  • Ans. 

    A diplexer is a device that separates or combines different frequency bands, while a duplexer is a device that allows two-way communication over a single channel.

    • Diplexer is used to separate different frequency bands in communication systems.

    • Duplexer allows two-way communication over a single channel by separating transmit and receive signals.

    • Example: Diplexer is used in satellite communication to separate uplink and d...

  • Q3. Phase delay vs Group delay
  • Ans. 

    Phase delay is the time difference between input and output signals, while group delay is the rate of change of phase delay with respect to frequency.

    • Phase delay is the time delay experienced by a signal passing through a system, while group delay is the derivative of phase delay with respect to frequency.

    • Phase delay is constant for all frequencies, while group delay varies with frequency.

    • In audio systems, phase delay ...

  • Q1. Related to semiconductors, processors etc. were asked.
  • Q2. Strength
  • Q3. Weaknesses
  • Q4. Hobbies
  • Q5. If there are 200 fishes in an aquarium. 99% are red. How many fishes have to be removed to make the red fishes 98 % in the aquarium?
  • Ans. 

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

    • Calculate 1% of 200 fishes to find the number of red fishes.

    • Subtract the number of red fishes from 200 to find the number of non-red fishes.

    • Calculate 2% of the total number of fishes to find the desired number of red fishes.

    • Subtract the desired number of red fishes from the current number of red fishes to find the number of fishes to be removed.

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 Questionnaire 

3 Questions

  • Q1. They asked me optimise the code I had written for the first question
  • Q2. Given a binary tree, find out the maximum sum path from root to leaf. This problem, but they said tree has only positive integers. -----/ . To store the path I had used global array. They asked me alternat...
  • Q3. Given a list of words. Given three operations find out the minimum steps to reach from source string to destination string. Basically, -----/ this is the problem with some modification. For this question I...
  • Ans. 

    The question is about finding the minimum steps to reach from a source string to a destination string using three operations.

    • BFS and DFS are graph traversal techniques that can be used to solve this problem.

    • BFS is typically used when finding the shortest path or exploring all possible paths in a graph.

    • DFS is useful when searching for a specific path or exploring deeply into a graph.

    • In this case, BFS can be used to find...

Interview Preparation Tips

Round: Test
Experience: • 1 question was on time complexity of searching an unsorted array.
• 2 questions were on recursion, ie, number of recursive calls.
• 1 question on analysing given function on string.
• 1 question was on probability(Two hotels, say A and B. Probability of moving from A to B is 2/3, staying at A is 1/3. Probability of moving from B to A and staying at B is 1/2. If they make decisions each hour, and if they were at A at 7:00 pm, what is the probability that they will be at B at 10:00 pm).
• If a set has elements {1,2,3,4 .... n}. Then what is the sum of elements of it's power set. (Ex: S = {1,2}. Then power set is {{},{1},{2},{1,2}}. The sum is 6.
• If a set has elements {1,2,3,4,5,6,7,8,9,10}. Then how many subsets of 3 elements has no consecutive elements.
• 1 question was on designing a DFA for a string starting with a and ending with c and has at least b in it.
• 1 question had machine instructions. We had to find out minimum number of cycles needed to execute the given set of instructions. (a) If the instructions are executed in the given order. (b) If the instructions are executed in random order.
• 1 puzzle on bridges.

Tips: In this round they not only see the answer. They also verify how you approached(So, give correct explanation to your answers).
Duration: 90 minutes
Total Questions: 10

Round: Coding Round
Experience: Two questions were there. 3 hours duration.

1. Long question, I don't remember fully. I'll just give input/output examples. It was basically on string decoding. If jon2snow3 is there the decoded string will be jonjonsnowjonjonsnowjonjonsnow. Given a string and an integer k we have print the kth character in the decoded string
input:
jon2snow3
8
output:
n

2. Given an array and an integer k return the number of contiguous sub arrays whose sum is divisible by k.
input format:
n k

input:
4 5
10 0 4 5

output:
4

explaination: {10},{0},{10,0},{5} are the sub arrays with sum divisible by 5.


Tips: You will have lots of time, so try to optimise the solution if you can. Remember here also they review each individual's code.

Round: Technical Interview
Experience: They will help you a lot if you are stuck at some point in the question. You have to be smart enough to grasp the clue.
Tips: They only ask questions only on data structures and algorithms.

Skill Tips: You have to be strong in coding. Algorithm questions will be mostly on dynamic programming. Data structures questions are mostly on trees.
Skills: C Programming, Maths(esp Probability), Algorithms And Data Structures
