Computer Science is one of the most profitable graduates ; s through engineering, mathematics, science and business. As a computer science graduate, you can earn an average salary of $ 50 - $ 130,000 per year . In this area, you will also have great potential for growth as salaries for IT professionals are known to increase dramatically from year to year.
Computer technical interview questions
What is a class and a superclass?
The answer to this question is similar to the others should be at the beginning of the language. You can answer this question as follows:
A class defines the project from which the class objects are created example, the characteristics of an object and with which methods and variables it is associated. A super class, on the other hand, refers to the considered direct class.
What is the difference between Process and Thread?
Although a process and a thread may seem conceptually similar, the two are independent sequences of execution. You can answer this question as follows:
Process is a running program. The thread is a segment of a process, which means that a process can have multiple threads.
Compared to a thread, the process takes longer to complete. The process also takes longer to create while the thread takes less time. The process is isolated while the threads share memory.
What is a constructor?
In object oriented programming, a constructor is a method of a class or structure and initializes an object of that type. Your answer might look like this:
Most of the CS interview questions as discussed above will revolve around similar concepts.

Behavioral interview questions
When preparing for an IT interview, do not assume that the hiring manager will only ask questions. technical issues. The behavioral interview questions have become an important part of the recruiting process in most companies. This applies to both tech giants and startups.
Behavioral questions are typically worded like this:
Tell me about a time when ...
Describe a situation where ...
Give me an example of a time ...
The purpose of the behavioral questions is to allow the employer to understand the results you have obtained in your past work experience. For example, how you applied your knowledge and skills from your previous job to take concrete " action ‚". This action could be a task that you completed successfully, a team that you managed, or an actual issue that you resolved.
The interviewer can also ask general questions. For example:
Tell me about a time you disagreed with a colleague. How did you handle the situation ?
Make sure to review your resume several times before the interview so that you can answer any resume-related questions as well.

Preparing for the interview is not an easy process. It takes time and dedication. And this is especially true when it comes to preparing for IT interviews. Each company has a different way of interviewing. You can see sample interview questions for the job on sites like Glassdoor. That way, you can get a feel for the type of questions they might be asking you.
Also be sure to go through the hiring process after the interview. If you don’t get a response from the hiring manager within days, you should contact them and request updates. This shows them that you are still interested in the job and that you know how to take initiatives.
