Great questions! But, the time to join Google was 5 years ago, not today.
You think you'll get rich with an option strike price above $500/share? Sorry. NEXT.

"How would you deal with an angry or frustrated advertisers on the phone?"
That one's easy: you don't. I remember reading that it's impossible to speak to a real person at Google's AdWords department.

These interview questions are largely urban myth. I never heard 90% of these asked, and brain teasers have been banned for like 5 years at the company.
October 11, 2012 at 2:04 pm, Joe said:
I definitely got some questions like these when I screened for an engineering position very recently. (Very recently: Still don’t know if I got the job) I didn’t get silly brain teasers, but I did get questions about sort algorithm runtimes, and had to write some example code for them. It was not excessively hard, but unlike most of my interviews where I tell them what I know, they actually make you demonstrate it. For an hour. This is the one time where you can answer the question “Where where I ever use this bit of knowledge when I couldn’t look it up online?” Answer: In a Google interview.

They don't have some of the happiest employees. Average software engineer is only there for a few years before they move on. In fact, if you've been there for a while and NOT been headhunted, it sort of looks weird. In any case, it's long hours, and working on weekends is not at all uncommon (I once worked 11 weeks straight without a day off, and many of those were 14-16 hour days). They give you breakfast, lunch and dinner for a reason, you know.
They also aren't the best paid. Google is famous for underpaying their employees. They make up for it with their very generous benefits package. But in terms of straight salary, they're about 20% below other valley tech companies.
By the way, I interviewed a few hundred people for SWE positions while I was at Google. Many of your example questions not only aren't asked, they're explicitly forbidden. You are not allowed to ask frivolous brainteaser crap about manhole covers (there are actually two shapes which won't fall back into the hole, in case you were curious) or why 0xDEADBEEF is 3735928559 in decimal. You don't ask that nonsense because the questions are crap and tell you absolutely nothing about the candidate.
You're supposed to ask open-ended questions that test problem solving and general knowledge, then get into specifics. Once answered, you pick a topic in the answer and you dive in deeper. The goal to to find out where the candidates run out of ideas. Typically you want to test general knowledge, and find an area that you two can really dig deep into. At that point, you send the candidate to the whiteboard and have them start writing code.
So you don't bother with asking questions with simple factoid answers. For example, you aren't going to ask what a mutex is, you're going to talk about them when the candidate's code on the whiteboard has a race condition or whatever.
Similarly, you don't ask "How would you store a million phone numbers?", you ask "How would you sort a million phone numbers on a machine that only had 256KB of memory?" You want to see if they can figure out how to solve the problem creatively given your constraints. And when they write it out, you ask "OK, so that solution is O(n log n)… how can you make it more efficient?" And if they don't know about Big O notation, well then you immediately know you're not hiring that person.
My favorite question was to ask them to write a little program that solved a rubik's cube. It's got a bunch of possible answers and some that I saw were actually quite creative. (The best way, again in case you're curious, is to "open the cube up" and treat it as an asymmetrical grid. You go through it row and column and match up the six colors.)
Some real advice: When given open-ended questions, immediately ask questions in return that would help define the constraints. They want you to sort something, ask if it's a list of INTs, that sort of thing. But the best advice I can give anyone interviewing there is to sharpen your ability to understand engineers for whom English is a second language. Chances are very good that you'll be interviewing with someone who is difficult to understand. Sad, but true.

Well now it’s 2014 and we know why so many Google employees weren’t headhunted – Google is an evil company (just like Apple and others) that engaged in collusion (“no poach” agreements).
So much for “don’t be evil”. I can’t even count the number of times Google has shown to be just as slimy as any other corporation. This cult of personality surrounding Google needs to die. It’s fiction, and it’s always been fiction. Google is not the savior of the tech world. They’re just another corporate giant with selfish interests. Business as usual.
Oh and as far as offering amazing “perks” and having “happy” employees: people are so naive. Paying in “perks” lets you pay less in wages. People stay in their jobs for other factors besides money. If you can buy them off with food, massages, and gym memberships you can pay a lot less in salary
(and, again, you can reduce their salary further by screwing them over by engaging in illegal collusion)

I'm surprised there wasn't the question: Would you, without question, accept micro-chip implantation in your body as a condition to joining Google?
November 24, 2011 at 9:40 pm, notimpressed said:
Yeah, agreed, they probably want you to agree to the microchip implantation out in the parking lot, as a condition for parking your car and getting into the building. Step one: sell your soul permanently for a chance to even possibly get to kiss one g-ass.
The problem with something that is this much of a ‘gotcha’ is twofold.
1. Superman syndrome – if they DO get someone who answers all of the stupidity in the right way, it just means they are ok or well-prepped for specific questions like this. It doesn’t necessarily even mean they are a good coder or whatever else there is to do at google, like
a) code
b) write code
c) code some more on your birthday
d) code all night and weekend
2. This shows me that google is still really a playboy type company in which the founders/leaders have a culture that they permeate, which promotes and condones intimidation of employees. As a potential employee, you are naturally intimidated by some or all of these questions. Even if you are not, it also shows they have a ‘protected club’ type mentality, which will STILL stink up the place once you are inside their prison wall of well fed prisoners.
If anyone at ANY company EVER EVER EVER EVER asks me something like ‘why is a manhole cover round’ or the ‘golf ball school bus’ question, I will say ‘GIVE ME MY GODDAMN RESUME BACK’. Make them HAND you the hardcopy and WALK OUT. Your personal integrity is worth FAR MORE than your salary, or getting to ‘sleep’ (for 5 minutes) in the office while you ‘recharge’ your new-age batteries for 4 more hours after a 12 hour day. Oh. And they can KEEP their swag and shit, too. And I don’t give a FUCK about the food either. ‘Nuff said.
June 22, 2013 at 5:22 am, James said:
Wow. If I were interviewing you, I’d ask, “What’s wrong with Google?” I’d then find your answer highly entertaining, call security, hand you your precious hard copy c.v. and tell you to get off the premises. You have a poor attitude and THAT’S what makes a terrible employee.
November 29, 2013 at 12:35 pm, Scott said:
Already out the door before you call security and I wouldn’t ask, I’d TAKE my resume back. There’s absolutely no reason to tolerate a hierarchy of idiocy. It has nothing to do with having a bad attitude more to do with an unwillingness to tolerate fools and employers that we would all be better off without.

As someone who went through a Google Interview last week, I can absolutely confirm that all of my Software Engineer interviewers asked *this type* of question. Not exactly any of these, but very close.

Gee, the software engineer in test questions seem much harder than the software engineer questions. Seems engineer + test = even more important? Or there were less candidates available from which to compile a more comprehensive list of interview questions in the area of software engineer in test?
June 21, 2013 at 8:24 am, raj said:
I think it’s so because testing sometimes requires higher level skills (especially system-level testing) than coding. The developer writes his or her piece of software and tests if it works as a separate unit; however, when you combine many hardware and software elements into one big system and have to test it, finding causes of problems can be really difficult…

Regarding the Google-Berkshire comparison: when Berkshire was $500 per share, the value of all the shares was less than $1 billion, less than 0.1% of the value of all companies at that time. Over 30 or so years, Berkshire's share price increased by 200x and the company is now valued around $200 billion.
Google, at $600 per share, with 320 million shares outstanding, is already worth about $200 billion. This valuation represents somewhere in the area of 1% of the aggregate value of all public companies in the United States. So for Google to increase by even 10x — without a 10x increase in the stock market overall — its value would need to increase to near 10% of the value of all U.S. companies combined. The law of large numbers makes that almost impossible.

I recently went for a Google interview at their Singapore office. Their were a panel of 4 interviewers all interviews were back to back. I am still waiting to hear as they said after this the results go to a panel I must say I am not sure if I really want to join them as I was not really impressed because:
1. Average tenure of someone in thier staff in existing role is 6 mo. All good for googling but what do you accomplish in this timespan and move on so soon to new projects.
2. I was a bit disgusted because the second interviewer started asking me personal questions as to where I am from. I am a Canadian of Indian origin and I guess he was looking for some Indian accent, then the one that took the cake is when he asked whether I am married to a Chinese. Also wheer do my parents live. he keept bragging he is from Manhattan and trying to get used to Singapore.
3. I could see they are a smart bunch and will be fun to work with. They are a happy lot with some cool perks but I fealt they were becoming very inward looking. This got confirmed recently with the amazon marketplace just announced. Also lot of revenue is still very much tied to search.
I am still waiting but a bit confused if this is the place.

1. You have a stream of infinite queries (ie: real time Google search queries that people are entering). Describe how you would go about finding a good estimate of 1000 samples from this never ending set of data and then write code for it.
and
There is a linked list of numbers of length N. N is very large and you don’t know N. You have to write a function that will return k random numbers from the list. Numbers should be completely random. Hint: 1. Use random function rand() (returns a number between 0 and 1) and irand() (return either 0 or 1) 2. It should be done in O(n).
Solution: reservoir sampling: http://dailyjobquestions.com/2011/10/08/reservoir-sampling/
2. Write a function (with helper functions if needed) called to Excel that takes an excel column value (A,B,C,D…AA,AB,AC,… AAA..) and returns a corresponding integer value (A=1,B=2,… AA=26..).
Solution: http://dailyjobquestions.com/2011/10/12/excel-columns/
3. You are given a list of numbers. When you reach the end of the list you will come back to the beginning of the list (a circular list). Write the most efficient algorithm to find the minimum number in this list. Find any given number in the list. The numbers in the list are always increasing but you don’t know where the circular list begins, i.e.: 38, 40, 55, 89, 6, 13, 20, 23, 36.
Solution: O(log(n)) considering that you can randomly access the elements of the list:
http://dailyjobquestions.com/2011/10/13/circular-binary-search/
4. Maximum sub-sequence, maximum sub-matrix, LCS, LIS:
Solutions: http://dailyjobquestions.com/tags.html#dynamic%20programming
5. There is an array A[N] of N numbers. You have to compose an array Output[N] such that Output[i] will be equal to multiplication of all the elements of A[N] except A[i]. For example Output[ 0 ] will be multiplication of A[ 1 ] to A[N-1] and Output[ 1 ] will be multiplication of A[ 0 ] and from A[ 2 ] to A[N – 1]. Solve it without division operator and in O(n).

Hmmm…..interview questions that don’t really mean anything in their answers – is a bit like fishing in a pond where there are no fish – doesn’t make much sense – try using a good job description and doing good job analysis in your co and not fly by the night wackiness such as this. Ahh – no wonder some jobs remain open for a year or 2 with no veritable success. The hiring manager may as well do the job themselves.

1. There are dogs. Each dog have two parents and some number of children, they have their own cubs, etc. Design a function which checks if two dogs are related in some way (marriage is not counted). Effectievly this means finding a common ancestor in a tree which is not arranged in any way.
2. There are two _sorted_ arrays A and B. Write a function which produces two other arrays X=A-B and Z=B-A where A-B means elements which exist in A but not in B and B-A is vice versa. Complexity is linear to A and B lengths.

What a load of crap. If Google continues down this path to select new employees they will end up hurting themselves in the long term. Right now the bet and brightest are fighting to get into the company so they will tolerate this type of treatment. They would be hardpresed to hire a “wrong” person because they a fishing from a well stocked, highly qualified pool. Like shooting fish in a barrell.
However, bad news travels fast – they are insulting some very qualified people who are going to tell their friends and colleagues about their experience. Pretty soon no one will want to work with a bunch of lunatics and they will have a less rich pool to draw from. They will then have to learn how to actually interview and properly qualify a candidate to select a good one.
Where is the bloody management team there – have they never heard of behavioural based interviewing techniques – do they understand the importance of balance of IQ and EQ.
I guess if you are hiring a bunch of straight coders who can be kept in a room and you throw food in once in a while their methods are ok. For any role in the organization desinged to increase business and move the company forward this type of interviewing is a recipe for disaster.

Apart from CLR and Skiena’s algorithms book, I would recommend the following books focussed on real coding interviews questions which contains great details(real questions with real answers as expected by the google/amazon interviewer):
*Top 10 coding interview problems asked in Google with solutions: Algorithmic Approach By Dr Lin Quan
*Elements of Programming Interviews: 300 Questions and Solutions By Adnan et al.
*Programming Pearls By Dr Bentley
*More Programming Pearls By Dr Bentley
These books helped me greatly in my Amazon’s onsite interview recently.
Practicing topcoders questions can be an additional help if it suits individual interest.

I have been on zero job interviews since I graduated college 12 years ago – I have worked at that same company all this time. So I have no earthly idea what other companies do, but when I interview engineers, I want really don’t care about seeing them answer some “gotcha” mind games nor even seeing that they can implement some obscure algorithm from memory.
Chances are, if you have written a b-tree or any such rudimentary algorithm in your professional life, you’re doing something wrong. For the overwhelming majority of software engineers, you’re using a language that has these structures built in. You need to be able to use the object model or library or whatever it is that you have in your environment, but getting someone to regurgitate how to build tree structure XYZ from college is not a meaningful exercise. In the off chance that you need to write a b-tree in your professional life because for whatever reason the one built in to your language doesn’t meet your needs, you aren’t going to be doing it from scratch – you can have a textbook or Wikipedia article or whatever sitting right next to you. You still don’t need to do it from scratch.
I also hate making someone write something up on a white board while I watch unless it’s something very brief and it’s easier for them to write it rather than say it. It’s a waste of my valuable time to sit there while you write a program on a whiteboard – I’d rather either (a) give you a computer to do it or (b) just sit you in a conference room with a written test and say come get me when you’re done and ready to talk.

For seemingly ridiculous questions like these, they usually want to assess your thought process on how you would solve the problem. It’s not necessarily important to get the right answer, but it’s the process they’re looking for. For example, for the “how many balls will fit in a school bus” what kind of school bus? Standard? Short? New? Old? Some of them have flat roofs, some have rounded. What’s the size of the ball?
As long as you give them the measurements and your logic behind it, that’s what they want to judge.

The rubik’s cube problem is stupid. 99% of the people can’t even solve a rubik’s cube, let alone write a program to solve it? This has nothing to do with problem solving.
That’s like asking someone to play a Beethoven score, when the person doesn’t even know how to play a piano. And how does problem solving have anything to do with it. That’s BS.
When you ask BS question, you will get BS answer. If the interviewer asked me how many tennis balls are in france. I bet you even if i gave a number, he/she won’t know its the correct answer or not. because a BS question will get a BS answer.

Even years later, it’s interesting that this post doesn’t address the single-most important dimension in an interview: “Who, exactly, is asking the question?”
Who is asking the question is at least as important as the question being asked, because how they are evaluating your response is filtered through their own personal lens; which, in turn, determines what response is going to move them; and in which direction.
…Just something to consider in an interview.

The question:
“How many times a day does a clock’s hands overlap?”
should read
“How many times a day do a clock’s hands overlap?”, as ‘do’ is used for the third person singular and ‘a clock’s hands’ is actually plural, refering to the hands, not the clock.

The problem with these questions and the people they’re interviewing are that they only determine tactical, short term problem solving skills and NOT strategic thinking. (Two different things.) Strategic thinking builds new profitable industries, tactical thinking just implements the current strategy. Do they want tactical drones or visionary pioneers as their employees?

Do you know if Google was ever challenged for compliance with Equal Employment Opportunity Commission guidelines concerning the validity and adverse impact of these questions? They do not seem to be professionally developed by psychologists trained in cognitive assessment. I’m guessing these items were never properly analyzed and documented for their validity, were they?
