Interview Questionnaire 

2 Questions

  • Q1. Why UDP and not TCP in project
  • Ans. 

    UDP is preferred over TCP in this project due to its low latency and lightweight nature.

    • UDP is a connectionless protocol, which means it does not establish a direct connection between the sender and receiver.

    • UDP is faster than TCP as it does not have the overhead of establishing and maintaining a connection.

    • UDP is suitable for applications where real-time data transmission is crucial, such as video streaming or online ...

  • Q2. How would you clear the 7th bit in a 32 bit register
  • Ans. 

    To clear the 7th bit in a 32-bit register, perform a bitwise AND operation with a mask that has all bits set to 1 except the 7th bit.

    • Create a mask with the 7th bit set to 0 and all other bits set to 1

    • Perform a bitwise AND operation between the register and the mask

    • Store the result back in the register

Interview Preparation Tips

Round: Test
Experience: Questions were based on C concepts, given piece of code, find error, output, etc then data structures, bit manipulation, a few aptitude questions were also there (around 5-7).
Tips: Practice aptitude, C, data structures (geeksforgeeks.org is a good source).
Duration: 1 hour
Total Questions: 30

Round: Technical + HR Interview
Experience: I was asked to explain project in detail, I had done projects on embedded, so was asked about that, details like what fields did you use in that structure, why this implementation and not some related other. Memory management, network communications, operating systems. Then questions on C concepts like memory allocation, function pointers, then data structures like linked lists, then bit manipulation in registers. Questions from electrical coursework. Then later, why higher studies, would you still go for higher studies if you had a good job at a company, why etc.
Tips: Be thorough with C (know your Kernighan & Ritchie) and be prepared to go into details about your projects.

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.

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.
