In many ways, the first impression in an interview is the most important one, so make sure that you:
Without being pushy: (a) Sell yourself. (b) Sell your skills. (c) Sell your potential. People you meet will imagine working with you and how you will fit into the team. This is why it is important to make a positive and enthusiastic impression in the first 5 minutes.
Remember – don’t be defensive. Even if it seems the interviewers are being tough on you, they want you to succeed.
