Lengthy. If you expect to interview on Wednesday for a job on Friday, you will be disappointed. They do not hire people for the near term. They hire people for the next 10 yrs. From beginning to end, for a management position, I interviewed on 5 occasions spanning a total of 9 weeks. Some of this was due to conflicting schedules pushing things out a bit for both sides, but they are most definitely thorough before adding people to their mix. Culture is important and they insist on making sure people are a good fit.
