The interview process was evolving to behavioral based interviews. Issues they may ask may be:
Tell us about a time when you had a problem with an employee that required discipline, how did you handle it.
Tell us about a time when you had a work flow problem and how you overcame it.
The culture was evolving as well, it was a male dominated culture and was not conducive to those who did not drink. Attitudes and people were becoming more professional on an ongoing basis.
