For the last couple of days Satya and I have been interviewing rookie programmers - people with less than one year experience for a certain activity we are going to get into. We are not particular that they should be Engineering graduates, or MCA etc. But you find them everywhere and we have received resumes of people with either an Engineering degree or an MCA. They have completed their last degree just an year back.
After talking to them on other things, we ask them to solve a few simple Math problems. This is really revealing. I give below the questions.
One candidate with a B.Sc (Comp) and MCA couldn't solve a single problem above. His answer to the first question was "1". In fact three candidates all gave "1" as the answer to the first question. Then on further prompting and helpful hints, one came up with 1.4, another 1.414. One person came up with an amazing method, which resulted in sqrt(35) reaching close to 12.xxx. No one could touch the quadratic equation. One candidate solved all but the last problem.
The degree we are giving out is worth shit.

Dear Mr. Badri,
ReplyDeleteWhat ever said and done ultimately companies in india want only people with degrees to be employed in their company. BE and MBA combined or done individually are much preferred. May be people like you should make companies focus on real talent of a person rather than evaluating them on some paper

Badri, When i used to do management round interviews for my company, i ask them basic questions like
ReplyDelete1. Why manhole cover is round and not square
2. Why do bus stops are not exactly opposite and stuff like that.
Most of the time. these kids can't even think.
And regarding algorithm. if i ask queries like algo for lifts in a building, they go blank. I never want correct answer. I want them to try. But it rarely happens.
Did u happen to read the below link?
ReplyDeleteSame thing happened in an Engineering college in Erode, where second and third year students were not even able to say Newton's first law of motion. It was so shocking...

Quadratic equation has a simple formula which is taught in Class 11. How can college graduate say they didn't know it?!
ReplyDeleteSaravanan
Do they need to know this, for what they have to learn to do YOUR job ? Just train them and get on with life man !!
ReplyDeleteBadri,
ReplyDeleteIts not that our educational system is shit,we don't teach anything practical thats the issue.Where would the normal guy use the square root of two in his day today life.Did we teach the practical application of calculus?or the importance of it? guys who applied calculus in their career have grown leaps and bounds.Without the practical knowledge everything is memorized and people,including you, expect the memorized answer :) (square root of 2 in this case,you didn't ask them to derive it ,you just asked the answer).Other than that ,I am a great fan of yours :) .
With all due respect to you, I believe your questions were a misfit for most programming jobs in the Indian IT industry. I do not know about your specific job requirement but I do not think that solving all the above questions would make someone a good programmer for today's Indian IT sector requirement.
ReplyDeleteHypothetically, if you are interviewing for a web programmer role, you should find out if he knows what is Javascript, How to control your presentations aspects such as color (CSS) ? which libraries should you use if I want fluidity or colorful buttons or touch friendliness etc. What is usability ? What is Fitts' law ? How to make mobile friendly sites (awareness of jquery mobile) ? Which javascript libraries you have used ?
Hypothetically if you are hiring for a kernel programmer, then ask about, What is memory management ? What are memory maps ? What is paging etc. ?
Unless you are hiring someone for doing some core algorithms work, such as in routing or cache management etc., then you can ask math questions. But for most common UI side programming work, math knowledge is not needed. May be because of your IIT lineage you have high expectations about Math from students even though it is practically useless for most jobs in the Indian IT industry.
If you are really interested in Math based programming, you should check out http://en.wikipedia.org/wiki/Functional_programming
> Unless you are hiring someone for doing some core algorithms work, such as in routing or cache management etc., then you can ask math questions.
Deleteoops. Excuse the mistake above.
Note to self: Never comment on a post while watching tv
Regardless of the job, I would have been asking these questions, because this is about problem solving. I would have expected an answer fuzzily rather than accurate. Because accuracy is not important that a calculator would do. I would expect "1+", close to 6 but not 6, doesn't have roots as the answers that I prefer.
DeleteHere is my take. If you take a diverse set of successful people, with 20+ years experience, in a variety of areas (pick engineers, lawyers, sales people, business people, doctors, real estate brokers, musicians) and give these tests, you will be surprised at the results. In my experience (yes, I have done such a test!), about 25% will flunk this, and yes even some practicing engineers.
ReplyDeleteMathematical poverty (my phrase for it!) seems to run far and wide, across all cultures, across social strata.
One reason may be that people simply forget mathematics quickly. It is something to be endured in school and quickly forgotten.
I have speculated on how we could teach mathematics better. I would focus on building simple models of real world phenomena, making people estimate quantities. Like "at the speed at which we commute in Chennai, how long would it take to go to Bangalore" to "How much petrol per person do we consume in Chennai?" "How many years does it take to double money with 12% compound interest?"
I would introduce building spreadsheet models.
Coming up with models and estimates, building spreadsheets, is far better (IMHO) than memorizing the solution for quadratic equation (to be perfectly honest, I am not sure I can reproduce that solution right this second, it has been a long time!).
Sridhar: One of the questions above is yours - you would have recognized this. We have discussed your views on this a few times. I do agree with you that context would help doing Math better. I was trying to get some degree of aptitude on the part of the candidate. Quadratic equation is the least relevant to the work going ahead, but we wanted to throw that to find out if someone even answers that by remembering how to solve them.
DeleteYou have more of an experience in hiring programmers. I am starting out now:-) So will learn the ropes as we go along!
Dear Dr. Badri and Sridhar: I have tested 1000s of students from all streams, Engineering, Arts, Sciences, etc. More than 90% of the students won't pass in 8th grade Maths. Leaving aside quadratic equations, they can't answer even questions such as "What is 50% of 50% of 50%?", or "1/2+ 2/3 + 3/4". So it's not just quadratic equations which is the villain.
DeleteTake even the case of very simple Applied Sciences. Tell them "You have a bucket half full of water. You want to transfer it to another bucket using a flexible plastic pipe. You have no pump. How do you do it?"
If they had learnt the answer by discovery, applying their minds, they would have learnt to apply the learnings, later in life. We just 'teach'; we don't let them learn. Please see my separate post on how, I believe, this problem can be addressed.
One company is recruiting school students (+2) (but don't know what kind of role they are playing) . +2 qualification is enough to work in IT as a Developer/Designer/QA......
ReplyDeletecan you give me company name .I was a BE graduate who was not able to complete graduation but somehow managed to get into a IT based company outsourcing a client in U.S .even with 3years of experience I am underpaid due to lack of graduation Remember this is India not U.S
DeleteThat is www.zoho.com
DeleteBadri,
ReplyDeleteFor the last problem you would have given a hint to use quadratic formula, they might have solved the problem :)
x = [-1 ± √(1 - 4)]/2
x = [-1 ± √(-3)]/2
x = (-1 ± i√3)/2
where i = √(-1)
The solutions are:
x = (-1 + i√3)/2
x = (-1 - i√3)/2
Probably one can give a hint as (x+1/2)*2 +3/4=1

ReplyDeleteChinese students in college are excellent at academics; I know this for a fact. They have other weaknesses, like lack of communications skills in English and not being well-rounded.
DeleteBut that apart, even if we were to re-phrase it, we could ask, 'Did Kamaraj solve all these problems to become a great CM?" The answer is, one Kamaraj is great, but a State or nation full of Kamaraj's would be a disaster.
I completely agree with Badri. If people cannot solve simple 6th grade math problems, then the degrees are actually worth less than shit. In fact their degrees should be revoked.
ReplyDeleteR.Srinath, seetheavatar, Sankar P : Are you guys serious? If you cannot solve addition of simple fractions, how would you create new algorithms?
It is disappointing to see an engineer and businessman like Sridhar Vembu echoing similar sentiments, albeit using different words. If a person cannot solve 2x + 7 = 17, how would they compute the time taken to go to Bangalore? Both of them are linear equations.
I shudder to think what kind of answers they would have given in their exams. Now, I'm even more curious, what kind of questions are asked in their exams?
In our continuing saga of interviews, today, one candidate looked at 2x + 7 = 17 and in no time answered x=5. I was amazed because he had completely screwed up the previous questions. So I followed up with asking him to solve 2x + 17 = 23. Now he was stumped. He took more time and kept on guessing. At that point Satya introduced an even more complex problem 2.6 x + 4.6 = 1.9 x + 13.4. You would be amazed to know that now the chap correctly went ahead, moved x to one side and the constants to the other side and ended up with x = (8.8/0.7).
DeleteNote that we were not particularly concerned about the right answer. We only wanted to find out how he approaches the problem. We asked him how he could do this more complex problem and was stuck for a relatively simple problem and he couldn't explain this convincingly.
To me, education and skill building is a much larger issue. We may or may not get the employees we desire; and these people we have interviewed may find far better companies that pay them much more than what we may ever pay. The issue is not this at all. I have been visiting a number of Government schools to understand about their reading and comprehension ability in Tamil. I have taken many videos and am analysing them to find out why in a class one or two read well but most cannot. I will now add the math-ability and try to understand what is being taught and why most of our children struggle.
i am a practicing surgeon and the last time i did any maths was maybe around 20 years ago (adding up my bill total -not counting)....and i could do all 5 of the above with ease.......and i can only come to one conclusion....படிகறப்போவே நல்லா படிச்சு இருந்தா....
DeleteTamil Nadu State Board exam papers in math contain ONLY questions that are in the textbooks, without even a change in the figures, so pupils memorise the problems with solutions, without any need or effort to understand. The better mugger scores more. Most of the teachers themselves do not know how to solve them, they just copy from their notes or recall from memory.
ReplyDeleteAnother peculiar feature is that the 11th Std syllabus is not included for the school final exam, so the examinees do not even memorise the solutions of the problems in that. First year engg students do not know calculus because it was there in the 11th Std.
As a retired math prof I do not know what the IT industry requires of their trainees. But the way teaching is done, the thinking faculties are totally blunted at school. The better students pick them up by the end of the first year, I suppose.
It may surprise many that even scholars applying for doctoral programmes in math are deficient in fundamentals. I have met some Ph D holders from Bihar (in the Middle East) totally ignorant.
Dr R Narasimhan, Chennai
It all starts with school education. Recently from one of the top university(sic) in TN out of 100+ could score more than 5 marks out of 30 in aptitude test. Worst news is that these colleges engage soft skill trainers in all 4 years of engg studies to teach students elementary maths and English. In the past 3-4 years less than 15-20 students get selected from TN for NIT on all India merit quota.
ReplyDeleteThe accent in TN is in social justice, which aims to bring down the urban students' level to the level of rural ones. But I do not understand why students from CBSE stream in TN do not perform as well as students from other States, esp. Andhra in national entrance exams. TN govt opposes any sort of common entrance test at the national level, fully realising that their students are ill-equipped. However, reservation helps TN candidates to perform well in Central Services exams, with extra coaching.
DeleteI am appalled at the responses of R.Srinath, Seetheavatar, Sankar P !
ReplyDeleteIf an Eng. graduate can't solve these simple questions, there is some serious 'problem'!
Dear Dr. Badri,
ReplyDeleteIMHO, if we make the following 3 basic changes in our education system, we can improve the quality of our education substantially:
1. Have a re-look at what we teach
2. Have a re-look at how we teach
3. Have a re-look at who teaches.
Let me explain:
1. Life Skills must be integrated into education. This will include building integrity, communication skills, inter-personal skills, team skills, mind skills, social skills, decision making skills, finance skills, etc. which can be included from classes 5 to 12 (or at least up to 10). All of these would required only about 5% of the periods. (I have a detailed model for this, already well tested substantially.) If we have to sacrifice a few lessons in English, higher Math, Science etc., it will be worth it. From your blog, it is clear that most of the children haven't learnt even the basics of these anyway.
2. How do we teach any subject? Teachers typically take up each topic and start teaching. For example, when they teach about Circles, they say, the 'Circumference of a Circle = Pi X D; Area = Pi X D^2/4'. At the end, ask students 'What exactly is Pi'? At best, they will say, it is 22/7 or 3.14. How many students will say 'there is a certain fixed constant relationship between the radius of a circle and its diameter, regardless of whether the circle is small or large', and this constant has been found to be about 3.14 or 22/7, and it is called Pi'? How may teachers are capable of giving this explanation?
We need to introduce each topic, starting with questions. for example, while teaching about circles. Give them a few circular objects, and ask them to measure the diameter and circumference using even crude methods. Ask them if the circumference and diameter are related, and how. Let them discover it. Let them debate it in groups and explain it in the class. Now, their understanding will be better and long-lasting. Most topics can be taught this way. Some topics will require higher level tools than we use.
3. Most teachers are ill-equipped to teach, but they can be trained to be Facilitators. If we produce video based teaching material, with delivery by top class expert teachers, and use these as short clippings in the Class, every student will have the benefit of teaching by top notch experts. We can train teachers to raise questions, get students discover learnings by themselves, show the Clippings, and clarify (at least to standard questions), the learning will be far better and long-lasting. All this won't cost a bomb; in fact, if we think creatively, we can even reduce the present cost of school education.
All this applies equally to college education including Engineering education.
If we do all this, and use Life Skills to give self esteem to every child, we will also have far fewer dropouts and failures. Very few students will be left behind.
Most the systems around us, be it homes, hospitals, shops, factories, etc. have changed over the years, but not the way we teach in schools and colleges. It is possible to change things, if people in power are willing.
At least, experimentation can begin with schools being given the autonomy to try out such experiments, but without having to suffer -non-recognition'.

ReplyDeleteStudents or parents should never forget the categories numbers (whole number, fraction, irrational), the concept called variables and solving equations is all about school maths or engg problems. One need not think it is teasing of job seekers. One has to review all the time their learning objectives and the service goals. Employers should assist in providing for the same before the get their selections!
