posted on 3 May 2017
I was interviewed before May 2016.
Interview Preparation Tips
Experience: The test was conducted through Cocubes. It was moderately difficult. Some of the questions are time taking. We need to be decisive in attempting such questions.
Tips: Need to manage time properly. Should assess and choose which questions to attempt and which ones to leave.
Duration: 1 hour
Total Questions: 30
Round: Test
Experience: The three questions are of three different levels.
1. You will be given two numbers. The first one is the starting point and the second one is the ending point of a range of integers. You have to count the number of integers in that range which are divisible by the first number.
Ex : INPUT : 3 18
OUTPUT : 6
2. You will be given a number. You have to find the sum of the digits. If the sum exceeds 9, you have to add the digits of the sum recursively until you a get a single digit sum.
EX : INPUT : 9999
OUTPUT : 9
Explanation: 9999 => 9 +9+9+9=36 => 3+6 =9
3. You will be given an array of characters which include ( L, R , or a number in the range '0' to '9'). A ball is kept on a line of integers initially kept at zero. The ball has to execute the instructions sequentially as follows:
(i) If an 'L' character is encountered, the ;position of the ball has to be decremented.
(ii) If an 'R' character is encountered, the position of the ball has to be incremented.
(iii) If an integer (in the range '0' to '9) is encountered , we have to go to that index in the array and execute the instruction present in that index.
Finally, after all the instructions are executed, you have to print the final position of the ball.
EX : INPUT :
Number of instruction : 5
Instructions: LR1R2
OUTPUT : 3
Explanation :
(i) Initially, the ball is at 0. Since the 0th index in the array is 'L' , the ball moves to 0-1= -1 position.
(ii) The 1st index is 'R' hence, the position of the ball is -1 +1 = 0 position.
(iii) The 2nd index is '1', hence we have to go to index 1 in the array which is 'R', hence the new position is 0+1 =1.
(iv) The 3rd index is 'R', hence the new position is 1 +1 =2.
(v) The 4th index is '2' , hence we have to go to 2nd index is '1' , hence we have to go again to 1st index , which is 'R' hence the final position is 2+1 =3.
Tips: We need to solve all the three the problems to have better chances of clearing this round.
Duration: 1 hour
Total Questions: 3
Round: Technical Interview
Experience: The interview was focussed majorly on coding. It went for about 45min with around 10 coding problems given to solve. Some basics of Computer networking are also tested in this round.
Tips: Be prepared with some basics of networking. As the company's main focus is on Telecom, good knowledge in telecom and networking would be a big advantage.
Round: Technical Interview
Experience: This round was focused on the aptitude and reasoning skills. Some puzzles were given in this round. These puzzles are of moderately complex and are more common ones in interviews. Like the (find the heavier ball among three balls using a balance in min no. of attempts).
Tips: Sometimes the interviewer tries to confuse. You need to be confident with your answers and explaination.
Round: HR Interview
Experience: The interview was more of a traditional HR round. Majorly concentrated on the final year project, personal strengths and weaknesses.
Skills: Coding Skills, Computer Networking, C Language Basics
