Phone interview first. Very basic technical question. (ex. what is TCP/IP...what does it do)
Then face to face interview with both IT managers. Some troubleshooting questions (fix a problem with a network printer). Analytical question (guess the number of gas stations in the US). On the same day, met with the IT VP. A lot of personality type questions (handle conflicts, etc)
This is a business casual environment since it is an investment firm. No jeans and tshirts.
