-Make sure you don't give generic answers, they want to know about you and why you are special, let them know.
- It's a good idea to bring a folder with your resume and possibly some letters of rec. Most likely you will not need them but it shows that you are prepared and I actually used them for one of my interviews
-Make sure you have all of your qualities on mind. It is very easy to forget about important aspects of your life (accomplishments, clubs, parts of sports) because you are so nervous.
-Dress sharp, look neat.
-Relax. These are important interviews but you need to be able to handle high pressure high stress situations if you go to any SA. Make sure that you don't seem too freaked out.
-Be polite, Yes, No, Very nice to meet you, thank you for your time, etc.
- They will most likely ask you what are your strengths and weaknesses, be honest. It does not just mean mental weakness either, i flat out told them "I can not do that many push ups or pull ups but i have been lifting and am working extremely hard to improve in that area". They got a kick out of it and appreciated the honestly. One thing they DO NOT WANT TO HEAR is that you have NO WEAKNESSES, its hard to think of them on the spot, so have some ready!
- Relax and good luck!
