Webyog Interview Question 2014

Hi Guys,

I know its been ages since i last updated this blog. Thanks to a reader I finally have sat down to do a new post. I have another first hand account of webyog interview, this time from a reader who sat on  14th Sept 2014. Here is what she commented on the last years post i paste it here as it is.

I have written the webyog test on 14th sept, 2014. There was no question related to aptitude. Questions were as follows:

1. Which feature in C/C++/Java you don't like? Give a suggestion to make it better.

2. What is class? How classes help into improving programing.

There were 8 questions from coding. Each two were from C, Java, Java script and Dot net. You have to attempt any 4 questions.

3. Search and remove a particular node from linked list. (C/C++)

4. If a user enters any number then you have to print the English name of that number.
example : 1 -> one
                   120 -> one hundred twenty
                   8760 -> eight thousand seven hundred sixty

5. What is the best way in java to search and remove duplicates. Give a sample program.

6.Given two arrays : {1,2,3,4,5} and {2,3,0,1,5}
Find the element in second array which is not present in first array in java.

7. ) delete the duplicate words in the following sentence in java script
     this is is very very good


I only could remember these question. There were 10 questions total. Time duration was 60 min. Thanks

 I have decided to do a new post for this so that its more accessible. And Special thanks for my special reader. Read, Learn and Share

Last years questions are still available here Webyog interview questions

eLitmus Software Developer interview questions

I'm back once again, and in this post i'll be sharing Question asked in the first round of recruitment drive held by eLitmus for the post of Software developer. This paper is purely memory based and only one set, whatever I had access to when I sat for this drive.

Hope you find it useful. Here it goes...

eLitmus Interview Questions

1>     Write an algorithm to reverse an String word by word (Not character by character) E.g. Given String is “I work for eLitmus, and I am 21 years old!”

Output should be : “o ldye ars amIande, Lit m us 21 forwo rkI!”

Description: only alphabets should change their positions , special characters should retain their initial positions.

There are to methods give is_alphabet(char) returns true if char is alphabet

And reverse(String)    reverses the string like “eLitmus” becomes “sumtiLe”

2>     A puzzle which was very confusing I didn’t understand a thing.

3>     There are five dices to display dates like 17APR

Face having 6 is used interchangeably for 6 and 9. Letter dices have letter without repeat to display all months in that format except Aug which is represented by VAC

Find all digits on dice having 6 and all letters on dice having letter L

4>

Three table having relational database of movie reviews. We have to write two SQL queries both involve join and one self-join.

5: Which data base will be best suited for storing recent History in a web browser. Justify your answer.

6: pre order to post order binary tree 

Technology JK

7: which online portals you use to keep yourself updated with technical news. List all.

8: List open source technologies developed by a) Facebook b)Google apart from android c)Oracle d)Twitter e)Microsoft

9) Which of these is not a mobile OS a)Bada b)FirefoxOS c)WebOS d)PhoneGap e)Symbian

 Keep checking back for more. And  dont forget to like, share and comment or else I might end up not bothering with updating my blog.

Peace.

 

Reversing string in c using pointers

#include <stdio.h>
#include <string.h>

void print_reverse_string(const char *str)
{
    const char *src = str + strlen(str);
    while (src > str)
        putchar(*--src);
}

void reverse_string_and_print(char *str)
{
    char *src = str;
    char *end = src + strlen(src) - 1;
    while (end > src)
    {
        char t = *end;
        *end-- = *src;
        *src++ = t;
    }
    //return str;
   printf("%s", str);
}

char* reverse_string(char *str)
{
    char *src = str;
    char *end = src + strlen(src) - 1;
    while (end > src)
    {
        char t = *end;
        *end-- = *src;
        *src++ = t;
    }

   return str;
   //printf("%s", str);
}

int  main(void){

    char data[50]= "";

    printf("Enter any string:\n");

    gets(data);

    printf("%s\n", data);
    printf("%s \n", reverse_string(data));
    printf("%s\n", data);

    return(0);
}

I have written the abbove code to reverse an string using pointers. I assume that the above code is self explanatory but still if you want any clarification use the comment section below post.

Peace.

e Litmus pH test exposed II

Sorry for the delay. I promised to do a post on complete procedure of eLitmus but the wait is finally over. In this post Ill reveal the entire procedure of how you get job through elitmus.

So here it goes...



The first thing you have to do is register yourself  with elitmus on their website.

Next step plan a test. Test are conducted in all major cities across India with an approx frequency of around one a month. Test fees is Rs 750 at the time of publishing this blog.

eLitmus

 

Now comes the real issue. You have to prepare for the test. The test has three parts;

1. Verbal Ability
2. Problem Solving
3. Quantitative Aptitude

Now the problem is that I cant help you much with the preparation part. Why? Well I took the test without any preparation. On the elitmus forum is written that the test has difficulty level of CAT but I didn't find it difficult at all. Thats that, find your own ways for preparing. And if you as brave as me you can head to the examination hall without any preparation.

Now come the question hows test conducted.

I took the test in Calcutta center. Ill be describing how its conducted there. The procedure might differ in some other center.

Once you have paid for the test they'll email you your admit card which will be a password protected PDF. All the information related to test like venue timing etc will be given in that.

My tets was conducted in St Xavier, Park St, Calcutta. Most of the procedure is same as any other test. Its a 2 hours test. And you'll not be allowed to go anywhere in those two hours. So make sure you're done with all you needs before sitting for the elitmus test. ;)

As I told you it has three section, each section has 20 question. And yes there are negative markings as well. But its a little lenient. You marks wont be deducted unless  more than 25% of question in a section are wrong.

How much do I have to score to qualify?

For Quantitative aptitude and problem solving; doing 8 questions correctly will guarantee around 95 percentile. You'll be on cloud nine with that score.  For Verbal reasoning 15-16 out of 20 will be enough.

If you get that much you'll be getting interview calls from almost all companies that recruit through elitmus.

I have seen students with less that 90 overall getting calls.

One thing you need to make sure is that you score over 80 in all sections.

Thats it for the elitmus pH test.

What happens after that?

eLitmus

Companies call you for recruitment drives, which are very similar to drives conducted in college campuses.

In upcoming posts Ill be talking about how the drives are conducted. Obviously Ill only be discussing the once I have attended.

If you want some more info don't feel shy while commenting.  

Later.

eLitmus pH test exposed

If you have ever wanted to know how is the eLitmus pH test conducted, you must have by know realized that find proper info is just impossible on the internet. I have tried Google, I have tried Bing, I have tried Yahoo and all I could, I have exhausted reading the eLitmus forum, all in vain. But the good news is that I have taken this test and know I know it inside out.

I am planning to do a complete spoiler of eLitums pH test but….. Ill wait till results are out. Only then you’ll get to know the firsthand experience.

Till then keep waiting and if you are really desperate let me know, ill try to hurry it up. 

elitmus pH test has been exposed in this post.
