In this section we will tell you how easy it is for a fresher to clear a technical interview stated if he follows the basic tips/rules/mantra:
Technical Interview is part of the recruitment process for almost all the companies and this is the second biggest elimination round after the written test.
Well, I will assume here as you are a fresher trying to get into a software company (since most does irrespective of their branch).
Any software firm small or big wants their employees to know the basics of the subjects like,
- Programming
- software engineering
- operating systems
- Databases
- Computer Networks.
Having said that they won’t expect you to know every part and parcel of the subjects, rather they would look for someone who at least knows what they are for.
Now if you are asked to write a C-Program which does check whether a given integer/string is a palindrome or not (which is part of lab programs for almost all the universities in the country in the 1st year), he would expect that you will write it easily and if you fail to do so, please don’t expect him to select you.
So what would we suggest is that, you should have basic knowledge on the aforementioned subjects and we will also tell you the areas you should concentrate in each subject.
1. Programming
In any technical interview, it is obvious that you would be asked to write some programs and mostly in C,C++ & Java .
To be confident at this area, you should know the basic syntax of all these subjects as the semantic or logic remains the same.
Start with C, learn variables, operators, control structures, functions & pointers (the most important stuff), structures and files. Then go for C++ and java, try to understand the differences between all the three precisely.
OOPS is the most important & probable topic, where you might get questions from.
Below is the list of the most frequently asked programs that you must learn to clear this round.
a) Write a C program to swap two numbers without using a third variable.
b) Write a C program to check whether the given number or a string is palindrome or not.
c) Write a C program to create a Pascal triangle.
d) Write a C program to perform matrix multiplication and addition.
e) Write a C program which performs bit manipulation (&,|,etc) of a given number.
f) Also, learn programs which does basic file manipulations (creation, writing data and reading)
We would post some more programs which are important, with the complete code J in a separate section.
2. Software Engineering
This is the most important & also a boring subject, since it is mostly theoretical.
Not many interviewers ask questions on this subject in the technical interview, but it is always better to know the basics and be on the safer side.
Questions in this subject would be basically on the following topics,
a. Phases of Software Development Life Cycle
b. Process Models like Waterfall model, agile model etc.
c. Cyclomatic complexity of a software
d. Basics of software testing(white box, black box testing)
If you can learn all these, then you could possibly answer all the questions in the interview.
