Entreflow Consulting Group interview questions

I got call for introductory interview a week after submitting my resume. A day after, I got an email to set an online interview. During the interview, the interviewers include a HR staff, a HR manager, a head account, and a financial department manger.

After several phone interviews and several face to face, including an exercise to complete I was told via email they would get back to me by week end. That was over a week ago and nothing. Very telling I think - either ignorant/rude or no real plan for growth.
