I was interviewed in Jan 2021.
Round duration - 120 minutes
Round difficulty - Hard
This round was very difficult. I never do these much difficulty level of coding questions. But i give my best, and just do every questions by using step by step process.
Given an integer 'N', print an hourglass pattern based on the value of 'N'.
The first and only line of input contains an integer, denoting the value of N.
Print an hourglass pattern based on the given integer 'N'.
Read the integer 'N' as input
Print the top half of the hourglass pattern with decreasing numbers
Print the bottom half of the hourglass pattern with increasing numbers
Handle the constraints for 'N' values between 1 and 50
Given an undirected and disconnected graph G(V, E) where V vertices are numbered from 0 to V-1, and E represents edges, your task is to output the BFS traversal starting from the ...
BFS traversal in a disconnected graph starting from vertex 0.
Use BFS algorithm to traverse the graph starting from vertex 0.
Explore neighbor nodes first before moving to the next level neighbors.
Consider bidirectional edges in an undirected graph.
Output the BFS traversal sequence for each test case in a separate line.
Ensure the BFS path starts from vertex 0 and print connected nodes in numerical sort order.
You are given a stack. Your task is to sort the elements within the stack in ascending order using only push and pop operations. You are allowed to use one additional stack ...
Sort a given stack in ascending order using only push and pop operations with the help of an additional stack.
Use one additional stack to assist in sorting the elements.
Pop elements from the input stack and push them onto the auxiliary stack in sorted order.
Keep track of the current minimum element to maintain ascending order.
Pop elements from the auxiliary stack back to the input stack to get the sorted order.
Round duration - 90 minutes
Round difficulty - Easy
This round is also coding round in this round we have a small video call interaction too, in which hr ask few questions to only those whose coding question is correct.
You are given a palindrome number represented as a string S

Find the largest palindrome number strictly less than a given palindrome number.
Iterate from the middle towards the start of the number and decrement the digits to create the largest palindrome less than the given number.
Handle cases where the number is all '9's by changing the middle digit to '9' and decrementing the rest of the digits.
If the number has an odd length, simply mirror the first half to create the largest
You are given a grid containing oranges where each cell of the grid can contain one of the three integer values:
Find minimum time to rot all fresh oranges adjacent to rotten oranges in a grid.
Use Breadth First Search (BFS) to simulate the rotting process.
Track the time taken to rot all fresh oranges.
Return -1 if all fresh oranges cannot be rotten.
Handle edge cases like empty grid or no fresh oranges.
Tip 1 : Relax and don't stress. Practice
Tip 2 : Build Resume according to Job Description , but don't lie.
Tip 3 : Have good projects and knowledge regarding important subjects related to interviews
Tip 1 : Include only genuine information, never lie in resume , it will impact to bad impression.
Tip 2 : Skills relevant to Job Description
Tip 3 : Resume should not be more than 2 pages
Tip 4 : Have some projects and internship on your resume because it will give good impression
I applied via Naukri.com and was interviewed in Mar 2021. There was 1 interview round.
Start to end approach for regression problem involves defining the problem, collecting data, preprocessing, modeling, and evaluating.
Define the problem and set the goal
Collect relevant data and preprocess it
Choose a suitable regression model
Train the model and evaluate its performance
Fine-tune the model and repeat the process if necessary
Statistics is the study of data. It helps us understand and interpret information by using mathematical methods.
Statistics involves collecting, analyzing, and interpreting data.
It helps us make decisions based on data and identify patterns and trends.
Common statistical measures include mean, median, mode, and standard deviation.
Statistics can be used in various fields such as business, healthcare, and social sciences.
