Atlas Copco Group interview questions

HR Found my resume on a job search website and contacted me for an interview. I was brought in for an interview and was told that they would contact me in a week. I was given the impression that they had an immediate need to fill the position. Three weeks later I had still not heard anything so I left a message with the HR rep who contacted me initially. She never returned my call. It has been over 2 months since the interview and I still have not heard anything back from them. I am less than impressed with their ability to follow up on interviews.
