I was interviewed on-campus
Mahindra & Mahindra
Test Group Discussion Technical Interview
No. of Questions
- Section 1: Numerical Ability
- Section 2: Analytical Ability
- Section 3: English Proficiency
- Section 4: Technical
APTITUDE:They covered almost all important topics in Numerical Ability like Profit&Loss,Simple Interest,Compound Interest,Time&Work,Speed&Distance,Percentages,Progressions,Probability.In Analytical Ability questions are on Sequences,Decoding,Reasoning,Relationship Problems,Data interpretations.In verbal questions are on comprehensions, Correct the sentences,direct & indirect speech.My advice is to answer verbal section from the end.
TECHNICAL: 50 Questions->Fluid Mechanics & Hydraulic Machines: A total of ten questions are asked on this topic.Concentrate mainly on Centrifugal pump(NPSH,Cavitation,Parts),Turbines(types of pumps, where they will used and why).->Strength of Materials:Simple problems on torsion,bending,buckling,impact loading(understand the all formula physically),some questions on I & J calculations. ->Thermodynamics(three Laws) and Heat cycles:You need to know all cycles like Otto,Diesel,Stirling,Carnot,etc.,compare their efficiency).->Design:Problems(Bolts,rivets),Couplings, Bearings.->Production: Materials(% of carbon in various kinds of steel, Alloys),Tool Signature and physical meaning, Thermal aspects of tool design.In all the above topics simple problems(Basic formula based) are asked but time is not sufficient, so good practice is needed.
All these questions are of moderate level.If you find initial questions are tough then start answering from the end,this will really help.Time management is very important
Group Discussion Topic
Its a Case study on Environment Protection.
Case study topic: A plastic industry is releasing poisonous waste into near by lake. A new technology is introduced into market which will reduce the amount of waste. but this technology is expensive. At present waste released into the lake is as per the norms of government. But if they release waste at the same rate after few years, water in this lake will not be fit for any use. Budget of the environmental section of the industry is running out of funds.We are asked to create a mind map to take decision on buying this new technology considering all the above constraints.I initiated the discussion which helped me a lot. I add points on taking help from Government, NGOs, Collaboration with other companies to get this new technology.
Following criteria is generally followed by all companies in evaluation:1)Initiation2)Clarity of speech3)Open mindedness4)Value added to the discussion5)Body Language6)Conclusion7)Behavior after group discussion
- Question 1: Tell Me about yourself.
