  • Ans. 

    Different types of optical cables include single-mode fiber, multi-mode fiber, and plastic optical fiber.

    • Single-mode fiber: used for long-distance communication, has a small core size and transmits infrared laser light.

    • Multi-mode fiber: used for shorter distances, has a larger core size and transmits infrared LED light.

    • Plastic optical fiber: used for short-distance applications like home networks, made of plastic inste

Round 2 - One-on-one 

(2 Questions)

  • Q1. Process of troubleshooting network issue
  • Ans. 

    Troubleshooting network issues involves identifying the problem, gathering information, isolating the cause, and implementing a solution.

    • Identify the problem by gathering information from users and monitoring tools

    • Isolate the cause by checking network configurations, hardware, and software

    • Implement a solution by making necessary changes and testing the network

    • Document the troubleshooting process for future reference

  • Answered by AI
  • Q2. What tools do you use to check optical fiber
  • Ans. 

    I use tools like optical power meters, visual fault locators, and OTDRs to check optical fiber.

    • Optical power meters measure the power level of the optical signal.

    • Visual fault locators help identify breaks or bends in the fiber.

    • OTDRs (Optical Time Domain Reflectometers) analyze the quality of the fiber by sending pulses of light and measuring reflections.

  • Ans. 

    To make the red fishes 98%, 50 fishes have to be removed from the aquarium.

    • Calculate 1% of 200 fishes, which is 2 fishes.

    • To make the red fishes 98%, subtract 1% (2 fishes) from 99% (198 fishes).

    • To find the number of fishes to be removed, divide the difference by 1% (2 fishes).

    • Therefore, 50 fishes have to be removed to make the red fishes 98%.

Interview Preparation Tips

Round: Test
Experience: There were 40 aptitude questions of variable difficulty. More questions revolved around topics like time and work, distance, speed, time, profit loss, age etc.
Tips: A regular and prior preparation will go a long way in determining a good test score.
Use tricks to solve the questions and calculations should be fast.
Duration: 30 minutes
Total Questions: 40

Round: Test
Experience: The questions weren't that tough when it came to programming. An example would be conversion of temperature from Celsius to Fahrenheit and vice versa. This was a question in my paper. So I'm hoping the difficulty would be more or less the same.
Tips: Do certified programming courses. They help you a lot in cracking good jobs.
Duration: 45 minutes
Total Questions: 3

Round: Puzzle Interview
Tips: This can be tough if you can't imagine scenarios and situations. So make sure you inculcate critical problem solving thinking in your everyday life. I feel that's the best way to do things in this round.

Round: Technical Interview
Experience: This was a short interview so not much happened.
Tips: Whatever you do just know your stuff properly.

Round: HR Interview
Experience: It was a simple interview. Basic questions and their basic answers helped me get through it.
Tips: The tip would be to stay positive in your approach while answering the questions

Interview Preparation Tips

Round: Test
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
