My first contact with HA&W was at my university's career fair. A few days later I was contacted for an on-campus interview. The interview was with a partner and lasted 30 minutes. The only question he asked me was, "Tell me about yourself." He talked about the firm the rest of the time.
A few days after that I was invited to a firm dinner at a really nice restaurant along with dozens of other candidates and a company tour the next day. We were all put up in a hotel for the night. The whole thing was completely low stress, almost as if they were trying to convince us to work there.
I received an offer a few days after that.
