I had a total of four coding rounds. None of the problems were directly from online problem sets. The topics covered in the interview rounds were binary trees, hash tables, heaps, and intervals. I think communication with the interviewer is more important than...
The interviewer was direct from the beginning and did not spend much time on small talk. The question was Build Target Recipe Value: https://www.chillinterview.com/learn/coding-interview-questions/build-target-recipe-value The setup involved base ingredients,...
## Preparation Tips & Key Takeaways ### What I Learned - I learned to be prepared for unconventional easy coding questions. - Practicing behavioral questions is crucial to communicate experiences clearly and concisely. - Being able to explain my thought proces...
To prepare for similar interviews: 1. **Graph Algorithms:** Thoroughly review fundamental graph algorithms, including BFS, DFS, Dijkstra's, and A*. Practice implementing these algorithms from scratch. Be prepared to analyze their time and space complexity. 2....
The interviewer introduced the scenario as a customer data cleanup task. The question was Group Customer Records by Shared Information: https://www.chillinterview.com/learn/coding-interview-questions/group-customer-records-by-shared-information. I was asked to...
### Round 1: AI/ML Technical Knowledge The interviewer focused on the AI/ML projects and experience listed on my resume, asking in-depth questions about my work. I felt this round was new to the interviewer as well, and they mentioned it was their first time c...
The coding question I received was: Find the cheapest common ancestor for two nodes in a tree. Each node of the tree has a price and knows its parent and children. You are provided with two different nodes of the tree and you must find the one with the cheapes...
I took an online assessment consisting of two questions. **Question 1:** Given an email content string, a verification string, and a slice constant k, I was asked to map every k letters in the email to a checksum number (a-z as 1-25, ":", "/", "." as 26-28), s...
## Round 1: Array and Stream Processing The coding question involved manipulating an array based on a given offset. The follow-up required adapting the solution to handle an incoming stream of data using `hasNext()` and `getNext()` methods. **My Approach:** 1....
