Be sure in answering these questions as it plays a major role in Personal interview. HR will have a copy of this answers you have provided and questions will be asked from this. If you fail to answer in a proper way, then HR will consider you as a person of flexible answers. A total of 40 questions will be asked and time allotted is around 15 minutes. If any paper is provided, note these questions in it for your own goodness.

Round 4. GROUP DISCUSSION :

Group discussion round held in MRF is bit different when compared to other companies. Topics were not be asked in MRF. Usually a problem will be provided and discussion has to be done regarding the topic being provided. It is easier in one way but on the other side, you feel that there is nothing to talk. At such situation, try to deviate the topic, this is highly focussed in MRF recruitment. The problem provided to us is named as                                              
                                "SWEET PROBLEM"


                   On Sunday early morning Ramakrishna goes to a sweet shop and asks the shopkeeper the cost of 1 kg of sweet. The sweet shopkeeper replies " 1 kg costs  Rs. 24. Ramakrishna purchases half a kg. of sweet and gives the sweet shopkeeper Rs. 20. The shopkeeper does not have change as it was early in morning and he moves to a tea stall owner to get change. He gets change for Rs. 20 and gives Rs. 8 back to Ramakrishna. 

             During day time, the tea stall owner rushes to sweet shopkeeper and tells him that the money he has given is counterfeit and asks him to give Rs. 20 back. The shopkeeper now gives him his Rs. 20

               Find out the total loss incurred to the Sweet shopkeeper without including the cost of sweet.

TIPS for attending GD:


Maintain good communication and be bold and fixed to your point. Whatever the point may be, be sticked to your point till the end of GD. Never try to use even a single other language word. This happened to a boy in my GD session. His English was good but he used a single word in Tamil while concluding ( "Avalathan"). HR pointed it out and asked him to repeat that word and thereby he was trapped. 


Round 5 : TASK SCHEDULING 

In this particular session, various tasks will be given and it will be asked to make an arrangement as per the time allotted for each operation.

The task given to us is :

You are working in this industry for more than 8 years. At 8:50 am you get a message that a worker is being injured and has to be replaced with another for operations to be processed. And also by 4:00 pm you must attend a birthday party of your colleague.
You receive a call from your mother that you must take her to hospital at 2:00 pm and thereby get a permission from your higher officials. At 9:00 am you have to attend a meeting with your senior officers regarding the statistics of Sales. 

It is also found at 10.15 am that the amount of raw materials is being out of stock and as to be reported for further operations of production. The stock has to reach the industry by 11:00 am. 
A person at the shop floor gets a permission for half a day, he has to be replaced with another person for continuity of operation.

Make a proper time format of these operations. Assume that the time now is 9:00 am. 


After the completion of this round, the names are being shortlisted and they will be asked to attend two more rounds which is Technical interview & Personal interview.

In United Arab Emirates (UAE), a huge proportion of electrical energy consumed in buildings is used to run  air  conditioning  equipments.  This  is  because  UAE’s  climate  is  characterized  by  very high  ambient temperatures and high humidity, especially during summer periods. There is need to promote air conditioning  systems  that  are  run  by  renewable  energy  based  power  because  of  the  environment  threats  and  energy  security  negative  issues  associated  with  conventional  fossil  fuel  –  energy  powered  systems.  


48. PRELIMINARY MISSION ANALYSIS AND DESIGN FOR A SMALL SATELLITE SWARM


The thesis is a preliminary mission analysis and design of a small satellite swarm. The concept of the mission is to probe altitudes between 200 km and 6000 km to study the structures and dynamics of the magnetic field aligned currents. The mission lifetime is about 3 months. Aerodynamic drag at low altitudes is used for orbit and formation control.


49. RAPID POLYMER PROTOTYPING FOR LOW COST AND ROBUST MICRO ROBOTS


The Rapid Microrobot Prototyping (RaMP) Process uses Loctite R photopatternable polymer products and photolithography to rapidly fabricate robust, inexpensive, and compliant robots. The process is developed and examined on two size scales.








50. REMAINING LIFE ASSESSMENT (RLA) PROCESS OF ELECTRONIC SYSTEMS


The remaining life assessment (RLA) process is a reliability prediction process, which predicts amount of life left in a system. Remaining life assessment is performed on hardware, which has already seen operational life. This thesis details the remaining life assessment process in detail and also provides a case study of remaining life assessment performed on the Shuttle Remote Manipulator System (SRMS).

51. REPLACEMENT OF AN ELECTRICAL HEATING SYSTEM

The first part of this thesis contains the energy balance for the different kinds of flats to 
see how much energy they consume for heating and hot tap water. To get theses values 
we  have  to  analyse  the  total  energy  flow  into  one  flat  and  compare  it  with  the  energy 
which is used because of transmission losses, ventilation losses, hot tap water, electricity 
for the household and natural ventilation and infiltration.

53. SIMULATION AND CONTROL SYSTEM OF RAILROAD TRACK

With  the  vastness  of  existing  railroad  infrastructure,  there  exist  numerous  road crossings  which  are  lacking  warning  light  systems  and/or  crossing  gates  due  to  their remoteness  from  existing  electrical  infrastructure. Along  with  lacking  warning  light systems, these areas also tend to lack distributed  sensor networks used for railroad track health monitoring applications.

54. SIMULATION AND MODAL ANALYSIS OF INSTABILITY AND TRANSITION IN A STEADY ECCENTRIC STENOTIC FLOW

Direct numerical simulation (DNS) of steady ow, with Re = 750 at inlet,through stenosed pipe has been done to study transition and turbulence of theow in the post-stenosis area. The pipe has 75% constriction by area reduction and 5% eccentricity of the main pipe diameter at the throat. A sinusoidal Gaussian force is implemented to keep turbulent in the domain. 



55. SIMULATION OF THERMAL STRESSES IN A DISC BRAKE

The heat flux produced from the friction between a disc and pad system leads to a high temperature which causes thermal stresses in the disc and after a number of repeated  braking  cycles,  cracks  might  be  initiated.  The  finite  element  analysis (FEA)  is  performed  to  determine  the  temperatures  profile  in  the disc and  to analyze the stresses for the repeated braking, which  could be  used  to calculate the 
fatigue life of a disc.


56. SIMULATIONS OF SOUND PROPAGATION AT A DUCT TERMINATION WITH FLOW

Both theoretically as well as in many applications like exhaust systems, ventilation pipes, mufflers, air intakes and also large scale industrial smoke stacks, it is of interest to understand how sound waves are scattered at duct exists.Especially for aeronautical application such as jet engines, the effect of coupling of acoustics and flow on sound radiation and reflection from a duct termination in a uniform is an important problem.


57. SPRAY AND WALL FILM MODELING WITH CONJUGATE HEAT TRANSFER IN OPEN FOAM

Scania is today a manufacturer of heavy trucks, buses and diesel engines with an annual turnover of approximately 88 billion SEK and a total of 35000 employees in 100diff erent countries. Approximately 3000 of these work with research and development in Sodertalje. Scania's diesel engines are developed mainly for their own trucks and buses but also for other heavy duty vehicles, marine applications, industrial applications and power generation.



58. STRUCTURAL ANALYSIS OF A WASHING MACHINE THROUGH ITS LOADING CASES

Washing machines are commonly used in almost every home worldwide. These appliances make it easy to clean clothing; a process that time ago was heavy and unpleasant. The performance of these machines  is  based on the  rotation  of the clothes  inside  a  cylinder  while  they  are  mixed  with  water  and  some  kind  of cleaning powder or soap.

59. STUDY OF TEMPERATURE RAISE IN GAVLEÅN RIVER RELATED TO DISTRICT COOLING

This project is a preliminary study in order to build a small power plant, located beside to Gavleån River. It has been designed with the aim of cooling a district of Gävle city,Sweden. That big project is carried out by the international consulting engineering company SWECO.

60. TECHNOLOGY DEVELOPMENT IN THE SOLAR ABSORPTION AIR-CONDITIONING SYSTEMS

An environmental control system utilizing solar energy would generally be more coste€ective if it were used to provide both heating and cooling requirements in the building itserves. Various solar powered heating systems have been tested extensively, but solar powered air-conditioners have received little more than short-term demonstration attention.This paper reviews past e€orts in the ®eld of solar powered air-conditioning systems with the absorption pair of lithium bromide and water.
