Tech Mahindra Placement Paper on 8th Jan 2010 at Nagpur
Campus Recruitment By Tech Mahindra At Priyadarshini college of Engineering, Nagpur On
8th January, 2010.
Hi friends, I am sharing my experience with Tech Mahindra with you. I am Sanket, final
yr. IT student of Priyadarshini Institute of Engg. & Tech.,Nagpur, 2010 batch. I got placed at
Tech Mahindra with the blessings of God, My family & well wishers. And yes
Discussionsworld helped me a lot...
q's from quantitative apps
Q's from reading comprehension
Q's Englsh-1
Q's English-2
It was a 3 stage procedure
1.Online Aptitude Test
2.Technical Interview
3. GD + HR
They gave nice presentation & explained the procedure for online apti.They will give unique
username & password to you to access the online test paper.Different paper sets are there,
so don't peep into neighbor's PC.
1. Aptitude Test
Apti had 100 questions to be solved in 60 mins. Questions were divided into 6 sections
1. Verbal reasoning
2. Non-verbal reasoning
3 Quantitative Aptitude
4 English I
5 English II
6 English III
There was sectional cut-off. They told us there was no negative marking. But after results
were out for Apti, many of the students who solved whole paper could not cleared the Apti.
No. of candidates clearing the apti was less, so there must be a negative marking.
Solve English Section first, they were so easy. Synonyms, antonyms, reading
comprehension, filling blanks with proper verbs, adjectives, prepositions, etc. Above average
student can also solve it in 15-20 mins. No need to go through Barrons.
Verbal reasoning & non-verbal reasoning were easy. R.S. Aggarwal is more than enough.
Go through it. Practice all type of questions from it. Different sets had different problems. so
don't left any part of R.S A.
Quantitative part had 12 questions. Some were very easy, some were easy but lengthy, 1-2
were really tough. Try to give them at least 15-20 mins.
Results were out in 20 mins. My friends told me i cleared the apti. Since i had little doubt
abt my Quantitative & sectional cut-off was there, i didn't believe them. But then I heard my
name, WOW, What a moment!!! a cleared most difficult hurdle of my way. Though TechM
apti was easy but sectional cut-off(& probable negative marking) makes it difficult Only 10-
25% can clear such an EASY Aptitude Test.
Then they give a form to fill to us. They asked for general information such as Educational
details, passport details, family details,languages known, career objective for next 3 years
(be specific such as system analyst, software testing, etc.)Future educational plans(eg, M.
Tech. DON'T WRITE MBA IN HRM particular, You may jeopardize your selection in HR Round)

T.I.: Plans about Further studies??
Me : (Told exactly what I had written on their form). M. Tech but after 4 years.
T.I: Ok Sanket, You may go now.
Me: Thank you sir.
It lasted for abt 20 mins
I was really disappointed with my interview. I knew the answers of the questions
but didn't remembered those & I was angry on myself, shouting , yelling & really scared that
i wuold not get through the TI. I wanted to answer all the questions & those 2 "DON'T
KNOW"s were really hard to me to digest. I was waiting for TI result keeping my fingers
crossed.
I was confident, loud & clear while answering his questions. Even I said Don't Know
Loud & clear. Always gave answers after taking a small pause. Kept eye contact with him &
shows eagerness in my eyes while listening to him.
That worked for me.
Some guys were asked for their favrt subject & que based on it., abt project,
DBMS, ckts(ET students).Some guys were asked for only 1-2 technical questions, rest were
all HR questions.
It was TI + HR in fact.
Results were declared at around 9 pm.
I was overjoyed. I knew now I can easily clear GD+HR round. I was confident
about my selection. They gave us declaration form to fill & told to be ready with self-
attested documents (college ID+ previous mark-sheets, 10, 10+2 mark-sheets photocopies)
At 10pm, they announced that further round would be held on tomorrow. we
returned.
Next morning, HR took GD+HR.
He told some groups to choose the topics themselves, to some he gave the topic.
In my case, he gave us topic "whether marriage is necessary in Indian society."
Total 6 were there in my group
He grouped us & placed me in Against marriage.
It was easy for me & I was confident about my selection. One guy had written MBA
in HRM as his future career. HR shouted at him," If you want to be HR, why are you here.
Go & do your MBA. We want Technical People" That guy gave him some lame reason. So,
Don't try to fool HR, he is smart & know more thank you.
Do speak something in GD, you will get selected. HR didn't ask me anything, but he asked
some candidates about some significant people of India, Mogul Empire, hobbies, abt
attitude, latest issues, etc.
Other topics in GD were Separation of states, Capital Punishment to Kasab, Divorce
laws, such current issues.
Final Results were declared after an 1:30 hrs. My name was there. Package was 2.9lpa
That was the greatest moment of happiness of my life. I've got a job!!!! Only 3
from my branch were selected including me. One was my best friend. Total 18 were finally
placed from about 135 students of my college who sat for apti.
Very few candidates were rejected during TI & then during HR. Almost 90% guys
who cracked the Apti got placed.
Remember, if you cleared the Apti, rest will be much easier to you. For TechM, go through
R.S. Aggarwal thoroughly.It's sufficient. Remember Time Limit.Solve all the sections. At
least 60% questions from each section first to clear sectional cut-off & then try to attempt
others. Complete English Sections first, they are easy. In skill set, write about only those
languages where u are really confident & perfect. Better you write only C & prepare
thoroughly & clear all the concepts abt C. Refer Let Us C by Kanetkar for C. Be ready to
answer about your project, many question are based on your resume & form you fill before
entering TI. So think before writing something there.
I thank Discussionsworld, it was immensely helpful to me. It was my first online apti,TI &
GD, & I got placed. I got idea for Tech Mahindra preps from Discussionsworld & things
became easy for me. Pattern was similar to that discussed
here.
BEST OF LUCK!!!
