Hi, There are some basic points that should be kept in mind while appearing or applying for a job:

1- Highlight the major Points in your Resume as per the Requirement pf the Job. I.e if a job requires efficiency in C++, then highlight in your resume 'Efficient in C++'

2- When you appear for your Interview, study abut the company first i.e what that company is all about & all it deals in.

3- Do a brief Research abut the profile you have been offered. Its future prospects & your growth Chances.

4- When you appear for interview keep up your Confidence level & be strong on your knowledge content. That will help you to prove your points.

5- Be prepared with an answer to the question ' Why should we hire you?' . Prepare all your positive points for this.

6- If you not aware of any question, then don't panic instead simply smile & answer that you are not aware but will surely find out, but do not put up a false answer coz that's where u'll b picked up.

7- Most Importantly: be Humble but confident & As said 'Patience is the key to success', that is how you'll achieve.

Hope these points solved your query. Best Of Luck!!
