Prenova interview questions

Had an initial phone interview and it was very brief and went well. Was set up for a face to face interview. Interviewed with two gentlemen and the conversation flowed and it seemed it went very well. After the interview I was shown around the different areas of the company and given a brief description of what they do. I believed due to the great interview and them taking the time to show me around were all good signs. The following week or two after not being able to contact Human Resources about the job I found they had sold the company even though all employees and th elocation would remain the same. I still do not know why I didn't get a follow-up call of any sort and if it had to do with the company changing or the interview itself.
