TCS Test Pattern
The selection procedure of TCS consists of following 3 rounds
1. Written Test
2. Technical Interview
3. HR Interview
1. In written Test:
No of questions: 35
Time limit: 80 Minutes
Negative mark: 1/3
Calculators can be allowed
For each wrong question 0.33 marks will be deducted.
Just practice the previous questions
Lots of unnecessary data (read carefully)
Take care of negative marking and attempt a question only if you are sure.
Take your time for each question and move on if you don’t know any.
Areas to concentrate
Time and Work
Coding and decoding
Permutation and combination
Clocks and calendars
Practice more reasoning questions
C++, java, OS, DBMS
1. Alok and Bhanu play the following min-max game. Given the expression N = 19 + X * (Y - Z), where X, Y and Z are variables representing single digits (0 to 9), Alok would like to maximize N while Bhanu would like to minimize it. Towards this end, Alok chooses a single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally Alok proposes the value for the remaining variable. Assuming both play to their optimal strategies, the value of N at the end of the game would be
2. The number of bacteria in a colony was growing exponentially. At 4 pm yesterday the number of bacteria was 400 and at 6 pm yesterday it was 3600. How many bacteria were there in the colony at 7 pm yesterday?
3. A multiple choice question has 4 options. Choosing the correct option earns the student 3 marks. However choosing the wrong option incurs negative marks so that if a student chooses an option randomly, his expected score is 0. Suppose a student has successfully...
