GFI Software interview questions

After several months (4) waiting for assessments to be completed. I finally received an interview offer. First interview was cancelled less than 1 hour before it was due to start. Second interview was cancelled just over an hour before it was meant to start. On both occasions, I have taken time out of a project with a strict deadline to attend. No apology was offered for either cancellation. After the second interview cancellation, I withdrew my application. I'm not going to work for a company that holds so little regard for their potential employees.
