Interview Preparation Tips

Round: Test
Experience: Round one
was an online technical and general aptitude and English round.
There were two sections.
First you have to complete general aptitude questions in a fix time (45 or 30 mins).
Questions in this round were very easy and basic and related to time and work,
train problems, age problems, percentage, number series questions, English and
logical reasoning questions.
In second
section there were two coding questions. You have to code them in 30 minutes.
Questions were very easy like Fibbonacci series, Matrix Multiplication,
Factorial, Vowels and consonants separating, power finding, Numbers and character
separating etc.
Tips: Attempt Both the coding question if it is possible.

Round: Technical Interview
Experience: It was an online coding round. They sent two questions for coding and then email the code to them. Questions were very easy. you have to code them in one and half hour.
Everyone coded both of the questions. (sorry I forgot the questions).

Round: Technical Interview
Experience: It was a
little tedious round. They asked concepts related to networking like IPv4,
routing, Subnet masking, Internet Layers, Network Modules. They were trying to
cover all topics. Then they ask related to software computing and their modules, Database modules and some SQL queries. There were questions related to data structures like arrays, link
lists, searching techniques and their complexities, some C and C++ concepts.
It was approximate two hours interview. You have to clear all the basics concepts of
all the subjects for clear the interview.

  • Ans. 

    Probability of a horse going out of a chessboard in 'n' steps.

    • The total number of possible moves for a horse is 8.

    • The probability of going out of the board depends on the position of the horse.

    • For example, if the horse is at a corner, the probability of going out of the board is higher.

Interview Preparation Tips

Round: Test
Experience: They did not expect any code in this round. An algo or pseudo code is fine.



1) You are given 2 vessels with capacity M liters and N liters capacity and infinite supply of water. You need to find the minimum number of steps required to get P liters. Any of the below action is considered a step



     a) Filling vessel with water



     b) Emptying vessel



     c) Pouring water from one vessel to another vessel.



2) Given n sets each containing m integers. You need to create MinDiff set by picking exactly 1 element from each set. The difference between the maximum and minimum elements in the MinDiff set should be minimum.



eg: for the sets {30, 20, 10, 40},{ 22, 33, 44, 99},{ 16, 17, 18, 19} min diff set is {19, 20, 22}. Max and min elements in MinDiff set are 22 and 19 and their difference is 3.

Round: Technical Interview
Experience: 1) you will be given the binary representation of the numbers in the form of 2D array.eg: r1- 00001

r2- 00100

r3- 01010

r4- 00110

r5- 00111 This means the elements are 1, 4, 10 , 6 and 7.

A number “n” is given. Let us say that n can be formed by doing bitwise OR operation on rows of given matrix. What is the minimum number of rows that needs to be deleted from the matrix so that “n” can never be formed by doing the OR of the rows.

If n is 14(01110) then it can be formed by doing r2|r3 or r3|r4. You can prevent n formation either by deleting {r2,r4} or {r3}. But {r3} has least number of elements so it is the required set.2) Find the average of mid 50% of elements in the running stream of integersI have not cleared round-II so no further questions.

Interview Preparation Tips

Round: Resume Shortlist
Experience: The first round was a resume shortlist, which I think was on the basis of programming and coding courses (and projects) taken along with your CGPA. Out of 10 shortlisted people, I knew 4 and all of us were 9 pointers. The rest who I didn't know turned out to be 9 pointers as well! :P
Out of 10 shortlisted people, 3 (including me) were from ECE and the rest were from CS. Even though InMobi was open for Mathematics & Computing, no person from MnC dept. was in the shortlist. (Presumably due to their CGPAs or some other criterion that I'm not in the knowledge of.)
Tips: i) High CGPA is a must (We're talking above 9, at the end of 2nd year for CS/ECE and 3rd year for MnC)
ii)Taking programming and algorithm courses and projects is important, as that must be visible in your resume.

Round: Puzzle Interview
Experience: One special thing about the interviews, you're asked not to wear any formals! That actually helps in taking the tension off of things!
It's simple logic, after that. Increase the lift's speed (taking in mind of the safety), collecting usage data, optimising the lift's floor-stoppage according to that.
As told after the interview, the interviewer is just observing how you think and approach a problem.

One odd thing was not being asked about any coding/algorithm questions even though the profile was for a software engineer.

After this question, I was asked if I had any questions to ask. I simply stated that the work environment and culture affected me as much as the profile I'm applying for. Thus, the drive and motivation of the people who work there is also very important. So I asked what are the companies' values which the employees believe in, too.
Tips: Stay confident, don't let any tension get to your head.
In the future, InMobi may start asking coding questions too in the interviews. or change the selection procedure, which will be communicated in the PPT of InMobi.
Whatever may happen, the first round should show your zeal to solve problems, your creativity in trying different approaches, and applying logic to find the best solution.

Round: HR Interview
Experience: OK! There were a lot of questions asked since the interview was more like a conversation taking place. Like in ANY conversation, keep proper eye contact, smile and be approachable for any questions. Show enthusiasm in your voice and your answers. The interviewer asked me questions about
i)My resume, and all the activities that I'd listed there. (eg: Why did you enlist in this course? Do you like coding?)
ii)Why programming, how does it interest you?
iii)Basic questions about InMobi, like 'What do you know about us after attending the PPT?' and 'Why InMobi'

Since I had done quite a lot of marketing activities, I was also asked about that. Will you do an MBA in the future? What all did you do for marketing? I had a strong background in digital marketing, and we had a little chat about mobile marketing and what's the future of mobile advertising.
Tips: Smile, for god's sake! It's a conversation about you, do all the basic things to improve the conversational experience.
Small things like greeting the interviewer, smiling, proper eye contact, and speaking properly are paramount.

Like in any HR interview, make sure you know yourself and your resume properly, so that you don't phase out in the interview when asked some 'unexpected' question. (since that's when they know thatyou might be lying/exaggerating). Hence introspect enough before sitting the interviews.

General Tips: Make sure you're able to convince yourself and the interviewers for why do you want to work in Inmobi Technolgies.

I've already shared the rest in previous sections! :)

2 people out of 10 were selected for this internship experience, so make sure you prepare well! All the best! :D

Skill Tips: I don't think that this adds on as a skill, but InMobi wants to create a huge impact on the mobile world and the mobile advertising sector.
Your knowledge about this sector in general could help you strike good conversations (at least in the HR round).
Skills: Logic, Problem Solving Abilties, Creativity, Communication Skills
Duration: 2.5
College Name: IIT Kharagpur
Motivation: I'm a gadget geek from my childhood. The mobile industry amazes me as it's been the biggest change-bringer in the modern world. InMobi as a company wants to create a huge impact in the mobile advertising space and mobile advertising! And seeing their products that they offer in this domain had me thinking that they're doing something unique and awesome!
The work culture of InMobi is just amazing, right from flexible work hours to the epic office they have in Bangalore full of awesome people working towards that one goal! Also, InMobi offers their employees opportunities to shift between various verticals if they want to. All of this (along with a good compensation ;-) ) was enough motivation for me to apply!
Funny Moments: When I was asked whether I was in the third year, I said yes, and then said, usually people think that I'm still in high school!
We had a good laugh on that one! :P

Otherwise also, the entire procedure was relaxed and fun in general.
