Entrevista
Technical interview involving solving 1 problem of finding the missing number in a sorted list, after considering a brute force solution the interviewer prompted me to come up with a faster solution with binary search. He was helping along the way and very nice. Then moved on to some tracing problem in C++, pointers related. In the end, he gave an overview of my performance which is very helpful!

It was average. They asked me to code 2 questions and perform a more efficient approach for both. However, for some reason, they rejected me 30 mins after the interview was done.

Entrevista
1. Data Structures (Tree Traversals)
Asked to explain and write the algorithms for Inorder, Preorder, and Postorder traversal of a binary tree.
Follow-up: difference between DFS and BFS traversals.
2. C/C++ Programming Concepts
Questions around:
Memory & Pointers → how pointers work, pointer arithmetic, dangling pointers.
Pass by value vs pass by reference in C/C++.
A question on JWT (JSON Web Token) – concept, usage in authentication, and security aspects.
3. Tree Coding Question
Problem: Check if a target value exists along any root-to-leaf path.
Required to construct the full binary tree and then write the function for path-sum/target check.
Expected to implement full code (not just pseudo code).
4. Bit Manipulation Problem
A logic-based coding problem using bitwise operators.
Example (not exact wording): Given a number, perform certain bit manipulations (like checking set bits, or toggling).
5. Next Greater Element (Variation)
Classic stack-based problem: find the next greater element for each element in an array.
Variation was asked (could be circular array or next greater frequency element).
Needed optimized solution (O(n) with stack).
Preguntas de entrevista [1]
Pregunta 1
Questions on pointers and memory (pointer arithmetic, dangling pointers).
Difference between pass by value and pass by reference, with code examples.
Some discussion around dynamic memory allocation and how it’s managed in C++.
Emphasis on understanding how things work at a low-level in memory, not just syntax.
The interview consists of one round, which includes solving a Leetcode Medium-level coding problem and a comprehensive review of your resume, covering projects, experience, and technical skills in detail. Full time roles can have more interviews
