MNR Educational Trust Maths Teacher Interview Questions and Answers

Interview preparation tips for other job seekers - I don't think I can reveal the questions but I can tell you that KLA has high standards in interview process.
Some tips for software engineer interview
1. Please prepare to do competitive programming like use leetcode algoexpert hacker rank
2. Some of the important areas are string problems dynamic programming stack based and tree based
3. There can be design round and interesting questions may be encountered

Round: Test
Experience: This round was simple.
It consist of 5 sections ..1.Aptitude (10 questions). 2.Operating System Basics and Unix Commands(16 questions) 3.Data Structure(9 questions) 4.Output C Questions(6 questions) 5.Programming questions out of 4 any 2 you can do.(2 questions from data structure and 2 from sorting)
Tips: If you know the basics of all these topics then you can easily clear this round.Try to score as more marks as possible because this score counts in the next round too.

Round: Technical Interview
Experience: Moderate
Tips: Be confident and don't get panic.If you don't know anything simply say no don't waste time.

Round: Technical Interview
Experience: Moderate

Skill Tips: Be Confident and keep calm.You must have the complete knowledge of the projects which you have written in your resume.
Skills: C, Data Structure, os, Database
College Name: VIT VELLORE

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
Duration: 5

Duration: 1 hour
Total Questions: 20

Round: Coding
Experience: Given two questions. Each question is written like a story, but once you get the idea, it will be a simple question

Interview preparation tips for other job seekers - Mostly DS and Algo rounds followed by design rounds. Sometimes there can be language specific questions.

Interview preparation tips for other job seekers - Girls and ladies please don't join this company as it is more into priest kinda,they check your caste,class rather your hardwork it seems. This so called senior recruiter totally flirts with you if you are single,divorce,seperarated and also heard his eyes rolls on always girls upper part,no matter whatever she is wearing. I heard after complaining also higher authorities didn't taken the action. Now you people only imagine how is it safe for a girl to work in that disgusting atmosphere.

They are not giving you secured job,HR are saving there job to close that position and you are bakra,who will be paid with very less salary comparative outside and also you are treated like a dog. Think twice thrice to take the decision.
