AI Pattern Synthesis — All Roles Overview

Track: Intern

SDE Intern

Online Assessment (OA) Round

Format: Proctored online assessment with 2 coding questions of medium-hard difficulty.
Questions Asked:
1. String manipulation with character swaps based on a matrix of pairs (e.g., swapping characters in a string based on predefined matrix transformations).
2. Snake and Ladder problem (similar to LeetCode 1222).

Technical Interview

Duration: 90 minutes.
Format: Live coding on a shared editor.
Questions Asked:
1. Finding the second maximum element in an unsorted array (single traversal, handling duplicates).
2. Finding the majority element in an array (LeetCode problem).
3. Knapsack-like DP problem (Coin Change II) (e.g., LeetCode 518).
Discussion Topics:
- Time and space complexity analysis.
- Data structures (e.g., unordered_map).
- OOPs concepts, method overloading, call by value/reference, and pointers.

Managerial Interview

Duration: Typically 30-45 minutes.
Focus Areas:
- Personal coding journey and growth.
- Project details and challenges faced.
- HR-related questions (e.g., "Why should I hire you?", "Why do you want to join NI?").
Interviewer Profile: Senior NI employee with ~16 years of experience.

Key Takeaways for Preparation

Algorithms: Focus on arrays, strings, dynamic programming, and graph traversal (e.g., BFS for Snake and Ladder).
Data Structures: Prioritize hash maps, arrays, and trees.
Problem-Solving: Practice single-pass algorithms and edge-case handling.
Behavioral: Prepare to discuss projects, challenges, and alignment with NI’s values.

Summary Log:

Cleared all rounds and was selected for the SDE Intern role at National Instruments. The process included an Online Assessment, Technical Interview, and Managerial Round, all completed within two days.

Online Assessment (OA) Format:

Online Assessment Round conducted in a proctored manner. Consisted of 2 coding questions with medium-hard difficulty level. Questions included: 1) String manipulation with character swaps based on given matrix pairs, and 2) Snake and Ladder problem (similar to LeetCode problem).

Reported Round Breakdown:

• Online AssessmentMore Online Assessment questions

Online Assessment Round with 2 coding questions. First question involved string manipulation with character swaps based on a matrix of pairs. Second question was a Snake and Ladder problem.

Questions Logged:

String manipulation with character swaps based on a matrix of pairs
Snake and Ladder problem (similar to LeetCode problem)

• TechnicalMore Technical questions

Technical interview lasting 90 minutes. Included live coding on a shared editor. Three coding questions were asked: finding the second maximum element in an unsorted array (single traversal), finding the majority element in an array, and a knapsack-like DP problem (Coin Change II). Discussions included time complexities, data structures (e.g., unordered_map), OOPs concepts, method overloading, call by value/reference, and pointers.

Questions Logged:

Finding Second Maximum element in an unsorted array (single traversal, handling duplicates)
Finding Majority element in an array (LeetCode problem)

• ManagerialMore Managerial questions

Managerial interview with a senior NI employee (16 years of experience). Discussed personal interests, coding journey, college experiences, project details, and general HR questions like reasons for hiring and joining NI.

Questions Logged:

Coding journey from scratch to present
Project details and challenges faced
Why should I hire you?
Why do you want to join NI?
