I had a phone interview with HR and then I came in person for a series of interviews. Some were with team leaders and one I was asked to do a sample task looking at a printed out sheet of some data. After the in person round of interviews I was told that if I moved to the next round I would meet with the CEO. I was never contacted about scheduling the next round nor to indicate that they had gone in another direction, which I found highly unprofessional after an in person interview (this has never happened to me at any other company).

The interview process was very lengthy. I was first contact about a phone interview that took almost 45 minutes. After that, i had 2 more phone interviews that each took about 30 minutes. The phone interviews felt pretty casual and they seemed more interested in my as a person than my resume. After the 3 phone interviews i was invited for 4 face to face interviews on-site. The on-site interviews took about 3 and a half hours and i met with 2 of the people i had alreayd had a phone interview with. I meet with all 4 people back-to-back. Shortly afterwards i was invited to write a letter to the CEO in an attempt to get a final interview. I sent the letter and was declined an offer a few days later.
