Hi Friends

I m Supriyo Mondal, a final year student of Applied Electronics & Instrumentation Engineering from Haldia Institute of Technology, Westbengal has been selected in renowned softwere company, CMC, a tata enterprise on 10 th March 2007.  

The selection procedure contains :
1. Technical test
2. Aptitude test
3. Technical interview
4. HR interview

The question paper (Only Apti paper, not the technical one) was very common & same as the previous papers of CMC

TOTAL 7 sections, 91 questions, total time 50 mins, this portion was quite easier than technical
20 analogys-1 comprehension-4 questions, 20 comparisions, 20 arthematic question - easy - time is 10min, analyical reasioning 9, logical reasioning 9, data sufficiency 7, all are easy but time consuming,

All sections have different time limitation cant access d previous section while d time  allocated for another section

MICROPROCESSOR (pin number, functions, 8080, 8085, 8086, intrefacing),
ANALOG & DIGITAL ELECTRONICS (circuits &  flip flops),
C (o/p of programs & some simple basic questions),
NETWORKING (approx 13 qus, TCP/IP, OSI, data transmission),
COMMUNICATION THEORY (modulation,antenna),
MATHEMATICS (matrix, determinant) etc
Time 30 mins, each ques carries 1 marks & 0.5 negative marks, (there r no negative marks for aptitude section)

Total 67 students from EIE, CSE, IT, MCA, EE, EIE, ECE DEPT - Only 16 were qualified in the  technical & apti test. CMC's Technical test is quite harder to crack than other software companies, cause it contains ques frm various departmental & also non departmental subjects, if u r not bounded by only dept subjects then u can crack it easily


1.  Alarm:trigger::trap:spring
2.  scales:justice::torch:liberty
3.  witch:coven::actor:troupe

1.  The number is two digit number-- a.  by adding we get 5,b.  by subtractin we get 2
       ans: both a, b required

2.  Given a quadrilateralABCD determine whweter it is rectangle
      a. AB=CD
      b. angle B=90dergees
      ans:both required




1.   2m+n=10, n=5what is m
2.   if x,y positives and x/y<1 then
he has given some questions.. u can do it .. but come from last question.. not from the first one's.. they r very tough and r nothing but profit and loss, and averge, pecentge and so on.. In analytical reasoning Two passages r given in that I can provide only one

Analytic Ability of GRE BARRONS BOOK Of 13th editon..

Logical reasoning

#. 10 power 11, 10power 10 and 10 power 10
#. He has given a straight line with points x z y on that such that compare xz and xy here we will think that xy is greater

#He has given a triangle such that AB=BC=CA and he has drawn a straight line from A asuch that the line be AD now we have to compare BD and CD here we have say information is not sufficient since  here he didn't give any information  regarding that line.. so we cant say whether it dives the segment BC into two equal halves  
#1/2*2/3*3/4*4/5 +2/3+3/4+4/5 This type of questions

#Some squareroot problems he has given can't remember here the questions r very easy but see that they should be answered very carefully.. I think u got this..he hs given 20 questions ans u have to  answer it in 5min # given circimference of a circle is 4pie and for other circle ihe has given the diameter.he asked to compare  the radius of both circles..

Test Consists of two sections.

Section-1 (non-Technical)
Number of Questions : 91

Part-1: 20 verbal questions
E.g. Waterfall: Cascade:

Part-2: a passage has given and 4 questions.

When it rains or snows, service on A, 2 and 3 are delayed both in the morning and afternoon When temp. falls below 30 degrees Fahrenheit afternoon service is cancelled in either the A line or the 3 line, but not both. When the temperature rises over 90 degrees Fahrenheit, the afternoon service is cancelled in either the line C or the 3 line but not both
