Inmobi’s hiring process for roles outside the core SDE track (e.g., recruiting coordinators, deployment engineers) varies significantly in focus. Technical roles emphasize deployment, orchestration, and infrastructure, while non-technical roles prioritize behavioral and situational assessments. The process is often less standardized, with a stronger emphasis on domain-specific knowledge.

The candidate had their interviews with Inmobi in June 2022, but after submitting all required documents, they were ghosted and did not receive any further response or update on their application status.
The candidate went through three technical rounds at Inmobi, covering data structures, algorithms, probability, and multithreading. The difficulty was moderate to high, and the candidate provided detailed solutions for each problem.
Discussion about projects and solving problems related to BST and arrays.
Find two elements in BST such that their sum is k
Given an array, find minimum positive integer missing in O(n) time
Focused on programming and problem-solving, including binary search, memory overflow issues, and array manipulation.
Write a program for binary search. Discussed if any memory overflow problems occurs and how to resolve them.
Left shift an unordered array by k times in O(n) time.
Solved probability-based problem involving robot movement on a 2D grid and a multithreading problem to track subroutine calls without using synchronized keyword.
Given an island represented in a 2D array of size mxn, a robot position (x, y), and k steps, what is the probability of the robot surviving after making k steps?
Given a subroutine in a multithreaded web application, track the number of times it is called without using the synchronized keyword.
