8 Questions
- Q1. Program to find the angle between the hands of a clock. Input- the time. Expected output- Angle in degrees
- Ans.
Program to find the angle between the hands of a clock given the time.
Calculate the angle of the hour hand from 12 o'clock position
Calculate the angle of the minute hand from 12 o'clock position
Calculate the absolute difference between the two angles
If the difference is greater than 180 degrees, subtract it from 360 degrees
Return the absolute value of the difference as the angle between the hands
- Q2. How do you find if given two linked lists intersect or not
- Ans.
To find if two linked lists intersect, traverse both lists and compare their tail nodes.
Traverse both linked lists and find their lengths
If the lengths are different, move the longer list's head pointer to the difference in length
Now traverse both lists and compare their nodes until a common node is found
If no common node is found, the lists do not intersect
- Q3. Explain basic concept of JOINS in sql
- Ans.
JOINS are used to combine rows from two or more tables based on a related column between them.
JOINS are used to retrieve data from multiple tables in a single query
There are different types of JOINS - INNER, LEFT, RIGHT, FULL OUTER
JOINS are based on a related column between the tables
Syntax: SELECT * FROM table1 JOIN table2 ON table1.column = table2.column
- Q4. If in a given table, consisting of student name and grade, Output a table containing each grade and its frequency in descending order
- Q5. Questions regarding my final year project
- Q6. SQL queries
- Q7. If you are given a sorted array of size 7 but only 4 elements in it and a sorted array of 3 elements. How would to combine the elements into the first array in such a way that array is sorted
- Ans.
Combine 4 elements of a sorted array of size 7 and a sorted array of 3 elements to make a sorted array.
Insert the 3 elements of the smaller array into the larger array
Sort the larger array using any sorting algorithm
- Q8. How do you find if a string is a palindrome or not?
- Ans.
To check if a string is a palindrome, compare the first and last characters, then move towards the center.
Remove all non-alphanumeric characters and convert to lowercase
Use two pointers, one starting from the beginning and the other from the end
Compare the characters at both pointers, move towards the center until they meet
If all characters match, the string is a palindrome
Interview Preparation Tips
Experience: online test from HackerEarth. It had 3 programming questions, out of which we had to program any two. The questions were: 1) To reverse the words in a given string2) I don’t remember this question properly but was something similar to this…. Finding all the factors of a given number and finding if the one’s position of the factorial and the number were same..
There were 30 other MCQs from aptitude, programming, data structures and algorithms.
After the online test, there were 3 rounds
Round: Technical Interview
Experience: I was given two scenarios to write test cases(apart from UItesting). One was the flipkart coupon textbox from checkout page and the other was the gmail application. He also asked me sql query to remove all duplicates from a table having multiple duplicates.

4 Questions
- Q1. Given a singly linked list, write a recursive method to reverse every 3 nodes in the list. He asked me to inform if I have seen the question
- Ans.
Reverse every 3 nodes in a singly linked list using recursion.
Create a recursive method that takes the head of the linked list as input.

Reverse the first 3 nodes by swapping their pointers.
Recursively call the method on the next 3 nodes and update the pointers accordingly.
Return the new head of the reversed linked list.

Interview Preparation Tips
Experience: On-line Coding Round on Hacker Rank:
1. Given an array of sorted integers which represent box sizes and an integer representing an item size
You have to find best fit box for the item (-1 in case of no box found)
For example:
Given 10,20,30,40,50,60,70 and 45
You have to print 50
Given 10,20,30,40,50,60,70 and 75

Given 10,20,30,40,50,60,70
You have to print 10, 30, 20, 50, 40, 70, 60
At first, I gave answer using sorting. But my interviewer asked me to do this without sorting the input array, and I did it.
2. A simple question on Tree data structure which i don’t remember.
3. Questions related to my project.
Round: TECHNICAL INTERVIEW
Experience: 1. A matrix is given which is sorted row wise and column wise
You have to print the sorted order.

2 3 4 5 7 8
2 3 4 5 8 8
3 4 4 6 8 9
4 5 5 7 8 9
You have to print sorted order

Interview Preparation Tips
Experience: a) Aptitude MCQ (50 questions in 12 minutes), b) Quant + 2 Coding questions (Hackerrank) (45 minutes), c) C/Java MCQ* Aptitude MCQ consists of very easy questions, speed is all what matters here. Attempt all questions (No negative marking).* Quant questions were a bit difficult and took time to solve. For some questions, we had to deduce the answer by checking all the options. Hackerrank coding questions were average.
Line intersection problem and overlapping paintings problem.
” It is important to solve atleast 1 coding problem (3 test cases atleast), to get into the next round. ”
Get familiar with Hackerrank before your interview.*C/Java MCQ questions were average. You had to choose either C or Java. Basic output questions.
Duration: 60 minutes
Total Questions: 50
Round: Technical Interview
Experience: Majority of the students were eliminated after the first round. This round consisted of questions from DS, Algo, OS and Networks. linked list, stack, queue and tree questions were their favorites. Refer geeksforgeeks for questions on these topics (LL reversal, identical trees etc). Also, the interviewer would ask you to write the code for questions on LL, trees etc., so be prepared for it. I was also asked about deadlock, process synchronization, TCP/IP.If you are unable to solve a problem, that is perfectly all right. Don’t give up. Tell the interviewer what you are thinking. The interviewer would help you to reach the final solution.
Round: Technical Interview
Tips: Please don’t write non-sense in your resume,If you have something in your resume, be prepared to back it up.Make sure you know everything about your previous projects.
Round: Technical Interview
Experience: SQL questions were difficult. Study nested queries, joins etc. Again, don’t quit. Try to reach out a solution, interact with the interviewer. They want to know your thought process. I wasn’t able to give the correct/optimal solution of queries and the puzzle, but i was able to dig deep and give a non-optimal solution. Practice popular puzzles.Round 2,3,4 may take upto 1.5 hrs each depending upon the interviewers and candidates. They would know almost everything about you after these 3 rounds.
