Easy interview questions through the first three stages. Was all set to fly out to their Billerica, MA office for final interviews (had the ticket, hotel, and detailed itinerary from them) when I received a last minute email from the internal recruiter telling me they made an offer to a candidate they just met who accepted the offer, sorry it didn't work out for us. The whole ending was very odd and unprofessional. I have seen other positions for the company that would be great fits, but after that kind of treatment there is no way I am returning for more. Not sure how they are rated so highly for company culture...maybe after one is on the inside..?
