Teradata recently visited the candidate's campus for developer and test developer profiles, and the candidate was shortlisted for the developer profile.

Round 1: Written Test
This round consisted of 20 MCQs with a time limit of 40 minutes. Questions covered Data Structures, Operating Systems, Computer Organisation, and Recursion. The difficulty level was described as medium to hard, requiring strong conceptual clarity. Only 4 candidates were shortlisted for the second round.

Round 2: Technical Round (2 hours)
This round was comprehensive and included several coding and design problems.

• Coding Question 1: Given two sorted strings of length m+n and n, merge them into a single sorted string of length m+n in place.
• Coding Question 2: Run length encoding, with a focus on handling the worst case where each character is repeated only once.
• Coding Question 3: Mirror of a binary tree.
• Design Question 1: Design a stack data structure that allows push(key), pop(), and max() operations in O(1) time, with efficient space usage.
• Coding Question 4: Search in a row and column sorted matrix.
• Coding Question 5: Root to leaf path equal to a given sum.
• Coding Question 6: Given an array, find if an element can be represented as a subset sum of the array.
• Technical Question: Declaration of some complex function pointers.

Round 3: HR + Technical Round (1 hour)
This round combined technical and behavioral aspects.

• Coding Question: Write code that returns true if a matrix is a subset of another matrix.
• Behavioral Questions:
• Introduce yourself.
• How did you overcome some serious problem of yours?
• Why did you work as an intern for a company that paid you nothing?
