able to see which bag has more or less nails than the others. Since the nails all weigh the same, any variation in weight, will be determined by whole nails.
Simple, and it can be done without weighing anything. Count the number of nails in a bag and multiply the number by 10g.
kgar79 got it right. Just dump out all the nails, put the same number of nails in nine of the bags,their weight is now 10g x the number of nails per bag, then put the rest of the nails in bag #10. Then weigh it and now you know which and by how much it is off. You don't actually even need the scale.

I got asked this question on Tuesday by some newbie who had only been at Expedia for two months. I then googled it. This question is listed as one of the "Top 10 dumbest interview questions" out there. Go figure...I gave the dumb chick this look that said: "are you for real? I have an MBA and a graduate degree and you are asking me this $hit???"
I would be a platypus because I can adapt to anything, I can build, swim and can warm in the winter because I have fur.
At a party everyone shakes hands, 66 hand shakes occur, how many people are at the party?9 Answers
it's not 12, it's 11
sum of the series 66= n/2( 2*1 + (n-1)*1) n=12
You can suppose there are n people in the room and think of them in a row. The first one has to shake hands with (n-1) people (because he doesn't have to shake hands with himself). The second one has already shaken hands with the first one, so he has (n-2) shakes remaining... and so on. So you have to sum: (n-1)+(n-2)+(n-3)+...+1= (n/2)*(n-1) Then you have to solve (n/2)*(n-1)=66 and you get n=12.
n(n-1)/2=66 so n=12
You can think of this problem as a combination problem: (N choose 2) = 66, and then solve for N. That is, N! / (2! (N-2)! ) = 66. Simplifying this equation leads to N(N-1)/2 = 66, and the integer solution to this problem is N = 12.
66=x!/((x-2)!*2) which gives 12
Can you meet the hiring manager in 3 hours?6 Answers
Wow, they really sound very disorganized & disrespectful. I reckon you would have hated working for them, doesn't sound like they could be good with their clients!
Yes, I found the leadership at BI to be quite unorganized, there always seems to be firedrills with unhappy clients, count your blessings you didn't take a job with them.
This is a great information to have about this company. Thanks for posting this.
The senior leadership at BI have a track record of publically humiliating employees on our morning calls it's comes with the territory of a CEO company owner who throws his weight around. You just have to ignore it as best you can.
I think the issue is that director positions are a dime a dozen here and people don't last long, I am on my 3rd office partner in as many years & Steve is likely going to leave! Management therefore really doesn't invest too much time or effort in the candidate evaluation & hiring process.
Typical Courtney stirring the pot, reckon she's had more office partners that projects.

What is the base salary offered?
Did you start the job already? what are the schedules like? I know it can be any shift but if you have any details please let me know. How is the training? Is there any other testing besides the one for the license? Thanks
Yes I've started already, just completed my 4th week of training. My training schedule is 9am to 5:30pm mon-fri..then my regular work shift will be 9:30-6 mon-fri... The only test that really matters is the licensing exam, although there are several other exams throughout training that they'd like for you to pass but it's not as mandatory as passing the licensing exam..
How long does it take to get and answer back for the background check and drug test?
Was the licensing exam difficult? Do they use Kaplan?

What was the technical interview about? Do they ask you questions about programming? I have the MANH interview soon and am not sure how to prepare for the technical interview! Thanks!
@ Homer Simpson, The technical interview was simply them asking me to explain a "technical" process on the whiteboard. There was no programming, though I used a programming example in answering this question. The overall interview process requires little preparation, with the exception of the panel interview since I'm assuming you got the question before hand. Again they want to see the following: 1) Logical thought flow 2) Ability to present/explain on a white-board 3) Can assimulate concepts (including programming) quickly
Thanks Boss for the quick reply! I just came back and I think it went well. How much time did they take to reply back to you?

Hey, what happened in your interview ? How many interviews took place and what questions were they focusing on?
Hi, can you tell me if you had a F2F interview with Vitech. I have it next week. Can you tell what kind of questions they ask.
All were the basic questions you would expect, because they read from the papers left on the table by the store manager. One they kept asking was about my seasonal job, that I wasn't going back to, due to the commute and not driving any more, which I explained at least 5 times about and they still couldn't understand that I wanted to work near where I live. What part of that was confusing, maybe they just didn't understand because they didn't have it written down in front of them to read from.6 Answers
try 2 explain your problem by many ways maybe they can understand what in your mind or what u want
It was explained several times in many ways, but you can tell when someone isn't going to hire you and they keep coming back to a point that was explained FIVE
It was explained FIVE times, in several ways. What part of "I would like to work closer to home, because I only live a few blocks away and can't drive a 140 mile commute daily anymore" and I am not driving anymore? The first time it was explained in a clear and concise manner and when asked "Where do you see yourself a year from now?" and the response was "Working here". Isn't that clear enough?
Hey Secret, do you talk like you text? Because you sure write like you are texting someone when you wrote your comment. Your comment is hard to understand or maybe you think like the people giving the interview here, Confused.
I think none of them are confused in the text above. justrusaya are confused when reading the text above .

This pen looks ordinary but writes amazingly. I have so many of these cause the gel is so smooth. It makes it easier to write in cursive and the color is very bold. I really like this pen.
