I actually have a friend who just went through 3 months of interviews with the same company. The last interview lasted 8 hours with a panel of executives. In the end, the recruiter asked him to email her a list of pros and cons between his current company and the company he was interviewing with. Why? It turns out that after 3 months of interviewing the employer came back and offered him 30% less than what he is currently making, but tried to justify it with a 10% annual bonus.
One of my first rules of interviewing is to first research the salary range for the position that I’m interviewing for and then ask during the first interview what the company is paying for the position they’re hiring. It is really unnecessary to waste my time and theirs if the wage is not reasonable.
