Placement Papers - Nagarro

Nagaroo software company visited our campus IIT Allahabad. I am writing this so that it might help others around 290 students appeared for this.

Round 1:

The written round consists of two papers both pen and paper and answers to be fill in OMR. Paper 1 consisted of analytical questions like profit loss, speed, 10th-class geometry problems based questions there was a total of 25 questions. Paper 2 consisted of only coding input/output questions of c there were 20 questions.

Round 2:

There were three questions you have to write only pseudo code for that.

1) Given a starting point in a 2D array of size X Y you have to rotate the subarray of size N starting from the given starting point.

2) There are a lot of strings like "ab", "bc", "cd", "ad" and you have to find the longest string can be made like ab+bc+cd = abcd = 4 (answer) but keep in mind that ending character of first string should be first character of next string.

3) This question also on an array given an array of size m * n. Every row of the array is sorted and contains a unique element but different rows can contain same element present in another row. You have to sort the array and remove the duplicates and store them in 1 1D array.

Technical round:

Cross questions based on the pseudo-code you have written and on their complexities. Then he asked me another 2 questions.

1) Given a string consisting of various words. Reverse all the strings and words by 2 methods.

2) Given a sorted array of size n and there is another array of 2n also contains elements in sorted order. Merge these sorted arrays and remove duplicates if any. The resultant array should also be in sorted order.
Do this by 3 methods.

HR round:

Basic questions like tell about yourself and questions about the project.

I wasn't selected for the reason I also don't know but this might help others. And finally, they selected 5 students.
