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

Section Difficulty

CS Fundamentals Medium
Aptitude Hard
Coding Hard

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.
