Motorola India Placement Paper at Trivandrum

 

Motorola India came for campus placement at Trivandrum College

 

I am providing the sample test paper and selection procedure for Motorola India Pvt. Ltd. (GSG - Global Software Group)test held at College of Engineering campus.

 

1. Pre ? Placement Talk

They give a ppt or paper presentation during which one can know about the company. You have to listen to it carefully as they sometimes ask questions about the things they tell you in ppt.

 

2. Motorola Test Question paper

The test was very short. There were 30 questions to be done in 30 minutes. There were separate sets of questions for Electronics ece and Computer Science cse streams.

For computer science students, the questions were from the important degree subjects like OS, Data Structures, C/C++, Networking, Aptitude (Logical and Quantitative). There was no negative marking in the motorola exam.

 

3. Motorola Technical Interview

After the exam, there was a detailed technical and personal interview. They took a lot of time for every candidate. Asked all types of technical questions and test all your tech skills. What you write in your resume, it matters a lot and they ask questions according to that. You can also be asked about your projects and related questions.

 

4. Motorola HR Interview

The HR interview was somewhat tough. Some persons could find it hard to answer the questions. But dont worry and stay confident. If you have done well in the tech interview round, then you can do this one easily. good luck for that.. those who passed the interviews were given offer letters. You can prepare and practice using other previous placement exams test question papers here and the technical section problems of other companies tests.

Type : Fresher, Job Interview

 

Motorola india -job profile was writing codes/programs for its mobile,job location banglore. test paper consisted of 30 objective questions. most of them were electronics,3 c programs-find out mistakes from them.In one of them an int type variable was assigned value using function: int i= func(),however the function was not declared earlier.

 

One question was on enum declaration enum a ( a=1,b,c=2,d; ) what is value of b? Binary tree was given and its output when printed in inorder,post order pre order The chapter miscellaneous features oc c in let us c by yashwant kanetkar proved to be useful electronics questions- One question was to find swr. fourier transform of contionuous periodic ,contionuous aperiodic,discreet periodic periodic discrete aperiodic signal is-(match the following type of question) Which of the following type of AM requires least power ssb veatigial side band dsb suppressed carrier iir filter is an all pole all zero no poles poles and zeros Question based on the x(k) =x(N-k) property of dft. Who is the global brand ambassador of motorola?

 

Interview Questions-Tell us about yourself. Describe and give functions of layers in internet-application,transport etc .what happens in cyclic redundancy chek.than he asked do you know sliding window protocol .(ans-no) what is AM,FM,CDMA.(when i told that codes are orthogonal in CDMA than he asked what is orthogonality)why do AM waves propogate farther than fm.what happens in GSM(i.e fdma or tdma) Few people were questioned on dsp,c programs or/and there projects. told to implement a boolean equation using nand gates. then questions on C Language.
