It was VERY LONG and VERY THOROUGH. I was there for 2 & 1/2 hrs. I completed a typing test 1st, followed by 3 consecutive interviews. Each interview was different than the previous one, but they all wanted to know 2 things (experience and why you should be hired). I was told someone would contact me within the week. I received am offer 3 days later.
Just be yourself, do a little research on the company and what is has to offer. Be prepared to ;et them know how you will succeed in the position. Most of all, DO NOT BE REHEARSED! BE HONEST & BE CONFIDENT. It's ok to stumble. I did quite a few times in my interview.
Please DRESS PROFESSIONALLY. It's better to overdress, than underdress. :-)
Good Luck!
