Quanterix interview questions

Had a phone screen with the internal recruiter, a phone interview, and then an in-person interview. Phone screen and phone interview were just the typical, introductory calls. In-person interview was three hours and involved meeting with 6 people within the company. Left the process with a very positive impression as everyone I met with was nice, and the company was good about quick contact and scheduling. However, after the interview I was given a week time frame to hear back and never had another contact again. Extremely rude, considering they want you to sit for a three hour interview for an entry level position. They will sell you on a bright, start-up like culture but clearly are just the same and just as rude as everyone else.
