The technical phone screen was conducted by an engineer. He asked me two questions: 1. Find the kth largest element in an array (LeetCode 215). 2. Lowest Common Ancestor of a Binary Tree (LeetCode 236). Both questions had follow-up questions and variations: *...
I had a phone screen that included two coding questions that I hadn't seen before. - The first question involved calculating the sum of elements between two indices in an array using the prefix sum approach. - The second question required me to design a class...
I was asked to implement the following: 1. Given a custom alphabet order (e.g., `alphbet = a, d, c, b....`), determine if an array of strings is sorted according to this custom order. 2. As a follow-up, given an array of sorted strings (according to some unkno...
I'm sharing my onsite interview experience. **ML System Design:** I received a common question: nearby location recommendation for potentially moving mobile phone users. Another question I hadn't seen before was notification recommendation ranking. These notif...
I interviewed with a female interviewer who had been at Meta for many years. After introductions, I was asked about my current projects. The behavioral questions focused on resolving conflicts within my team, conflicts with other teams, and leading cross-funct...
I recently interviewed for an E6 INFRA role at Meta. I felt positive about all the interviews, but I was ultimately rejected after the hiring committee round with no specific feedback, which was frustrating. In the phone screen, I solved the problems quickly....
For the 1st coding question, it's similar to leetcode 117 For the 2nd coding question, it's similar to leetcode 1249 and the follow-ups. The follow-up question was that the parentheses were not limited to '()', but also included '[]', '{}', etc. The requiremen...
I had an onsite interview. Here's how it went: **Round 1: Behavioral** I was asked standard behavioral questions common at the company. **Round 2: Coding** * Part 1: I was given a one-dimensional array containing only 0s and 1s. I needed to write a method to q...
This was a coding interview focused on friend recommendations, using Python. The interviewer guided the session, asking about Big O notation and requiring a dry run of my code. **Question 1:** I needed to fix a `valid_recommend` function to pass a test case. I...
