Tips for B. Tech CS students to Crack Technical Interview


If you are a B. Tech CS student, you will have to crack the technical interview if you need to get a good job. Now that you have completed your B. Tech CS course, it is time for you to start preparing for your technical interview. You should know how to prepare yourself for the same and how to crack the technical interview. The following are some tips that can help you in your preparation and cracking of the technical interview:

Technical Interview

When you land a job offer in your dream company, the excitement can get overwhelming. But before you start celebrating, you need to prepare for the technical interview.

The technical interview evaluates your expertise in certain programming languages and technologies that are related to your field of study (B. Tech CS). It's one of the most essential parts of getting hired by a company because it helps them assess whether or not you have enough knowledge to handle their projects effectively.

Companies want candidates who are passionate about their work and are familiar with current technologies and also are from well reputed institutes in India. Because, they want someone who can bring new ideas into their team and make an impact on development processes.

"Prepare thoroughly for the interview"

To prepare for the Technical interview, a B. Tech CS student should:

  • Study the company's website. Look at their products and learn about them as much as possible. Find out what makes it unique and how it differs from other companies in the same industry.
  • Read through the job description carefully, paying attention to any keywords that may be used in your answers during the actual interview. For example, if they advertise that they are looking for someone who is "entrepreneurial" or "results-oriented," those words should come up in your response when asked what you bring to an organization and why they should hire you over others who might apply for this position. Try writing down some ideas beforehand so that you have time to think during each question (rather than having to think on your feet) without worrying about running out of time before answering each one completely!
  • Study what makes this particular company unique relative to its competitors—both current ones and potential ones (if there are any). This will help inform which questions are relevant in determining whether or not someone would fit within their culture/mission statement/etcetera...

1. Data structures and Algorithms:

Data structures and algorithms are the foundation of B. Tech CS. If you can’t understand how data is stored or processed, then you won’t be able to write software that works. You should know:

  • The difference between a linked list and an array
  • How to sort an array
  • How to find the median of an array (this is called quick sort)
  • How to find the minimum or maximum value of an array (binary search)
  • How to find the sum of an array

2. OS:

OS is the software that manages computer resources and provides common services for computer programs. OS is the most important software of a computer. In fact, it is the backbone of the computer system. It controls everything from memory management to printing out data on your printer. So, you can say it's one of the most complex pieces of software in any machine (including humans).

If you are looking for a job in IT industry or some other related field like embedded system development where server side programming languages are used then knowing about operating system is necessary for every interviewee because there might be some questions asked from this topic by interviewer during technical interviews at companies like Google etc..

3. DBMS:

  • Relational databases:

Relational database is a DBMS that uses the relational model of data. It is a wholesome subject in b. Tech CS. It consists of a number of tables, each one containing rows and columns.

The table names are referred to as relations, while each row and column are called records and fields respectively. In relational database management system (RDBMS), it is possible to define relationships between different tables by creating foreign keys which refer to primary keys in other tables. This allows you to store multiple pieces of information about an entity in one place so that they can be easily accessed simultaneously.

  • Normalization:

Normalization is the process through which we convert data from its original form into a more suitable format for storage in a database. Normalization reduces redundancy by breaking down complex data into smaller parts that have fewer relationships with other parts than with the whole set of data

4. Networks:

  • Network interviews are more common than ever for a B. Tech CS student. These interviews are usually held remotely, and you may be asked to do a technical phone screen on your own time. Make sure you have a quiet place where you can focus and not get interrupted during this call.
  • This type of interview is less formal than the traditional on-site interview because there is no interviewer present in person; it’s just you talking to someone over the phone while they listen in.
  • Ask questions! Network engineers( B. Tech CS students)  want to find out what makes you tick, so asking questions about their role at the company can help them figure out if they want to work with someone who cares enough about their job to ask these types of questions

5. Aptitude and Reasoning:

Aptitude is the ability to reason logically, solve problems and think abstractly. We all have varied levels of aptitude and some people are naturally good at it while others need more practice. Aptitude can be developed if you practice regularly.

Aptitude means being able to do certain things easily or quickly. For example, if you find that you are very good at solving mathematical problems ( Which A B. Tech CS student already is), then you would say that you have a high degree of this aptitude for math.

Similarly, if someone is good at remembering things like dates or names then they would also be said to have an above average level of memory related ability or "memory" (i.e., their capacity for storing information). This type of capability is called as “memory” which may either refer specifically to long-term storage or both short-term recall and long-term retrieval respectively depending on context."

6. Fault tolerance, Etc.:

As a B. Tech Cs student, you should have a good knowledge of fault tolerance, exception handling, etc. is important to know. The interviewer will ask you to explain the concept in detail and then he will give you a problem to solve it on the spot.

To do well in an interview need to work hard on these topics.

In order to do well in a B. Tech CS interview, it is very important to work hard on these topics. The following are the most important topics that form a part of the syllabus in B. Tech CS:

  • Data structures and Algorithms
  • OS (Operating System)
  • DBMS (Database Management Systems)
  • Networks (Network Fundamentals, Comm. Layers, Transport Layer, Application Layer)
  • Aptitude and Reasoning

You should also prepare well for interviews on other subjects as well like:

  • Fault tolerance, Etc.

Your technical interview is going to be hard, but you can do it if you prepare in advance!
