InMobi visited our campus and conducted their interviews in December. The recruitment procedure consisted of an online screening round followed by 2 technical rounds and 1 HR round

Round 1 The online assessment consisted of three questions and the duration was 2 hours. It was held on DoSelect platform. The following questions were asked:- https://cses.fi/problemset/task/1674 (Something similar to this) https://www.geeksforgeeks.org/dsa/connect-n-ropes-minimum-cost/ (The only catch was that input was given in comma separated form so had to parse those) https://leetcode.com/problems/cheapest-flights-within-k-stops/ After the online round 25 people were shortlisted and 25 people in extended list. Interview was scheduled on 1st December and was to be conducted on MS Teams.

Round 2 The interviewer was quite friendly and gave his introduction and asked for the same. After this he asked an open-ended design question. The task was to design an hospital appointment system with certain priorities for patients. The main discussion point was choosing best data structures for the design purpose and object-oriented paradigms which needed to be followed.

Round 3 The interviewer was quite serious and started with DSA question. The first question he posted was quite complex to understand at first but after looking carefully it boiled down to finding next smaller element concept and I told him the stack solution. He was impressed and asked for a more optimised approach which uses constant space. After few hints from his end, I came up with the code. After this he pasted another question which was this https://leetcode.com/problems/maximum-number-of-visible-points/ Though I have seen this question but never solved it, so I was stuck for a few minutes but then I tried to explain a mathematical approach but was not getting it right. After a few hints, I deduced that this can be done using sliding window and some general maths. I quickly coded it up and he was satisfied and asked if I have any questions.

Round 4 This was a chill HR Round and he just asked basic introduction, life in Covid times, about my projects and hobbies. This round was done within 10 minutes and after a few minutes, I got a confirmation from TnP cell that I am selected in InMobi.
