TCS Technical Interview Questions

To check if you have clarity & knowledge on basic Technical Concepts

and to check your analytical abilities and skill in building algorithms for

solving problems.

What are your favorite subjects?

Tell me about your project? Few questions on final year project. What isthe platform for your project?

What are Javabeans? What is a servlet? Describe portability? Is platform independence useful property in Java? What is redundancy?

What is denormalisation? What are the advantages of normalisation? How can you invoke Servlets? What is data structure? What are the various forms of data structures? What is a kernal? What are the functons of kernal?

What is a view? Difference b/w view and a table?

What is the difference between array and vector?

A question on group-by clause? What is the difference between sequential and index file system? Write aC program if str1=anil samal str2=sa str3=b if str2 is

found in str1 then replace str2 with str3?

What is Multithreading? What is Inheritance ?

Is there any concept of Multiple Inheritance ?How can we achieve MultipleInheritance ?.

Question on RDBMS.

What is DDL & DML ?

Do you know JDBC ?Pl explain

Can you write the code to connect Java with any Database ?.

Explain concept of Data Structure with Practical examples.

What is OOP .Explain, giving practical examples

Difference between C and OOPs Explain function overloading . Along with feature of OOPs inheritance,

polymorphism, abstraction and encapsulation

Difference between about Linux and windows OS .

2/6

Complete the series 26, 19, 17, 13, 11,, 8, 7 (Ans: 9).Sol: 26,17,11,8 these are decreasing like 9,6,3 19, 13, 9, 7 these aredecreasing like 6, 4,2

Logic :Build an algorithm using C on the spot to resolve a puzzle like

sudoku.

An additional frequent C interview question you can anticipate would be to

debug errors in a given plan. Once more the significance will not be on the

syntactical errors. Instead there would particular logical errors like infinite

loops or divide by zero exceptions deliberately designed in the existing

code. You will have to figure out the errors. Sometimes you may be asked

to correct the code as well.

RDBMSNormalization and its types, Types of rdbms, keysprimary

Candidate, unique foreign,. Why the term relational? What is itsmeaning

What is SDLC. Explain all the steps.

Difference between structure and union?

Please write a program for sorting?

Difference between calloc and malloc???

What are the principles of OOP? Explain them with real world examples?

What is preprocessor? Explain about storage classes? Explaincompilation process in C?

Explain about the difference between a primary key and a Unique key? What are the different RDBMS explain about one of them? What is a palindrome? State the logic behind palindrome program?

How do you sort programs or database or applications?

What is the main difference between PL/SQL and SQL?

Why do you use stored procedures and what is their main functionality in aRDBMS?

Explain about UNIX and the various command used to search for errorsduring run time?

Explain the difference between overloading and overriding?

Why should we use data ware housing and how can you extract data foranalysis with example?

Mechanical:

What is second law of thermodynamics and why is it important?

What is refrigeration;Name different refrigerants used,CFC's,

How do IC engines work,


3/6

Name the cars TATA motors have in the market, their enginespecifications,

Do you have a bike? Please tell me your bikes specifications.

Petrol engine vs Diesel Engine. which one is better which gives more fuelefficiency which has low running cost?which has low maintenance cost

Which material is used for propeller shaft ?why? Why do you want to shift from Mechanical Engineering to IT?
