- Q9. What is the difference between early binding and late binding?
- Ans.
Early binding and late binding are two different approaches to linking functions or methods to their respective code.
Early binding is done at compile-time, where the function call is resolved before the program is executed.
Late binding is done at runtime, where the function call is resolved during the program's execution.
Early binding provides better performance as the function call is already resolved.
Late binding all...
- Q10. What are functions?
- Ans.
Functions are blocks of code that perform a specific task and can be reused throughout a program.

Interview Preparation Tips
Experience: We were prepared for Quantitative Aptitude, Logical Reasoning, and Verbal Reasoning. But unlike most campus recruitment examinations, most of the questions here were from General Knowledge and Current Affairs. But most of these questions were school-level GK.
This written test was conducted on 2nd August. Results were declared on 8th August.
Duration: 1 hour
Total Questions: 60
Round: Technical Interview
Experience: Although JCI is a core company, but the interviewer asked me questions from basic C and Java.
Tips: Keep the basics clear. And if you are from IT/CS, don't fret about the fact that they'll ask questions from electronics and electrical subjects as it is a core company. That is a mistake I made. Have strong knowledge about your own domain and you'll easily crack the interview. All the best!
