The interview focused on practical coding problem-solving and communication skills, not rote memorization. I was expected to know common data structures like arrays, lists, queues, maps, trees, and graphs, and when to use them, but not to implement complex dat...

The interviewer was friendly. The coding question was LeetCode 1472. **Follow-up question I**: I was asked to implement the `haveVisited()` function to check if a node had been visited. **Follow-up question II**: handle multi-tab scenarios.
### Round 1: Coding The coding question was to write a class that supports `insert(num: int)` and `findLargest(k:int)` methods. For example: ``` insert(3) insert(3) insert(2) findLargest(0) is 3 findLargest(1) is 3 findLargest(2) is 2 ``` The goal was to make...
This was my first time participating in an onsite interview, and I was quite nervous. The entire process was smooth. A recruiter helped schedule the interview, arranged transportation (plane tickets, hotel, or local commute), and explained the day's agenda. Bo...
This was a technical phone screen for a Product Data Scientist role. However, the interviewer was from the AI team, so the questions might not have been typical. I was asked: * SQL: Calculate cohort-based retention rate (classic problem). * Python: Given a set...
After a brief introduction of the business context, I was asked a series of fundamental ML/DL questions: * The differences between Layer Normalization and Batch Normalization. * Characteristics of different regularization terms. * Approaches to CTR prediction....
I had three rounds of interviews, each lasting 45 minutes and covering coding and behavioral questions. I was expected to write main methods to run my code and provide complete solutions for all follow-up questions. For behavioral questions, I was asked about...
The interviewer was the hiring manager. I had to implement K-Means clustering, but it didn't need to be runnable. The interviewer just needed to see that my implementation was okay. I could use any framework I wanted (Python/NumPy/PyTorch).
Round 1 consisted of a medium-difficulty problem from the Leetcode 150, followed by a behavioral question: How do you make decisions if you have multiple solutions? In Round 2, I was asked about debugging, error handling, and how to approach pull request refac...
I interviewed with Mustafa's organization after a recruiter contacted me on LinkedIn. The interview consisted of six rounds. The first two rounds were coding, followed by two system design rounds. The fifth round involved a deep dive into my past projects. The...
