There were 2 sections of the test.
The timings of the test are usually in the morning only.
In the first section, there were generally mcq - based questions and then there was a coding round!
After clearing the rounds you will get mail for the interview. First will be your technical one and then the HR interview.
The interviewer was good, but he actually asked me aptitude questions and then gave me two code to write. Overall it was a good experience.
1. Leap Year
Easy
15m average time
80% success
0/40
Asked in companies
You are given a year in the form of an integer 'N', and your task is to check whether the given year is a leap year or not.
Note:
1) A year is said to be a leap year if it has 366 days. Normal years have 365 days.
2) The integer 'N' does not contain any leading zeros.
Problem approach
I actually coded it in python. The steps were pretty simple as:
Step 1 : You first need to take the input
Step 2 : Then apply the condition to find whether it is a leap year or not.
Step 3 : Then print it accordingly.
2. Armstrong Number
Easy
15m average time
85% success
0/40
Asked in companies
You are given an integer ‘NUM’ . Your task is to find out whether this number is an Armstrong number or not.
A k-digit number ‘NUM’ is an Armstrong number if and only if the k-th power of each digit sums to ‘NUM’.
Example
153 = 1^3 + 5^3 + 3^3.
Therefore 153 is an Armstrong number.

It was an interview round. My interview was in the morning. The interviewer was a good person, not that strict.

Moderate
10m average time
90% success
0/80
Asked in companies
You are given a positive integer 'N'. Your task is to return all the prime numbers less than or equal to the 'N'.
Note:
1) A prime number is a number that has only two factors: 1 and the number itself.
2) 1 is not a prime number.
Problem approach
Step 1 : Take two integer inputs as low and high limits of the interval,
Step 2 : Run a for loop to iterate through all the numbers.
Step 3 : Run a Nested for loop to check for prime or not.
2. Left View Of a Binary Tree

Asked in companies
You have been given a binary tree of integers. You are supposed to find the left view of the binary tree. The left view of a binary tree is the set of all nodes that are visible when the binary tree is viewed from the left side.
Example:
The left view of the above binary tree is {5, 7, 14, 25}.
