Intuitive AI / Cloud -- Campus Placement Online Assessment Experience

Intuitive AI / Cloud recently visited our campus for placements, and I wanted to share my Round 1 (Online Assessment) experience to help others preparing for similar roles.

Round 1 Structure

The first round was conducted on an online assessment platform and consisted of three sections:

1. CS Fundamentals -- 15 Questions

This section included MCQs from core computer science subjects such as:

• Operating Systems
• DBMS
• Computer Networks
• OOP Concepts
• Basic Data Structures

Some questions were also Python-based conceptual questions, testing basic understanding of Python syntax and behavior.

The questions were mostly conceptual and moderate in difficulty.

2. Aptitude -- 10 Questions (Hard Level)

This section included:

• Quantitative Aptitude
• Logical Reasoning
• Probability-based problems

Most questions were time-consuming and tricky, especially the logical puzzles.

Difficulty: Hard

3. Coding Section -- 2 Questions

In the coding section, we were allowed to choose from the following languages:

• Java
• C++
• Python
• JavaScript

Coding Question 1 (LeetCode Hard)

Number of Visible People in a Queue

https://leetcode.com/problems/number-of-visible-people-in-a-queue/

The problem asks to determine how many people each person can see to their right in a queue based on heights.

A person can see another person if all people between them are shorter than the minimum height of the two.

The optimal solution uses a Monotonic Stack to efficiently process the heights.

Difficulty: Hard

Coding Question 2 (Scenario-Based Problem)

This problem was based on a room ordering / exam redistribution scenario.

Problem Summary

Linda collects exam papers from different rooms and redistributes them for peer review. The students are located in multiple rooms with different sizes.

Process

1. Linda starts from the first room and collects all exams.
2. In each next room, she distributes exams from the top of her pile.
3. Then she collects the newly written exams and puts them at the bottom of the pile.
4. After visiting all rooms once, she returns to the first room and distributes the remaining exams.

Constraints

• Linda must never run out of exams while distributing.
• No student should receive their own exam.
• We must determine a safe order of visiting rooms.
• If no valid ordering exists, output "impossible".

Example

Input

4
2 3 3 1

Output

2 3 4 1

This problem required greedy reasoning and ordering rooms based on the number of students.

Difficulty: Hard

Other Coding Questions Asked to Friends

From discussions after the test, it seems that the coding questions were randomized, but most were hard-level LeetCode problems.

Some questions asked were:

1. Minimum Insertion Steps to Make a String Palindrome

https://leetcode.com/problems/minimum-insertion-steps-to-make-a-string-palindrome/

Concepts involved:

• Dynamic Programming
• Longest Palindromic Subsequence (LPS) / LCS variation

2. Best Time to Buy and Sell Stock IV

https://leetcode.com/problems/best-time-to-buy-and-sell-stock-iv/

Concepts involved:

• Dynamic Programming
• Transaction-limited stock trading problem

Overall Difficulty

The coding questions required strong knowledge of:

• Monotonic Stack
• Dynamic Programming
• Greedy Algorithms

Overall, the round was quite challenging, especially the coding section.

Hope this helps anyone preparing for Intuitive AI / Cloud interviews.
