Common Job Interview Questions for Software Developers

If you are a graduate in software engineering and looking for a job or an experienced software developer looking for a job change, you are going to face some common job interview questions which you should prepare before appearing in job interview. These common job interview questions include OOPS concepts, common database concepts, questions to test your problem solving capabilities and some tricky HR interview questions. I have made a list of interview questions which might help you in your job interview preparation.

A. OOPS Interview Questions

OOPS concepts are almost common in all the programming languages. So, you must prepare basic and advanced questions on OOPS. I have listed down some of the OOPS interview questions which you should know before attending the job interview.

1. What is a class and object?

You should also prepare some commonly asked HR job interview questions beforehand. I have seen many candidates who clear all the technical rounds but get trapped in HR round. Your HR round should be smooth to crack the interview. I have listed down some of the HR interview questions which you should prepare before appearing in the interview.

1. Tell me about yourself.

2. Why should I hire you?

3. What are your strengths and weaknesses?
