"If you’re not different then you’re boring." That's not true at all. If you send us a poster, a video or (god forbid) a song you wrote, we'll wonder if you can get along in a work environment. This isn't summer camp, it's a job. We want to know if you can do the work.
"dress accordingly to the company’s culture" - no, no, no. Dress like you want the job. When you work here, you can dress however you want. Most people wear jeans and t-shirts. But showing up to an interview like that looks like you don't really want the position. Put a tie on. Even better, wear a suit.
"If you can’t be genuine, real and comfortable in the conversation then forget it." If you can't be comfortable in an interview, then you're human. We recognize the inherent stress in an interview. Don't worry about appearing aloof. We'd rather you be anxious to get the job.
