An important thing for getting into a good professional life is to promote oneself. This doesn’t mean you beat your own trumpet unnecessarily but to express your positive side.
How can one do this is by presenting/explaining your skills? Show all the skills that you have [preferably good ones] When your time has come!
The need for promoting oneself is to stand out among thousands of competitors for a similar job in a similar company.
Think about why should the recruiter select you? If his choice has to be you, in which way are you better than the rest.
Identify that unique quality in you, that is important to the company and present it to the core. If you have to do that, you have to first prepare and discover yourself.
Next, It is all about your convincing skills, yes, convincing the recruiter, creating a positive impact about you in their minds.
They should feel like “Yes, he/she is the one whom I was searching for”. Coming to your appearance, we might have heard this many times, “Never judge a book by its cover” but we often do.
Of course, your looks will create a major impact. Because looks are the most important things in presenting oneself. So, dress up well (In a pretty decent and dignified manner).
So, finally learn to convince, promote, discover, and create a market for your skills.
And yes the last one, maintain a pleasant smile on your face because a smile is the best way to convince and impress anyone.
