Questions posées lors d'un entretien d'embauche de International Trade Regulatory Research Assistant chez Bryant Christie

Applied for the job and was invited for a phone interview which I was told to wait for decision 1 week later. Never heard back so I sent a follow up email asking about the status 10 days later. The interviewer sent an email 3 days later stating they were busy and told me hiring process was still continuing and I would be contacted with more information within 2 weeks. Still no respond in the next 2 weeks so sent a second following email asking if the position was still opened on the first day of the 3rd week after the email respond from the interviewer and still no respond. I feel it is extremely unprofessional to avoid individuals who have applied to a position and taken time to interview. I understand they might be working on several projects at the same time but I dont think it is apporpriate to promising interviewee a time range yet constantly breaking it. I can't imagine it's a caring workplace if they can't even reply to a person interested in working for them and so poor in time management.
