I went through 4 rounds starting with HR call, then the call with hiring manager & director. There were 2 more rounds after that of case study presentations where they gave a case problem to solve and 1 hour for me to get back with my findings & insights.
I applied through a recruiter. The process took 3 weeks. I interviewed at HSM Consulting (Boston, MA) in Mar 2014
Interview
You talk to a nice recruiter and they offer a ton of money. Then when you talk to the VP you realize you made a mistake. They will get you to quit your job on the premise of having this great job at HSM then when they don't win the business you will be on the bench, before long they will start threating to let you go if you don't get booked on a project

Question 1
How long have you been a consultant? How many times have you led a team or project and were you successful?
I applied through an employee referral. The process took 1 day. I interviewed at HSM Consulting
Interview
The hiring and interview process was very fast (rushed in hindsight) and streamlined. After a 20 minute conversation with the VP I had an offer on the table and within 24 hours had been hired on.
