SGS Microbiologist interview questions

I first met with the manager and had a one on one interview. I was then given a tour of the facility before meeting with the supervisor and having another one on one interview. Both were very friendly and answered every question I had regarding the position.

First round of interview was with HR and went pretty smooth, next was face to face interview with manager. They looked very impressed and said will get back to me about the hiring decision. 4 weeks and NO reply from their end at all. Finally I had to contact them back and heard that they choose other candidate. Highly unprofessional when it came to communication.
